Sample Customer Review:

“I am using this to drive a subwoofer in my Travel Trailer. I have tried it into 2 ohms, 4 ohms, 8 ohms and also into an oddball that burned up its amplifier that measures 29 ohms. That amp just powers through. I have to put the gain way down or it would make the 15 inch sub destroy my trailer.

Only about 10 hours on it so no real look at long term yet. So far I am not really stressing it at all so I think it will last as long as I do. It could be improved with some additional markings on the settings dials to at least indicate approximately where various frequencies are. You have to think in logrythmic to make guesses. I will have to dial in settings once I have the whole HT done.”

This guide is from basics to advance factors, if you have any confusion to consider all factors then no issue, just remember the most important points according to your requirements.


It is important to consider the purpose to buy a car amplifier before purchasing one. For example, if you need better sound quality from MP3s and want the sound system to be loud enough for a party of 5-6 people in a small room, then it makes sense to purchase low watts budget car amp.

However, if you need to listen to loud music for a group of 10-12 people in a large room, then purchasing high wattage budget car amps is the best choice. You can also consider power subwoofers or satellite speakers with the amp. Power subwoofers are an alternative to buying just an amplifier for better sound quality.


The sound quality of the best budget car amps is excellent due to well-designed circuitry and better grade components. They produce crystal clear sound even at high volume levels. The bass response is fantastic with excellent clarity and detail.

These amps are able to handle maximum power without any distortion or damage to the audio system. A budget car amplifier with strong and flat bass and high frequency will be suitable for music lovers.


If you want to connect 2-3 speakers and a subwoofer, then the best budget car amp is offering 4 channels. If you need more sound sources like 3 pairs of headphones, an FM radio tuner, and iPod control, then go for 5 or 7 channel amplifiers.


The amp type you choose for your amplifier should be based on the overall quality of music that you desire. Class A/B is used in most car amps because it has a high dynamic range and better sound quality.

Class D amps¬†are used in budget car amps because it dissipates less power than A/B models. Class D is also more efficient than the¬†class A/B amplifier¬†and that’s why they drain out less battery power when running.


1. Mono or single channel amplifier: the mono amplifier is the simplest form of car amplifier. The output power of each channel in a mono amplifier is equal to 1/N, where N stands for number of the channels.

2.¬†2 channel or two-channel amplifiers: In a two channel amp, each channel’s output power ranges from 1/2 to 2 times of the power in the mono amplifier. For two channel amplifier, each channel’s output power is equal, and they share a common ground wire (if there are more than two channels).

3. Multichannel amplifiers: There are four types of multichannel car amplifiers; 4-channel, 5-channel, 6-channel, and 7-channel amplifiers.

4. channel amp: each channel in a 4-channel amplifier can have an output power from 1/4 to 2 times the power in a mono amp. In a multichannel car amplifier, a common wire is used for sharing between two channels at a time. If there is a left and right channel in a two-channel amplifier, there will be 4 channels in a four-channel amplifier.

5. channel amp: each channel in a 5-channel car amplifier can have an output power from 1/2 to 2 times the power in a mono amp. In such multichannel car amplifiers, there is no common ground wire among all channels.

6. channel amp: each channel in a 6-channel amplifier can have an output power from 1/4 to 2 times the power in a mono amp. If there are left, right and rear speakers in a three-channel amplifier, there will be 6 channels in a six-channel car amplifier.

7. channel amp: each channel in a 7-channel amplifier can have an output power from 1/2 to 2 times the power in a mono amp. In such multichannel car amplifiers, there is no common ground wire among all channels.

COMPACT DESIGN: Compact design is a very useful feature if you want to install your best budget car amp in a small space. You can choose from a variety of compact mini amps that have low power ratings and dimensions that match the interior of your vehicle. These best budget car amps also support low impedance subwoofers and high power speakers.


The next thing to consider is how many speakers you have and what size they are. Speakers that have a higher power rating produce better sound but require more amplification which means that buying a few good ones can be expensive compared to buying cheaper 4 or 6-inch speakers that will not give the same quality of sound.


If your car doesn’t have the space for an amp under the seat or behind the headrest, then there are several slim-line models that will fit into tight spaces while still providing plenty of power to your speakers.


Price is the first thing I would consider before buying a budget car amplifier. If you know that a friend or a family member has an old one lying around then ask them if want to sell it since they could be very cheap and in about the same shape as new ones.

