Sample Customer Review:

“Absolutely satisfied with this amp. I bought two of these to pair with the two Planet Audio AC12D 1800w subs I bought and I couldn’t be happier with the result. In other reviews and even other websites there is a lot of negative feelings towards this amp and it’s output ability.

I have not tested for actual amperage or watt output but paired with a single 12” sub this amp performs excellent. You can spend twice as much on an amp and get better performance but not everyone has that kind of money to throw around. If you want competition quality you have to spend the money for it. If you are just looking to add some serious bump to your trunk, save yourself some cash and go with Planet Audio."

Refer to the Installation Manual for complete details – Power input: 7.5A, 1/0 AWG Power wire size needed 12ga or larger.

Variable gain control allows you to match the amp’s input sensitivity (gain) to the output of the source unit as well as improve sound quality and noise level. You can adjust input sensitivity so that noise or distortion is reduced and sound quality is improved.

The Boss AR2000M amplifier’s variable crossover is a great feature that allows you to control the bass. With this, you can target certain frequencies so they don’t mess up your speaker system. The variable low pass filter for the subwoofer lets you set the cutoff frequency between 50-200 Hz at 24 dB/octave. This lets you craft your own sound to get the bass you want.

BOSS Audio Systems AR 2000M Monoblock Class AB Amp 2-Channel Car Amplifier Bass Remote Control Variable low pass crossover is a feature that allows you to adjust how low or high your speaker’s frequency will go before they are cut off by the amplifier. Variable bass boost gives you great control over the amount of bass you want to add to your music.

This amplifier comes with a wired remote (bass knob), which can be mounted and used within 10 feet of the amplifier for quick adjustments on the go. The maximum power output is 50 watts RMS at 8 ohms and 100W RMS at 4 ohms per channel, adding up to 2000 watts of total power. It’s more than enough power for your vehicle’s factory speakers or aftermarket speakers.


Nothing a lot of things in negative about this product only the wiring in the power cable makes it hard to use anything other than the cables that come in its package, and this can be very inconvenient if you want to add bigger speakers or upgrade your gear.

Sample Customer Review:

“Ive purchased the 1500 watt A/B boss amp and now currently have purchased the 2000 watt A/B amp. Ive already got 140mm corsair high flow cooling fans (4 pushing and 4 fans pulling). I could barely turn the 1500 watt amp up as it was only pushing a single Premier 10” sub. However the back of the sub says 1,000 peak watts… I’m sure my 1500 boss amp wasnt pushing close to its peak number but I ended up blowing the 10in sub because I turned the bass knob right blow half way and the gain wasnt even turned but just above a quarter of its starting point.

I just purchased 2x 12in mtx terminator subs and will install this 2k amp with those. I did think the 2000watt boss amp was class D. But I got the 1500 back in 2016 and it still bumps hard.. Just my little sub couldnt take it. I also have a jeep liberty so everything is enclosed.

I’m stoked to hear the 12s as ive only had the 10in… If the boss amp handles these with no problems I’ll upgrade my subs… Since I put the amp in my fan box ive never had it go into protection mode again and it keeps the bass going… No clipping even when turning it up."


The Rockford Fosgate R250X1 Prime 1-Channel Mono Block Amplifier (250 watts at 2 ohms and 125 watts at 4 ohms) is a high powered amp that provides up to 250 watts which can be used in mono or bridge mode. It has many inputs, one for balanced XLR, one for unbalanced 1/4" and one set of preamp inputs so you can connect RCA cables from your head unit.

The front panel has control for gain, a 12 dB / octave Butterworth crossover, a bass EQ with adjustable frequency and cut-off point. It also has Rockford’s Punch Bass boost at 45 Hz. The subwoofer output has the same features as the front.

The R250X1 Prime Amp has a variable low-pass filter with a slope of 24dB per octave so you can adjust for best sound either high or low pass depending on your speakers. It also includes speaker level inputs along with preamp outputs. All together this amp has everything you need to produce great sounding music.

The cast aluminium heatsink is where all the magic happens. It provides the perfect blend of airflow and heat dissipation to maximize power output while keeping it cool at the same time.

