A car amplifier is an electronic amplifier used to increase the power of a sound signal generated by a radio, CD player or mp3 player. These amplifiers are designed for use in cars because they are built to withstand vibrations and produce louder sounds without distortion that could be caused by bumpy roads.


Amplification is the process of increasing the strength of an electrical signal. The amount of power obtained from an amplifier is measured in watts. If additional speakers are connected to the amplifier, each speaker will receive the same amount of power allowing for a more uniform sound throughout the car.


An amplifier works by taking a low voltage current supplied by the player and increasing its strength so that it can drive speakers which require much more power than the original voltage supplied by the player.

For example, if there is an audio signal of 1 Volt traveling through a wire which has resistance, it will only create 0.77 Volts across the wire after traveling through it for one meter (1V/0.77 = 1.3m).

This means that the speaker connected to this line will have to have an impedance of 1.3 ohms if it is powered by a voltage supply of 1V because the 0.77V now created across the speaker will not be enough to drive it properly.

A car amplifier performs this same function but does so much more effectively. It has large power supplies that are capable of delivering high current, usually up to several hundred amperes.

It also has a large transformer which is used to step up the voltage from the incoming supply and deliver it with high current across the speaker line. This allows for loud sounds at low impedances without causing too much power loss over distance as compared to smaller amplifiers built into player units.


Car amplifiers allow you to hear your audio more clearly and loudly than ever before. Whether you enjoy listening to the music on your mp3 player while driving, or if you need an amplifier for a sound system in a large commercial space, there are many different options to choose from when purchasing amplifiers.

Buying a car amplifier that suits your needs and preferences is an important decision, which is why we here at Focalprice provide you with the widest and most comprehensive selection of car amplifiers to help you find the perfect fit for your lifestyle.


Before you buy the best cheap amplifier for car, it’s important to do your research. We’re here to help you get started. Check out our guide below for factors that are commonly considered before buying any sort of amplifier.


The first thing you’ll need to do before buying an amplifier is to find out what you’ll need the amp for.

While it isn’t necessary to get a larger amp if you’re not using all of its channels, you should consider whether your speakers can handle certain wattages. If they can, then that’s fine – but if they can’t, it may be wise to look into a separate amplifier.


You’ll need to consider how much room you have in your car for an amplifier. In-car amplifiers are usually very compact, but some high-powered amps can be pretty big – so make sure there’s enough space before starting to look at amps!

If you do decide which amp you want, you can always find out how much space it takes up in your car with the help of our handy guide.


Car amplifiers are available in mono, 2-channel, and 4-channel options. You’ll need to decide what kind you need before looking at specific amps.

Mono and 2 and 4 channel options are primarily divided by where the speakers will be wired up – we’re talking about the number of channels. Mono amps have one set of speaker outlets for all the channels, while dual-channel amps typically have two sets of identical outputs.

4-channel amps (powered by 4 channels) and 5 and 6-channel amps (with five or six separate outputs) can also be found – but we won’t explain them here.


Amplifiers will often come with different impedances, at which their rated power is applied. Impedance is measured in ohms, and generally, speakers with higher ohm values will be better suited to high power output from an amplifier – even if it’s unreliable.

Ohm ratings typically vary between 2 and 8ohms, so this factor may also affect your decision in speaker choice.


An amplifier won’t do you a lot of good if you can’t plug it into your car’s electrical system. To make sure that your amplifier is compatible with your vehicle, check where on the bodywork the fuse box and battery are – as well as the kind of wiring harness you need.


If you’re planning on doing your own amplifier install check out this guide to ensure that you wire everything up properly. This is vital because an incorrectly installed amp can result in broken equipment – and sometimes even fires!

If you’re not confident with wiring up your amp, it may be wise to hire a professional to wire it for you.


Depending on what car audio application you have in mind, the wattage of the amplifier will vary. Some amps are rated at 40 watts RMS per channel – while others are around 100 watts RMS per channel.

If you’re just looking for a basic system to play at low levels, or perhaps use one amp with your car’s head unit, an amplifier that gives 40 watts RMS will be enough. However, if you want to blast volume while driving – you’ll need the higher wattage amps.