If you do not have any luck there then check out online stores that offer a wide variety of products and models with a large inventory that is constantly changing.


Another consideration when buying a budget car amplifier is your stereo head unit. The type of stereo system you have determines the type of amps needed in order to get the perfect sound quality for certain areas such as speakers, subs, or even tape decks.

For example, if you have a 2-Channel amp then this is needed for just speakers since it has to be used with either one or two small speaker set-ups. If your stereo system only has 1 RCA preamp output then it means that in order to get sound quality in aux inputs you have to have an external amplifier that comes with the line out.


You should consider Bridging ability before buying the best budget car amplifier. You may not know what audio bridging means but this feature allows for an amp to power up multiple speakers in different zones which will allow you to have much more control over your sound system.

The circuit overheats, power overload and speaker short circuits are the most common protection circuit in budget car amps. Better quality budget car amps have these protections to protect your valuable system from damage due to voltage fluctuations or electrical problems.


Better quality budget car amps have MOSFET transistors for better sound quality. These transistors are more powerful and efficient than ordinary transistor units. You can expect a better bass response even at high power levels without overheating.


Crossovers filter out high and low frequency sounds from speakers. They help to prevent your amplifier from overloading due to too many bass signals. Manufacturers have included built-in crossovers with better quality budget car amps for smooth sound distribution at all volume levels without distortion.

These built-in crossovers help you to protect your speakers from damage due to overloading. The adjustable crossover frequency features are useful to set the subwoofer cut-off point without affecting mid-bass.


The power ratings of the best budget car amp should be considered while purchasing one. The wattage of the amp is divided into low and high pass filters, subsonic filters, and type of amplification (class A/B vs class D).


Power rating indicates the amount of power the best budget car amps can handle without getting damaged or overheating due to load fluctuations and high volume levels. Higher sound output requires a higher power rating for better performance. It is important to look for an amplifier with rated power that matches your speakers and the acoustic space of your car.


The low pass filter for a subwoofer is used to cut the lower frequency signals coming from full range speakers. On the other hand, the high pass filter of the best budget car amp cuts out all bass and low frequency signals sent to tweeters (treble).


This filter is used to protect the speakers from high bass notes. If you play music with deep and powerful bass, then it may damage your speaker cones because of too much sound pressure. You can prevent this by adding a subsonic filter to the amplifier circuit.


Wiring your amplifier to¬†car speakers¬†is not difficult. If you are able to connect the components of a home stereo system, then it shouldn’t be a problem for you. It may vary from model to model and some models have 3 channels while some have 4 channels. The manufacturer’s guidebook will be helpful for you to wire the amp to speakers and subwoofers.


Wiring harnesses are a great feature that allows you to plug and play with some best budget car amps. They have color coded connectors for better compatibility and easy installation. They also allow you to remove any unused inputs if not needed. These wiring harnesses make the installation process as easy as possible.


The driver is a small circuit board that takes the input from the pre-amp and boosts it along with power amplification before sending it to the speaker. Get an amplifier with at least 12 dB/octave, which will provide you with excellent low frequency response for music clarity.


The lowest noise specifications amplifier will help you to play good quality music without raising the volume too high. If you want better sound even at low system volumes, then go for a budget car amp with lower THD+N ratio.


Noise suppression technology is useful to suppress the audio signal even at high current levels. It allows you to play your audio system at full power without overloading or damaging it due to voltage fluctuations or electrical problems. You can use this feature with subwoofers to get a punchy sound.


If your budget car amp has a noise isolation system, it will filter out background noise for better sound quality. The output power of the amplifier won’t be affected even if there is any noise in an electrical system. It also helps to prevent alternator whine and light dimming.


For better sound quality, you should avoid budget car amps with high distortion. The distortion rating of the amplifier should be less than 1%.


A good budget car amp has a durable circuit, sturdy wires, and an aluminum heatsink. There are many models of the best budget car amps with low noise specifications from lead free RoHS compliant components. The weight of the amplifier should be less than 10 lbs or 4 kg. It will help to install it easily.


A best budget car amp comes with good quality RCA cords, remote control, and a warranty. Better installation accessories will help you to set up the system easily. If there are fewer accessories in the package, then you can purchase them at a reasonable price from outside stores.


You have to buy the best budget car amp, considering the fuse rating of your car. The Fuse Rating should be within10-15% higher than the battery charging system in your vehicle.