The Stealth top-mounted control panel allows you to see all the knobs in detail, but still keep it a sleek look without adding too much bulkiness to your car’s dashboard. The flat black paint along with the silver accents will look amazing whatever vehicle you put it in!

How “Carbon Resistor” works for Rockford Fosgate R250X1 Prime

The carbon resistor is perfect for low, medium or high powered installations. It’s a non-inductive resistor that provides a pure sound without any coloration providing a smooth tone. It can handle up to 135 degrees Celsius and above for short periods of time, thus making it perfect for high powered car audio sounds.

If you have a factory-installed or aftermarket source unit, the R250X1 works with it. Additionally, if you upgrade to an aftermarket stereo in the future, this amplifier will still work.


The only con I could think of with this amp is that it does not have a built-in fuse for the power and speaker output. However, most people with an amplifier usually install one on their own just to be safe anyways.

The R250X1 is definitely a heavy amp, so you will definitely need to add some weight to your trunk if your car struggles with the extra bulk.

“Great Bass Sound ..it’s only Small But Sound Perfect.”


Skar Audio has just recently come out with a new series of high powered amplifiers called the RP Series. Today we will be reviewing one of their newest models, the RP-1500.1D Class D MOSFET Monoblock amplifier. Skar Audio’s amps have always been known for being extremely powerful while also maintaining great sound quality.

The RP series amps continue this trend by offering huge power, low impedance capabilities, and remarkable sound quality.

This amplifier also has an optional remote subwoofer level control that allows you to wirelessly adjust the volume of the subwoofer from inside of your car.

One another great feature of the RP-1500.1D is that it is stable at 1 ohm, which is perfect for anyone looking to power two 8" subwoofers. All of these features make the Skar Audio RP-1500.1D Mono amplifier is a very popular choice for anyone looking to power their subwoofers with massive amounts of power.

The Rp-1500.1D is a class D monoblock amplifier, which means that it is more efficient than your average class AB amplifier. The amp has a MOSFET power supply and a high current 4 gauge power input terminal for the best possible power transfer to your subwoofers or speakers.

Not only does this little beast of an amp produce much more power than it’s rated for, but it is also very efficient. The built-in 4-way protection circuitry protects the amp from damage caused by power surges, DC offset, overheating, or subsonic frequencies that can cause possible speaker damage.

The Frequency Response of this amp goes from 20Hz all the way up to an ear-shattering 250Hz. This gives your subs a nice low rumble that you can really appreciate. The onboard Bass EQ switch offers +6 or 12dB at 45HZ, which will allow you to adjust the bass according to how big of a bass boost you desire.

The peak power rating for this amplifier is 1,900 watts @ 2 ohms and the RMS power rating is 1,500 watts. This rating means you can run multiple subs off of one amp without the worry of it being underpowered. Since this rating is so high, these amps are not designed to be run on a daily basis at full power.

A recommended range for most people would be to run the amp at 1/2 – 3/4 power. This will allow the amp to remain fully protected from thermal and overdriving issues while also giving you a more powerful sound as many car audio enthusiasts prefer this option.

The RP-1500.1D is a monoblock amplifier meaning it is meant to power one subwoofer at a time. This amp produces 1500 watts of power and can only be used on a 1-ohm load or greater. Included with this amp are high-level input wires that will accept an RCA signal from your head unit, but it also comes with a remote wire that will turn the amplifier on and off.

This Class D MOSFET Monoblock car audio subwoofer audio amplifier is famous for its high current capacity, meaning it can produce more power at a lower impedance compared to traditional AB amplifiers. This technology provides a much better bass response producing more output even from an amplifier with a relatively small footprint.

One of the best features of this amplifier is that it can be bridged in order to power a single 4-ohm subwoofer, which is an excellent way to get more output from your system when you decide to add a second subwoofer later. In addition, the amp has built-in thermal, overload, voltage and short circuit protection in order to make sure all of the components are well protected.


Well, it would be nice if the remote level control was included with this amplifier, but this is an excellent amp for anyone looking to power a subwoofer or two and doesn’t want anything else. The amps’ high current capability and output make it perfect for powering your subwoofers at a very affordable price.

