If you’re looking for a good car amplifier for the subwoofer, then you’ve come to the right place. With all the options available today, it can be a little confusing when trying to choose which one is best for you.

So, I’ve put together a detailed guide that will help you choose the best car amplifier for subwoofer, based on your needs and preferences. In this guide, we’re going to discuss the different types of car amplifiers and their features, as well as help you choose the best one for your needs.

👉The Impact of Impedance on Car Amplifier Performance and Power Output

We’ll also focus on subwoofer amplifiers specifically since they are often the most important component in a car audio system.


A car subwoofer amplifier amplifies low-frequency audio signals, which makes it a perfect choice for adding powerful subwoofers to your car. It’s easier to install an amp with integrated amplifiers.

An amplifier in a car or boat can help a weaker signal become a stronger signal. You can use this to power speakers.

Almost every audio system has one, whether it’s a stand-alone component under your car’s seat, built into your car stereo, or in your home entertainment center. The best car subwoofer amplifier enhanced sound quality, unlike the built-in amp.

Sample Customer Review:

“Like many other amps it has a super small tendency to have a background noise. But I’m talking small, engine running and you need to listen for it and intermittently happens. Truly not amazing for the price and overwhelming quality of sound and power it helps project through my speakers.

Highly recommended and also works great if you only want to run a subwoofer as it has a bypass switch. Manage to also use OEM amp wiring with no issues or clipping.”



MOSFET Power Supply

A MOSFET is an electrical switch that allows the flow of electrical current. Always remember that the MOSFET is a transistor and the best way to think of a MOSFET is as a switch that allows the flow of current. The MOSFET is a solid state device that doesn’t require a heavy duty power transformer to operate.


The low level input is measured in the same way that the high level input is measured. A high level input is measured in kilowatt hours. The signals from your receiver to your amplifier are carried by both of them.


Subwoofers work by reproducing sound based on a number of different low frequencies. You can adjust the frequency and power of the bass to set exact sound specifications.


Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.


To adjust the gain control, which is used for adjusting volume, is to adjust the level of the audio signal that is coming from the receiver and going to the amplifier.

Sample Customer Review:

“Honestly I expected more than what I truly got. I originally got this amp to power 2 12” MA Audio’s. It powered them very s***tily. I ended up switching the subs out 2 12" kicker comps 500 watt in a 4th order band pass box (same box as the MASS) and it poweres them perfectly. The tuning on the sub is set up the same but compared to other boss amps the tuning doesn’t turn out as clean as I would like since it doesn’t seem as sensitive.

If you do the kicker set up you won’t have any problems. I’d honestly say a 3.5 out of 5 if I could but I can’t. IF YOU PUT THIS AMP DIRECTLY ON THE BOX PUT SOME RUBBER BEHIND IT. THE LED RIDDLE IF YOU DON’T!"

Sample Customer Review:

“I’ve had a boss 1150 amp for a couple years hooked up to the 2 12” terminator MTX’s. It’s done it’s job honestly as far as playing music, but it sucked the power out of my car and would overheat easily if turned up. I spent well over in 800-1000$ trying to fix my issues. Competition battery to fix dimming issues, the big three done with 0 gauge wire, high output alternator.

Nothing ever fixed the power issue until I got this. A quality amp that runs cool pushing the power it advertises, even more actually. The old one would burn my hand touching it too long, this one is cool as a cucumber. A quality amp, and quality wires (OXEGYN FREE COPPER, don’t fall for cca, it’s a waste of money) will solve your issues. Wish y’all better luck than I had, and thank you Rockford."

Choosing a speaker for a vehicle is never an easy decision. There are numerous factors to consider, including what kind of car you own, what your preferences are, the amount of money you have to spend, and a whole host of other considerations.

If you know all about considerations then skip this section and read below. But If you’re not sure where to start, there are a few things you should keep in mind when buying a new car audio system.


The first thing you should look at when you’re buying the best car amplifier for a subwoofer is the main reason you want one. Your reasons for wanting an amplifier may be different than someone else’s, so you need to figure out what will fit your needs.