Always check the current ratings of factory installed accessories and replace them if necessary before purchasing an amplifier. This will help you to avoid blowing fuses frequently.


Speaker level inputs mean that the amplifier is compatible with factory normal, premium, and base model speakers. These amps can be installed easily without removing factory audio system. While Line level means that the amp is compatible with aftermarket head units only. They have special outputs for line level signal connection to the amplifier.


If you want a budget car amp with pre-amp out signal for adding a subwoofer in the future, then buy an amp that supports Graphic EQ control. A few models of budget car amps have this feature to enhance sound quality and increase volume along with adjustable crossover frequency. They are good for those who have factory speakers and want to add a subwoofer for deep bass without changing the head unit.


In input attenuation, you can control the amount of output voltage from the amplifier so that it doesn’t overdrive your car speakers. The better quality budget car amps come with 4-6 dB of input attenuation to avoid sound distortion at high volume levels.


If your unit is compatible with an FM tuner, you should buy an amp with tuner output. This will help you to connect the subwoofer amplifier directly to the head unit via speaker level inputs without cutting any wire. It will also help you to play the sound on both speakers and subwoofers.


Budget car amps have a special resistor connected to the output terminals to limit speakers from over-excursion. They also provide thermal protection to the speakers. Better quality budget car amps have this feature for clean bass sound at high volume levels.


Better quality budget car amps include premium components like large transformers, extra-thick circuit boards, and oversized power supplies for better performance. These features make the amplifier robust and reduce possible damage due to voltage fluctuations or electrical problems.


Better quality budget car amps have premium connectors with high durability for better reliability and long life. The low impedance design of these connectors reduces wear and tear due to heavy current flow. They can sustain high signal levels without any distortion.


Better quality budget car amps include better grade components like top of the line resistors, polypropylene capacitors, and more powerful magnets for a clean sound. They also have oversized heatsinks for better thermal management and maximum power transfer from the audio system.


Preamp outputs are useful to send an audio signal from the amplifier to a subwoofer or another amplifier for better sound quality at all volume levels. Preamp outputs have low impedance and can handle maximum current with minimum distortion, which is very good for long term reliability.


Top mounted controls are easy to access in some best budget car amps. They are made using high quality materials for a better life and lower power consumption due to less contact resistance.

These controls include bass boost knobs, signal inputs, crossover frequency knobs, preamp outputs, and more that you can access on the top face of the amplifier.


The frequency of Bass Boost is variable and adjustable in some best budget car amps. This feature will help you to increase the output power at maximum audio levels without overheating or damaging your audio system. You can adjust it with an RCA-type bass knob or remote control.


A bass boost control knob is a good feature that allows you to enhance the sound quality at all volume levels. This knob has a central frequency offset and varies from 0-18 dB in many best budget car amps. It starts to work when the volume level reaches 40 Hz. You can use this feature in low bass notes to get a punchy sound.


This feature allows you to connect multiple amplifiers in parallel with your car stereo amplifier. It gives you the option to link your audio system components like subwoofers, tweeters or mid-bass drivers easily without any difficulty. This feature allows you to upgrade your bass system with ease.


Amplifier gain control is another useful feature that adjusts the input signal for compatibility with the output stages of the amplifier. Gain controls are generally used to match low level signals from factory car systems, head units, and other components. They allow you to maximize sound quality with balanced sound levels.


Chassis mounted car amps offer better vibration and resonance control than normal amplifiers. They use thicker and more rigid metal enclosures to reduce noise, which is good for your overall audio system performance. Thicker materials can handle more power without getting damaged or distorting the audio signal.


A Standard RCA input is an analog audio input that carries a single channel signal from your car stereo system, MP3 player, or any other device to the amplifier. They use low level speaker wires because they have lower power ratings and lesser current handling capacity. Standard RCA inputs can be used to connect a subwoofer or low power speakers to the best budget car amps.


A signal sense feature in some best budget car amps automatically detects incoming audio signals when the amplifier is turned off, so that it can start playing music when you turn on the car stereo. This is a very useful feature for people who are looking to save battery life in their vehicles.


Passive and active inputs on some best budget car amps may be used interchangeably. Passive inputs are usually found in the front end of the amplifier for speaker level signals, while active inputs are placed closer to the power source for high current audio components. These features help you achieve better sound quality with a more powerful system.