Sample Customer Review:

“Ive been testing this amp for about 1 month hiting it hard with all my low end bass songs like trap, drum n bass, trip hop, old school bass music and it has never quit on me yet and when i mean never quit i mean taking a 3hr trip just banging all the way song after song. For the price im impressed and i got the white marine amp as its the same as the black just because my suv is white. I have thos on a jl 13.7 v2 ported box tuned to 34hz.”


The Alpine A60M amplifier is a Class D Mono Amplifier, which has twice higher efficiencies than standard Class AB. And it helps the amp to run cooler and achieve more output power from the same size of heat sinks. S-A60M delivers massive power combined with super low thermal noise and ultra wideband frequency response for a powerful music atmosphere in your car.

A60M is specially designed for the subwoofer. The design starts with an efficient core of the amplifier, then uses a high current low impedance power supply with a multi-stage direct charge pump to produce maximum output power. It has additional features like Ultra Low Noise (1dB), Aluminum alloy heatsink, precision 0.15% tolerance voltage, protection circuit, etc.

2 x 2 Ohm simultaneous load capability for subwoofers Class D amp is more efficient than standard Class AB and able to run cooler and achieve more output power from the same size of heat sinks, which is helpful when you are doing high-power amplifiers.

When this amplifier is combined with the US-1800 Ultrasonic Aluminum Subwoofer, it can achieve super-powerful bass effect of more than 900 watts output power. The Alpine A60M  amplifier is an ideal amp for any 12" subwoofer driver. MOSFET PWM power supply for high-speed switching and efficiency Provides powerful, reliable performance in a compact size with lighter weight.

Super Low Noise (1dB) Low noise design ensures that the signal passes through quietly, even at high volume levels. Precision 0.15% tolerance voltage extremely accurate output voltage ensures optimum sound resolution and clarity for both channels, which means you, can also adjust the subwoofer level to your taste.

Protection circuit on the speaker outputs Protects speakers from damage due to short-circuiting or mismatched impedance, by shutting down output temporarily.


Found out the hard way that the ‘Mode2’ is not mentioned anywhere on the amp, but yet it runs at 8ohm instead of 4ohm even though this amp has a 4ohm stereo RMS power output.

So, if you have your speakers set up at 8ohm on your receiver/pre-out, this amp will lose about half of the power it would have at 4ohm. So instead of having 400watts to drive your speakers with, you only get 200watts to drive your speakers with.

Sample Customer Review:

“This little guy packs a punch on my birth sheet it was rated 816 actual watts when tested so it has the potential to crank out 800 instead of the advertised 600 which is amazing i have it connected to a small 8 inch type r and with all the settings properly adjusted it makes the little 8 sound like a 10” or even better than a 12" very impressed so far and it I tiny which helps with mounting options."

Sample Customer Review:

“This is a badass little amp! Well, I shouldn’t say little because this thing is HUGE! I purchased this to replace a Rockford Fosgate Punch 400×4 that died in a little over a year of light use. Given the fact that this unit is a fraction of the price of the RF, I wasn’t expecting the world – I just wanted my sound back!

Upon unboxing I immediately knew the size was going to be an issue. Unfortunately, this unit is twice the length of the RF so I couldn’t fit it in it’s old spot. Not to worry, some not-so-clever mounting and I was on my way.
Size aside, I was immediately impressed once I turned on my head unit and started playing some music.

The clarity beats my RF unit by quite a surprising bit. Everything sounded better, every frequency band sounded great through my RF Punch 6.5” components! It definitely got louder, but to be fair this unit is slightly higher wattage.
TLDR: This amplifier delivers. For the price, I really don’t think you can beat this as an entry level unit!"

The only other downside is the low end frequency of this amp. Its crossover is limited to 80 Hz which can be bumping up against your subwoofers cut off point. This makes it necessary to use an external processor with the high level inputs if you want to tune in more bass response.

Sample Customer Review:

“Love the compact size and the available power. Perfect for driving a 12” kicker sub in my truck. I like the removable cover that keeps all your frequency adjust and base controls hidden."