If you just want to enjoy your music in your car and don’t care much about the way it sounds, then you may want to stick with an amp that offers a single channel. You’ll find a number of amps on the market that offer a single channel in a package that includes a subwoofer and a variety of speakers.

This is ideal for those who don’t want to spend a lot of money to get a subwoofer and speaker package, and who aren’t looking for the biggest and best subwoofers available. It’s also a great option if you have to use your vehicle’s factory speakers, as most car speakers are set up to amplify a single input.

If you’re looking for a better sound from your car’s speakers, however, then you’ll need to upgrade your amplifier’s power, channels, and possibly the wiring and setup.


If you have a small car with limited interior space, and you want to install a subwoofer in a convenient location, you may have a difficult time finding an amplifier that’s big enough for the job. In this case, you may want to invest in an amplifier that has a smaller box.


The first thing to think about when shopping for a car amplifier is how much power it provides. In general, the more the better. That being said, it’s important to understand your vehicle’s current power. Some cars, such as the Honda Accord, have a fairly weak engine, which means the amplifier’s maximum power needs to be limited.

Other vehicles, such as the Ford Mustang, are known to have some seriously strong engines that produce more horsepower than any other car on the market. Therefore, you need to ensure the car amplifier you choose is capable of delivering sufficient power to the vehicle’s speakers, even when the engine is cranked to maximum.


Ohms refers to resistance, but in the case of a subwoofer, it has to do with the resistance of the driver itself.

In a typical amplifier, the driver is a solid piece of steel with a small diameter, and the sound waves cause the steel to vibrate, which is then translated into an amplified sound.

In the case of a subwoofer, the speaker itself is the driver, and the driver is usually much smaller in diameter than the steel used in an amplifier, so a much larger amount of current is needed to drive it.

So if the sound waves are pushing a large amount of current through the driver, the result is an amplified sound. If, on the other hand, the sound waves are pushing a smaller amount of current through the driver, it may cause the amplifier’s electronics to overheat, which will likely shut down the amplifier.

That’s why subwoofers are usually designed to handle a certain amount of current, and if the current is too high, the amplifier will shut down.


This is measured by how well the amplifier tracks or resists any changes in current (i.e., resistance). The amplifier’s ohm stability is good, meaning that it resists changes in current well.


Mainly there are 4 classes that are used in Car amplifiers.


Class A amplifier is used for the front two channels. This type of amplifier is capable of producing more power and driving the two front speakers. These car amplifiers with excellent high-frequency response have extremely accurate output, and they don’t have crossover distortion.

Class A car amplifiers may be large in size, a little bit heavy in weight, and maybe more expensive than other classes.

However, it is not capable of driving a single subwoofer. This type of amplifier can produce more volume and therefore requires more current (watts) from your source.


Class B car amplifiers offer decent quality audio output and these are more efficient than Class A amps. But these amps are expensive like Class A.

Class B amplifier is usually used for two rear speakers. The most common type of amplifier for this application is the 4 channel class B amplifier. Class B amplifiers provide enough power for two rear speakers and usually only enough power for the front speakers.


Class AB car amplifiers have Acceptable crossover distortion levels and these are also more efficient than Class A amps.  But these are also a little be expensive.

Class AB amplifier is commonly used for rear speakers and sometimes for front speakers. This type of amplifier can use any number of speakers or subwoofers. It will also use a speaker wire to connect all of the speakers.

Most manufacturers only allow for three wires. One of these wires should be red, one yellow and one blue. The green ground is optional.


Class D amplifier is the most sophisticated type of amplifier. It is used for high power applications. It has a low power drain. This type of amplifier is the most sensitive to distortion, so make sure you have one of these amplifiers if you plan on using a subwoofer.

These Class D car amplifiers Generate very little heat, these are smaller in size, affordable in price, and far more efficient than Class A amps.


When shopping for a car audio system, there are two different options you have to consider — two-channel and four-channel. Most manufacturers recommend the four-channel option, because it offers more control over the sound quality, and gives you the opportunity to change the level of the bass and treble for different music tracks.