Amplifiers usually have a specific range of systems which they will work with. Make sure to check what your head unit’s system is – and if you’ll need an adapter cable to fit it properly.


If you’re looking at purchasing an amplifier, the number of speakers in your car will affect which kind of amp you end up buying. For example, if you have 4 speakers in your vehicle (2 fronts and 2 rears), buying a mono (single channel) amp will be enough to provide adequate power for them all.

If you’ve got 6 or more speakers in your car, however, you’ll likely need a 2 channel amp – otherwise, the sound won’t be equal across all the speakers. The number of speakers is also important for wiring up an amplifier correctly – so make sure to check this before buying!


If you’re planning on installing an amp in your dash, you’ll need to make sure that it can handle high temperatures. We’re not just talking about the summer – if there’s no ventilation into or out of your car, it will become hot even during winter.

Some amps come with a thermally controlled fan system to keep the internal components cool even in high temperatures, without making too much noise.


Amplifiers will typically come with protection features that stop them from being overloaded by your speakers – but it’s always good to check before buying.

For instance, if your amp is rated at 50 watts RMS, it won’t last long if you crank the volume so high that it’s giving out 500 watts RMS. This will damage your amp and could potentially cause a fire!


All the best amps on the market will usually come with an LED light to indicate that your equipment is receiving power. This comes in especially useful while driving at night – so you can see when your amp turns on or off while still focusing on the road!

The LED indicators also show voltage short-circuit or impedance mismatch, so it can be a good indicator of the health of your amplifier.

Sample Customer Review:

“Don’t know if the RMS is true for this amp because I don’t have a way to check it. I can say that I have it on 2 Planet Audio Torque 10’s listed as 1200w and 600w RMS in a myself built box(sealed) that is 1 cubic foot per speaker inside. I’m also using a HP 460w server power supply to run it and on full crossover with the gain at about 80% I feel like the cones are going to tear loose on the subs.

I built this box to use at work in a hot environment and it does get pretty hot after a few hours of running under this load but has not shut off yet. Have only used for a week and so far it’s great and will edit review if I have any problems with it.”

This keeps the amplifier from having to reproduce those frequencies, which would waste power and could cause damage to the speakers.

SWITCHABLE BASS BOOST – Bass boost gives you more control over your bass sound by allowing you to boost it at will. It’s not for increasing volume, but rather for adding more of a punchy kick in your music when needed.


  • Extremely easy to use
  • Can be controlled by remote
  • Inexpensive for what you are getting


  • The remote control does not have a good range

Sample Customer Review:

“Easy install and drives the 10” Rockford Fosgate in my truck good enough. The bass boost is a toggle switch from +0db or +18db. It would be nice if there was a range or another step or two. As it is, I think it sounds better off. The bass control knob is not very sturdy, but it works ok. Regardless, for less than $60, I’m happy with this amp."

“If you’re looking at this and it’s available (for $140) buy it! It’s class A-B so it has a more natural sound than digital amps. 50×4 seems to be a conservative rating as this powers my components and a 12” sub with ease. Gets HOT when pushed. Clean, clean, clean sound when used properly. This price is unbelievable. Considering buying another just to have…"

Sample Customer Review:

“Great amp for door speakers

I am pushing 4 6×8 type r and they sound outstanding. Like most name-brand amps, this was rated at 103 watts per channel at 2ohms. I was happy because while 50 is fine I did consider a higher amp to get closer to the 100 mark. I have the m500 for the sub and again glad I went with 2 separate amps instead of combined. Clean power = quality music.”

Sample Customer Review:

“Love the amp! I’ve never used a 5 channel amp. It’s nice to have full stereo and be able to adjust front to rear and side to side, since I didn’t have to bridge it. It’s rather large, about twice the size of the alpine I had.

The only problem I have with it is there are two rows of led lights that backlight the top of the amp that are pretty bright. I had to mount it on my sub box because of the size and the lights glared off of the back windows at night.

I couldn’t see out with my rear view mirror. After contacting Boss to see if there was any way to dim or remove them, Which there is not. I placed a couple of strips of black duct tape over the lights, problem was solved! I Highly recommend the amp for the sound! I’m an audiophile, not a thumper, but at 3700 watts it should handle anything you throw at it.”