The pioneer car amplifier is great. I don’t have any problems with it. It’s very powerful and loud but doesn’t distort my speakers. The only downside to this product would probably be that the subwoofers act up at times, but you can just shut them off if they do. It might just be the wiring of the speakers.

Sample Customer Review:

“Daily driver use i beat the crap out of this amp since 2019 & keeps playing 2/0 power with reducers. 1 time i replaced it with more powerful amp yes other amp was stronger But full bridge i did notice sound difference i took it out put back my little pioneer 1200 watt amp back again. Maybe if it wasnt a daily 2 hour driver i woulnt had mine the Full Bridge sound.”


As a car audio enthusiast and music lover, the Kenwood KAC-9106D Monoblock Power Amplifier is an amplifier that I find extremely useful in my own vehicle. When searching for an upgrade to my current CD player, wanting to add some extra power and bass to my sound system, and wanting to keep it at an affordable price, this amplifier was a perfect choice.

The amp itself has a power output of 2000 watts max for each channel, and there are 2 channels total in the amplifier. This opens up opportunities for multiple speaker setups in the vehicle with still having enough power to go around.

This amplifier is great because it offers excellent power for an affordable price. One of the best features about this amp, in general, is how it has a built-in variable low pass crossover with separate gain controls for high and low pass, which allows you to adjust the sound even more to meet your own personal preferences.

Another thing that I like about this amplifier is that it comes with preamp stereo RCA level inputs along with speaker-level (high, low) input connections to allow for easy installation.

One of the things I appreciate most about this amplifier is how it has electronic soft clipping circuitry. This allows for a more smooth sound at higher volumes, while still giving that traditional “clipping” style sound when you want it, or needed to get an extra kick out of your bass. Another thing I like is that this comes with variable high and low pass crossovers.

Which allow for you to adjust the settings of your sound system to better meet your needs and preferences. Finally, this amplifier comes with a bass boost remote control (variable 0-12 dB), which is very useful in allowing me to make my audio sound exactly as I want it, and need it to.

One thing I like about this amplifier (and most class D amplifiers in general) is how it has a variable low pass filter. The cutoff frequency can be adjusted anywhere from 50 Hz to 200 Hz at 24 dB per octave, allowing you to adjust the sound coming out of your car speakers to your preference.

This is one of my favourite features of the amplifier because it allows me to adjust how much bass I get from my music or movie soundtracks.

Another great feature of this amplifier is the speaker outputs. The amplifier has a set of high-level inputs, making it simple to install with a factory radio or aftermarket unit. There is also a set of screw terminals for the low-level input connections if you were using them instead. I like how both sets of speaker outputs can be used at the same time, which allows you to get twice as much power.

Another thing that I found useful about this amplifier is how it has powerful connections. The power terminals are designed to accept 12-gauge wire, which can easily handle the current needs required for this amp. This makes installation even easier than ever before.

The Speaker-level inputs with signal sensing turn-on is one of my favourite features of this amplifier. With most amplifiers, you have to run a remote wire to be able to use the speaker level input connections. However, with the Kenwood KAC-9106D Amplifier.

This is not necessary because it has a built-in connection for the speaker wire so you do not have to run a separate wire if that is what your installation requires. All of these different features allowed me to find the perfect upgrade at a good price for my sound system.

I would recommend this amplifier because of all the different customizable features. The price is affordable and fits any budget. It has enough power for a majority of people and is easy to install. If you are looking for an affordable way to upgrade your sound system or just have that extra power, then this amplifier would be the perfect choice.


The most negative aspect about this amplifier is that it is very sensitive to being affected by the heat of the engine. Therefore, I would recommend a capacitor or an extra fan if you live in a hotter area and want to prevent possible damage from happening due to excessive heat.

Sample Customer Review:

“This amp pushes both of our .5 Cubic Feet sealed for each 10” Rockford Fosgate P3 Shallow DVC (2ohm/2ohm) @ 600 Watts RMS for both subs running a Series/Parallel Connection to both DVC Subs resulting in this amp puching 500 RMS Watts @ 4 ohms to these ear wax moving King Crew Cab Pounders! (2016 Ford F-150 under rear bench seat barely visible) This amp will pound & Pound & POUND in this configuration barely getting warm. Speakers SOUND tight, just when I think they cant hit any harder.. they do.