However, in some instances, this may not be the case. If you have a newer car, and the car manufacturer has built a sound system into your vehicle’s dashboard, you may not need to worry about having a four-channel system. It totally depends on your choice of listening now or in the future. But experts recommend that it should be maximum because you may expand channels in the future.


Car audio systems are designed to run a specific wiring harness, so it’s important to know your car’s model, year, and manufacturer. You can find this information on the car amplifier’s packaging or by calling the manufacturer’s customer service department.

Once you’ve figured out your car’s wiring requirements, the next step is to decide whether you’ll be wiring the amplifier directly to the battery, or whether you’ll have to tap into the existing wiring. If you have the luxury of a factory installed amplifier, then you can skip this step.

However, if your vehicle is a new model or a custom build, it’s vital to have someone wire it correctly so that the amp will operate properly and your speakers will sound good.


Some of the car amplifiers on the market today will have a dedicated RCA plug for speakers. However, many will require you to install a bridging cable, as they don’t come equipped with the proper wiring required to run a speaker.

Before you buy a bridging cable, make sure you know what it’s for. It’s usually used to provide a shortcut between two points, and you’ll often find it connected to a CD player and/or a radio, along with a subwoofer.

Compatibility The last thing you should think about when you’re buying the best car amplifier for subwoofer is what kind of amplifier will work with your car’s current wiring setup. If your car is using speaker wire, then you’ll want an amp that comes with a standard speaker level input.

If you have a car with an aftermarket head unit, then you’ll want to ensure that the amplifier you buy will accept your unit’s high level output. You’ll also want to check the amplifier’s specs to see if it’s compatible with your vehicle’s wiring, as there may be different setups that come with different wiring.


Depending on your particular car’s type, and what your preference is, you may find that the amplifier has multiple high-level inputs, such as an optical input, coaxial input, and others. These are great for connecting your smartphone or MP3 player to the amplifier. Make sure you’re aware of what’s available on your model before purchasing, so you know exactly what you need to buy.


When you purchase a subwoofer, you should always pay close attention to its maximum output level and speaker level inputs. For instance, you may need to know how much power the sub can handle so you don’t run it into the ground. If you have more than one speaker, this could also be a problem.

If you’ve got a high-powered amp, you may not be able to play more than one speaker at a time, so you’ll need to know the max power of each one. Some car amplifiers will have a volume control at the base of the unit, while others will have a separate control for each channel. Either way, it’s important to know what the recommended maximum volume level is for your vehicle.

It’s important to keep in mind that most car audio systems are designed to be used in conjunction with a subwoofer, so you’ll need to make sure you have the proper size subwoofer for your vehicle. To figure out what’s going on, it helps to understand what’s happening when a sound is played.

For example, a “full power” signal may take more energy than a “50 percent power” signal, even though they are the same volume. It’s because the higher the volume, the more energy it takes to create a sound.

The subwoofer uses the least amount of power as the output level, so if you were to have a full-range amplifier and you needed 100 watts to play your music, that’s what you would have in your subwoofer. But if the output level is less than 100 watts, you may be putting more power in your amplifier than you can actually handle, which may damage the amplifier.


What this means is that you need to know the power handling of each individual speaker in the system. If you have two or more speakers that require more power than the amplifier can provide, then you’ll need a subwoofer that’s capable of taking some of the excess power.

Some amplifiers will shut down if the speaker level input exceeds the amp’s power handling limit, so it’s important to check the manufacturer’s specifications.

Also, if you have a stereo setup, it may require the same amount of power as a single system.


If you’re looking for a subwoofer that has a good bass response, you’ll want a subwoofer with Digital Signal Processing (DSP). This process takes the sound wave, breaks it down into its fundamental frequencies, and then plays the different frequency ranges separately to achieve a more accurate reproduction of the original song.

The subwoofer’s DSP can enhance the low-frequency response of the sound waves so they sound more authentic when played back through headphones or speakers.

It’s important to note that there are several types of DSP, and a subwoofer doesn’t need to use any type of DSP to get the results you want.