Last but not least, be sure to carefully review anything that can give you extra signs of quality such as an indicator light that tells you when the amp is working, a protective cover to prevent the amp from overheating, and any other special features that can help you to protect your investment.

The conclusion is pretty simple: if you stick to a budget then it’s unlikely that you will find premium quality¬†car amps for cheap¬†but there are decent models out there. The key is to do your research so you can avoid buying low-quality models that are not economical in the long term.


One of the most important things to consider before buying a budget car amplifier is the weather and climate you will be in because this determines if you need an amp with speaker level inputs or RCA pre-outs. Another consideration when buying cheap car amps is the warranty length and customer support quality that comes with it.


It is also a very important factor to consider when purchasing a car amplifier is the speaker configuration. A 2-channel amp can power two speakers, while a 4-channel amp draws from four speakers.

Some models have¬†high and low settings for the channels¬†if you don’t want to use them all, or a switch that changes how the channels work.


The Next thing you should consider before buying the best budget car amplifier is its manufacturer specs. Always check if an amp has a CEA-2006 certification since this means that the manufacturer will have to provide more accurate and realistic ratings for power and size in order to be allowed to put these numbers on their product packaging.


CEA-2006 standards are set by the Consumer Electronics Association (CEA) which is “a not-for-profit, international trade association representing more than 2,000 consumer electronics manufacturers and retailers.” They used to allow companies to exaggerate their claims about the power of car amplifiers but now all specifications must be accurate.


It is always a good idea to read customer reviews to see what experiences others have had with a product before making a purchase. Reviewers will often list the pros and cons of an item, as well as any features that stood out or failed completely. You can also find expert reviews online from reliable sources that can help you make a decision.


The next thing to consider before buying the best budget car amplifier is its warranty length and customer support quality. Even if you find the cheapest model out there it can be more worth it to spend a little bit more if the manufacturer is well known for its great customer service in case there are any problems with your amplifier.


The most efficient car amplifier available today is the Class D amplifier. These amplifiers are able to achieve an efficiency rating of 95%, meaning they don’t produce much heat and don’t require cooling.


When you’re shopping for a budget amplifier, it’s important to keep a few things in mind. You should be aware that the least expensive amps are not going to be as good as the more expensive ones.

However, you can still expect good quality and performance from a budget amp that has the features you need and sufficient power, as long as it has good buyer reviews.

It’s important to remember that many buyers have unrealistic expectations of budget amps and leave negative reviews, so it’s always a good idea to read more reviews and look for patterns before making a decision.

Also, budget amps often use “peak” power ratings for sales purposes instead of continuous RMS power or CEA-2006 industry-standard ratings.

If your budget allows, you can always add a second amp later. When purchasing your amp, it’s a good idea to get a decent quality amp wiring kit to save time and shipping costs.

It’s important to keep in mind that budget amps are not designed in the same way as the big name brands that cost more. However, if you’re on a budget, you’re on a budget and that’s okay. Just make sure to keep your expectations realistic and prioritize the features you need.

1. Do I Need a Car Subwoofer Amplifier?

In a word, YES! A car subwoofer amplifier is not only useful and effective in producing sound waves that feel like they shake your entire car, but it also helps improve the overall power of your speaker system.

Subwoofers on their own can be underwhelming; you really need an amp to make your subwoofers shine and push them further toward their performance limits.

2. How much power does a car’s speaker system need?

Answer: For the bass, it should have at least 50 to 200 watt RMS of power. But for other audio ranges, 5 watts is enough to get the audio function working. The higher the voltage (RMS), the more efficient the speaker system will be when playing at louder volumes.

3. What does amplifier power rating mean?

RMS stands for “root mean square.” It is a mathematical term that describes the continuous power output capabilities of an electrical device.

In other words, it’s the amount of power an amplifier can put out without overheating and shutting down. The RMS power output specification of an amplifier is usually expressed as wattage (i.e., 300 watts).

But it can also be expressed as voltage (i.e., 60 volts). The RMS rating of an amplifier is always lower than its peak or maximum power output rating, which technically is the maximum potential instantaneous power that an amplifier can deliver to a speaker.


This really depends on what you are using the amplifier for. Most subwoofer amps will have between one and four channels (Channels 1-4).

A 2 channel amp is typically used for powering a subwoofer only, while three to 4 channel amps are multi-purpose type amplifiers that can be used to power front or rear speakers as well.