Other Pros this amp offers: High-Level Input, this is great not only to avoid wiring to the head low-outputs rcas, but it also allows you to skip finding an Ignition Remote Wire and wiring it because the high level input is “auto-sensing” not requiring you to run the Remote Turn on Wire. $ Just give it a couple high speaker inputs (We used 60 watt per side highs from a Sony head unit/amp and it worked fine even though the manual says high input is 50 watts RMS max) and a power wire! and you are ready to go. AND GO STRONG YOU WILL If you know how to properly use its god given gift to push insane amounts of juice into your drivers."



The Rockford Fosgate P500X1BD Punch car Amplifier is an easy to use car amplifier that will be exactly what you’re looking for if you want to upgrade your sound system. This mono subwoofer amplifier has enough power to drive one subwoofer with up to 500 watts of maximum power, so you can experience a much better sound in your car.

The Rockford Fosgate P500X1BD Punch features internal crossovers that make it easy to set up and use without any hassle, and the MOSFET power supply makes this amplifier capable of delivering all this power safely. If you want to get a better sound system in your car and you don’t know where to start, the Rockford Fosgate P500X1BD Amplifier is exactly what you need.

This amplifier contains class-BD technology.


Class-BD technology produces bass more efficiently over traditional amps. A Class-BD mono subwoofer amplifier delivers high efficiency with minimal heat production due to its ability to run cool at higher farad capacitance and increased amperage.

This increased efficiency allows for cleaner, continuous power output without the need for increased heat sink mass, increased size or decreased efficiency.

The Punch P500X1BD is a class-bd mono amplifier. Class-bd amplifiers employ MOSFET power supplies and switching techniques, which allow for the efficient delivery of high output power over a small number of amplifier electrical components. This design provides the benefit of higher efficiency than traditional designs as well as lower heat production and a more compact chassis design.

The Punch P500X1BD has a maximum power of 500 watts at 2 ohms and an RCA pass through the output to feed an additional amplifier. It also features a variable Crossover with 12 dB per octave Butterworth style filters, adjustable Punch EQ controls (+18dB boost @ 45Hz), and C.L.E.A.N. set-up capability with included setup microphone for easy installation.

These features allow the user to customize their sound system for full-range music playback, high output subwoofers, or a combination of both equally loud volumes.

The RCA inputs on the Amplifier can accept both high and low level audio signals without the need of a signal converter. In other, more simple words, it features a speaker-level input that allows users to tap into their factory radio’s speaker-level output and send it to an amplifier.

This makes it easier for users to add sound equipment such as a subwoofer or an aftermarket head unit without having to cut wires in their factory wiring.

This amplifier will deliver 500 watts of power to a single subwoofer with ease, and it’s small enough that you should have no trouble finding a spot in your car to install it. You won’t need any additional wiring or parts for this amplifier to work as well as it should, and it’s designed to be as safe as possible.

If you want a simple amplifier that will let you upgrade the sound system in your car without spending too much time figuring out how to set everything up, this could be the one you need.

If you want a simple amplifier that will let you upgrade the sound system in your car without spending too much time figuring out how to set everything up, this could be the one you need.

The only problem users reported with this Amplifier is that it doesn’t get too loud. This isn’t really a drawback because this amplifier was designed to be used to upgrade factory sound systems, so you shouldn’t expect it to produce the same loudness as a 1000 watt or higher amplifier.

Other than that, users liked this product because it’s easy to install and the sound is great for an upgrade in your car.


This amplifier actually has no drawbacks at all. Small in size, nice perks like C.L.E.A.N set-up capabilities and internal crossovers, and a class-bd design mean it’s one of the best car amplifiers on the market.

Sample Customer Review:

“I installed this in my c300 2009 Benz. I tapped off the rear sub w/ a line converter into this amp. During their ‘CLEAN’ install the amp didn’t clip on the input full volume.. nore did it clip on the output with the gain all the way up. wild. it kicks hard. I power a 12” P3 punch with it, custom box, absolutely amazing."