However, many manufacturers claim that using their subwoofer’s DSP can help produce deeper, fuller sound, but you can easily determine whether or not the claim is true just by reading the manufacturer’s specs.


The low-frequency response of a car amplifier is measured by how loud it can be at the specified volume.


The high-frequency response of a car amplifier is measured by how quiet it is at the specified volume.


The midrange frequency response of a car amplifier is measured by how “full” the sound is.


The bass frequencies (bass), mid-range frequencies (mid), and treble frequencies (treble) are each measured using a frequency response graph.


This is measured by how “damp” or “tame” the sound is. The damping factor is the ratio of the amplitude of the sound to the amplitude of the reference sound.


This is measured by how many sounds, harmonics, or overtones the amplifier produces.


This is measured by how much of the music or source is being played through the amplifier.


How big is the wire going to your amplifier? Copper wire is measured in terms of gauge, which is the thickness of the copper wires.


How big is the speaker wire going to your amplifier? This is a matter of gauging, which is the thickness of the wire.


Some people prefer to have the amplifier near the speakers, whereas others like to have it closer to the subwoofer. This is usually up to you, but it’s important to remember that it’ll take up more space and add to the installation hassle. The selected amplifier should be easy to install.


If you don’t need to spend a lot of money to get a subwoofer and speaker package, and you’d like to try one of the larger models on the market, you may want to consider a more expensive amplifier that will give you more power and a better sound.

However, if you need to keep your budget in mind, you may want to look into a cheaper model that gives you a basic system with a smaller subwoofer.


Buying an amplifier that includes a subwoofer and a speaker package is a big commitment, as you have to make sure you’re buying the right equipment for the job. There’s no doubt that this will cost you, but it’s important to find an amplifier that comes with a warranty from the manufacturer that covers everything from the speakers to the subwoofer.

If the amplifier you’re buying has a limited warranty, you may want to look for a model that provides you with a longer warranty than the model you’re buying.


A good car amplifier must be durable, efficient, and affordable. But you should make sure that the amplifier you get is CEA 2006 compliant and fits in your vehicle. A car amplifier with CEA 2006 compliance ensures that your speakers don’t exceed the maximum SPL level of 100dB when playing loud music. This is the official definition of a compliant car amplifier.

The CEA (Consumer Electronics Association) standard was established in 2006 and requires all devices manufactured after 2006 to be CEA 2006 compliant. This means that CEA 2006-complaint amplifiers will deliver sound at lower volume levels, compared to non-CEA 2006-complaint amplifiers.

In conclusion, when you are shopping for a subwoofer for your car, you will find that there are many options available. However, it is very important that you should know what you want before you start shopping.

A good subwoofer will have the ability to handle a wide range of frequencies and power levels, and will also be able to produce a deep bass sound. When you are looking for a subwoofer, it is important that you know what you are looking for.

If you want to buy an amplifier that’s going to deliver the most powerful sound for your subwoofer, then look no further than the Polk Audio PA D5000.5.

An amplifier is a device that amplifies a signal. It amplifies electrical signals and converts them into audible audio signals.  On the other hand a subwoofer is a device that is used to reproduce bass frequencies.

impedance is a measure of the “load” an amplifier will sense on the output of a subwoofer. It Depends on the impedance load, an amplifier will put out different amounts of power.


MOSFET is the abbreviation for metal-oxide-semiconductor field-effect transistor. It is a field effect transistor with a MOS structure. The MOSFET is typically a three-terminal device. Gate, Drain and Source terminals are typically present in such a device.

MOSFETS are semiconductor components mostly used in switching applications. They’re characterized by high voltages and high currents. Their higher efficiency and higher switching capacity at high speeds make them the optimal choice for power supply design.


It is a type of metal-oxide-semiconductor field-effect transistor (MOSFET) that can switch large currents. Power MOSFETS uses a vertical structure with source and drain terminals on opposite sides of the chip. The vertical orientation eliminates crowding at the gate, allowing for larger channel widths.