Monoblock amplifiers are specifically designed to power one pair of speakers. This is because the amplifier’s internal components can be built into a single unit that provides an enhanced signal-to-noise ratio, which results in better sound quality than its separated counterparts (e.g., stereo amps).

Monoblock amps also use less power than stereo amps. This means they do not need to be connected directly to a power outlet and can use less current than their separated counterparts, which lowers the impedance on your household electrical wiring system.

Wattage Considerations:

-Always buy more power than you need. A general rule of thumb is to go with an amp that has twice the wattage as your speaker’s peak watt rating (if you’re using multiple speakers, make sure each one has at least double the peak watts). For example, if your speakers have a peak wattage of 300 watts, look for an amp with 600+ watts.


Monoblocks should have a minimum impedance of eight ohms. The lower the number, the more difficult it is for your amplifier to power that speaker pair and vice versa. If you buy an amp with a higher impedance than your speakers require, they will not produce their full sound quality potential as there is less wattage available from the amp.

You should always consider your subwoofer’s impedance when choosing an amplifier. If you are not pairing a monoblock with another amp, make sure to buy one that matches the impedance of your subwoofer.

So consider the impedance your speakers require (ohms). This is important because it will determine how you wire up your amplifier to ensure that each channel has a matching ohm load. To match the amplifier to the subwoofer’s impedance (ohms), use this simple equation:

If you’re using multiple speakers, make sure the ohm load is divided equally. Consider this example with two 100 watt speakers and a 200 watt amp:

100+100=200 (the total ohms of both channels). So as long as each speaker is rated at 50 or higher for impedance, then they can be wired together in parallel (positive to positive and negative to negative).

Frequency response:

– Consider the amp’s frequency response when buying an amplifier for your speakers. The frequency response is basically how low or high it can play sound (measured in Hertz). For woofers, you want to look at a full range of 20 Hz to 200 kHz; if you’re using midrange speakers, 40 Hz to 20 kHz and for tweeters, it’s best to look at a full range of 200 Hz up to 100 kHz.


– Consider how your speakers will be powered (voltage). If you’re using high output voltage speakers that require more than the standard 14 volts but less than 45 volts (for example), then you’ll need an amplifier with a voltage switch to accommodate the speakers.

Class A, B, D:

– Consider what class you’re looking for (A, B or D). Class A/B amplifiers are great for beginners because they typically cost less and can power your speakers just fine. However, if you plan on getting more serious about home audio systems in the future, then it’s best that you upgrade to a class D amplifier for better sound quality and power.

Class A/B:

– Class A/B class amplifiers are typically less expensive while giving you more power, but they also tend to run hotter than other classes. If your speakers require high wattage like 800 watts or above, it’s best that you stick with a class D amplifier for better sounding and efficient power.

Sound quality:

The sound quality of monoblock amplifiers is generally better than that of separate components such as an amplifier and pre-amplifier (receiver). This is because there is no “path of least resistance” between the amplifier and the speakers.

The power produced by monoblock amplifiers feeds directly into your speaker, which allows for a great deal more control over sound quality than receivers or pre-amplifiers provide.


– Consider the size of your monoblock amp in comparison to the space you have available. Many amps are designed with maximum sized heat sinks so they can dissipate heat properly during operation – if this is an issue, take measurements before buying one! The right fit will ensure that the amp doesn’t overheat or underperform.

Always buy more power than you need:

Always buy more power than you need When shopping around, always pay attention to the input power of each amplifier. Consider this example: if you have two 100 watt speakers and an amp with 400 watts, but your speaker’s peak output is 300 watts or less, then you’re going to end up overdriving your receiver!


Some amps have features that make them better than other amps. For example, many people prefer amps with remote subwoofer controls to those with a built-in equalizer. With a remote subwoofer controller, you can turn up the bass from the front of the car for more customized sound output.

Other useful extra features include safety shut-offs, RCA, subsonic filters and automatic turn-on capability. These extra features make the audio better as well as protect the amplifier.


The price of monoblock amplifiers varies greatly depending on the style, features and power. Monoblock amplifiers generally cost more than stereo amps because they are built with fewer components to ensure better sound quality. You can expect to pay $100 or more for a basic monoblock amplifier, while high-end units sell in excess of $2000 per unit.


– Consider the warranty offered by your amplifier manufacturer when buying an amp for your speaker system. Some brands offer lifetime warranties on their amps while others only cover them for a few years, so it’s important to know what you’re getting into before making this purchase!

Answer: The best car subwoofer amp to power two Infinity 1200 subwoofers is the Tesla T1500.
The Tesla T1500 is a 1,500 watt perfect for powering two sets of Infinity’s TN1212S powered subwoofers at once.

It features dual inputs, variable input sensitivity control, and has outputs to deliver over 1,300 watts continuous @ one ohm with an “ultra-low” THD+N of 0.03%. An excellent choice for audiophiles looking to take their system to the next level!


Answer: Impedance is a measure of how well an electric machine converts electrical potential energy into rotary motion.
Impedance ratings for electric motors include wattage and horsepower, as well as hertz (cycles per second) and revolutions per minute.

For many applications, the right motor is the one with the lowest impedance rating given the application’s demands for power and speed. For low-power applications such as battery-driven pumps or musical instruments, lower impedance ratings are generally not important to consider.


Answer: Bridging an amplifier is when you take the power from many channels and make it one. You can’t bridge a sub amp because they only have one channel. But you could strap them to another amplifier which lets you power up more.

Yes. In order for the new amp to sound the same, you will need a speaker with an impedance that is within 4 or 5 of your original amp. Try putting a resistor on the ears of your cabinet and see what happens. A 3dB-drop in output occurs when speakers are bridged this way because only half the energy from one amplifier goes into each load (speaker).


Yes. Monoblock amplifiers can power two subwoofers as long as the total power output is at least 400 watts.

A monoblock amp (also called “single-ended”) contains one amplifier circuit and transformer; the other amplifying part of a stereo amplifier, known as a “push-pull” amp, typically contains two such circuits and transformers for each channel.

Consequently, a mono amp might provide less power than a push-pull amp and be less efficient in its use of current from the electrical line to generate audio signals.

However, for installations where only one speaker requires amplification or simply higher sound levels need to be achieved with minimal distortion using thinner wires, monoblocks can be an attractive choice.

Two, four or five-channel mono amps are also made for use with component surround sound systems. These include separate circuits for each channel and the corresponding speaker so that there is no need for a receiver to provide amplification output.


A high gauge wire is not necessary for an audio signal. If in doubt, 16 gauge should be used in most cases. It’s important to remember that the overall impedance of a speaker and amplifier is usually much higher than 8 or 16-gauge wire can stand up to long term when the voltage starts becoming significant (150v+). It doesn’t make sense to use such low gauges for such low power signals. Result = blown speakers and amplifiers.

Generally speaking, the larger the speaker, and/or its power rating, the thicker the wire should be. A good rule of thumb is to use at least 14-gauge for speakers rated 100 watts or higher. For speakers, 40 watts and lower, 12 gauge is usually sufficient.

These numbers are only a guideline as you should always double or triple check speaker compatibility with the amplifier or receiver you are using.

Famous Monster Cable recently tested 16 gauge against their own lower-gauge speaker wire and found that there was no measurable difference in audio fidelity. That said, they do recommend 18 gauge for extremely long runs (e.g. greater than 50ft) and 16 for lengths ranging from 25-50ft.


Answer: A mono amplifier performs better at 1 Ohm because it can be tuned to deliver significant power with uniform quality. Two-channel amplifiers, on the other hand, likely have uniform power between channels but will usually not be able to take advantage of a lower impedance load and respond more quickly than one would like.


Answer: A/B Class amps will give you the best sound quality, so keep this in mind. D Class amps might not sound as nice but they don’t need to be installed and provide more power than A/B class models so there is a trade-off. One can audition both an A and B Amp to see if it’s worth what you’re giving up for the look of A or B quality.
