Best Car Amplifier- The Ultimate Buyer’s Guide!

How far would you be willing to go so as to get your car at it’s best? well, when it comes to getting your audio system pumped up, one of the most important components may be an amplifier. Though it may be preinstalled in your vehicle already, the stock units are not necessarily what you should choose to be working with daily which is where we come in.

Today, we’ll be looking at what you should look into if you want to end up with an audiophile-grade car amplifier. Here’s a buying guide that will lead you on how to go about when shopping for the best car amplifier. Let’s get started right away, shall we?

What Difference Does an Amplifier Make?

You may be hesitant to go for an amplifier upgrade but before you change your mind in doing so, here are 3 major reasons to get an upgrade.

Boosts the performance of your upgraded Speakers

car speaker

The first upgrade most people will go for first in their audio system is basically the speakers; after all, if you really do want a good sound, you should go ahead and get more powerful speakers, right? The factory installed amp may not be enough to power up your new speaker which only leaves you with one option- going for an aftermarket unit.

The rule of thumb here is that the more powerful your speakers are, the better an amp you’ll be needing.

Improve the overall Sound Quality.

sound quality

You may not necessarily need new speakers to have an outstanding music experience in your vehicle and the trick may just be getting a good amplifier. The trick behind getting a good amp is that you will give your speakers a clean power source which will highly contribute to the way the sound will be delivered.

Gets the subwoofers working better.


A speaker is not normally enough for a good bass in most cases, right? Well, to get the best out of your subwoofer, you’ll need a reasonably high amount of power and amplifiers just so happen to give an optimal amount of power to your subwoofers.

Getting the Best Car Amplifier

Considering there are quite a lot of options to choose from in the market and it may be difficult to get exactly the amp that you need, here’s what you should pay attention to.

The Number of Channels.

It is important to know which configuration you’ll be needing. The number of channels basically indicates the number of speakers the amp can power simultaneously.

One speaker per channel should be enough but if you would like to install a subwoofer in a system that already exists then you should go for one with a one channel amplifier. On the contrary, if you’ve got more speakers, you can choose an amp with a higher number of channels.

The Power Rating.

Yet another thing to take into account is the power handling capability. Don’t be mean on the power if you want a good audio quality. The best thing to do would be choosing the speakers you need first then go ahead and select an amp which will supply enough power to the speakers as needed. It will be easier for you to decide the minimum power you’ll need for your speakers.

The power is normally expressed in watts per channel. If the power is lower than what your speakers require, you’ll probably end up with a distorted sound

Will it be Able to offer a Good Enough Sound Quality?

Yet another thing to take into consideration is the sound quality besides just the power rating, a lot more other things will determine how good the sound is.

An amp that will significantly improve the quality of sound will have, for instance an outstanding input sensitivity, filters for the high and low frequencies, a low impedance rating and a good frequency response among other things.

In order to get the best of all these, you should probably take a look at how the speaker is reviewed by other uses or even better ask for recommendations from an expert.


Car Audio Amplifier Instalation

DIY installation may be a little bit difficult since there’s a lot to be done starting with the installation location, getting the required wiring kits. If you’re lucky, you may have the installation kit provided for you. You could also refer to online videos that will conveniently guide you on how to get things done fast.

If you’ve done it before, you could go ahead and set it up yourself but if otherwise, it’s best that you seek the assistance of someone who’s done it or the aid of a mechanic.


Coming to the end of our review, getting an amplifier is definitely something you should consider as far as upgrading your car’s audio system is concerned.

Regarding on the configuration you want, you should go ahead and select an amp that will give you exactly the quality of sound you need. As for the installation, I’ve got to say that this is no easy task since if you go wrong on this, you may end up blowing up some of your audio components.

All in all, don’t sacrifice quality for price; if you want the best, you should be ready to spend a reasonable amount of cash on them.

A guide to The Best Car Amplifier in 2018

Even though every vehicle does have some sort of an amplifier, not all of the amps are external. You’ll get most of these built into the head unit and the truth is, most of these amps will not give you the boost you are looking for.

What defines an outstanding amp anyways?

Well, this is basically cannot be answered in one or two clauses. For instance, you may crank up the volume of your car audio system and notice some distortion despite having a good head unit and a set of speakers.

This is due to the presence of an underpowered built-in amplifier. Also, the power handling capabilities of your speakers have a big role to play but with the best car amplifier, how good your stock sound system will perform is going to blow your mind.

To simplify things as much as possible for you, we've narrowed down our research to 3 main things that you should look into when upgrading your amp or purchase your first:

  • check
    Is it compatible with your current sound system?
  • check
    Check for the power handling capabilities.
  • check
    The number of channels that suit you best

Is the amplifier compatible with your system?

In most cases, no matter what the manufacturers say about the car stereos, most of them do not exceed about 10 watts of RMS power output per channel.

With such a low amount of power, you cannot be able to conquer the noise on the road without the sound getting distorted. One of the best ways you can get to overcome this is doing an overall system upgrade- this has to include an amplifier mainly. You'll also include other sound processing gear that is exclusively meant to boot the overall performance of your automobile. At the same time, the interior will not lose the factory appearance.

So as to end up with amazingly clear sound quality, it is important to consider providing a signal that is not amplified by your amp. The best way to do this is going to a head unit that has got preamp outputs which sadly, you cannot get in most factory-installed head units as well as most of the aftermarket ones.

Whereas getting a new head unit with preamp outputs will solve this, it may prove somehow difficult to get one not to mention you’ll be spending some extra cash.

Rather than getting a new head unit, you can alternatively go for an amp with speaker level inputs. This will not only save you the hassle of doing a lot of wiring but you will also get a better sound than you would have when using an external amplifier.

Don’t go low on the power.

Power handling is one of the most important things to take into account as far as doing an upgrade to your present sound system is concerned. Regardless of whichever upgrade you are doing one thing always holds- always provide your system with the right amount of power.

So as to get the best sound from your head unit, most people end up picking out their speaker sets first then finding an amplifier that’s enough to power them.

 A speaker will normally have an RMS rating and this is normally represented a range- say for instance 10-60 watts RMS. The higher end of this scale represents the driving power the speaker will play to its fullest based on the manufacturer. 

Whereas most speakers are rated to take a lot more power than their rating, this cannot be so if they don’t get as much as ¾ of that power rating.

So, assuming you already have the aftermarket speakers with you, here’s what you ought to do:

First off find out their top RMS rating. If your speakers come in a pair, it should be easy since this will be the same in both of them. On the contrary, if the speakers are installed in different locations, go ahead and use the rating for the lower-powered speakers. You should then multiply that number by (75%)0.75 which is the minimum RMS the amp that'll work best for your set up should have per channel. Now multiply that rating number by (150%)1.5 since most speakers are able to operate way past their RMS; this is the max output channel you should want your amp to have.

At the same time, if you cannot find an amp that is small enough to handle the low power ratings, you can alternatively set your amp's gain low enough such that it won't have to attain its max power. This way, your speakers are guaranteed to be safe.

Moving on to the easy part:

2-channel amps

Most people seldom use their rear speakers which is why they go for the dual-channel amp. This is needed when you only need to power a single pair of speakers.

4 channel amps

Considering everyone has a different taste when it comes to setting up their sound system, you may want to gain the front-to-rear control in which case the best car amplifier is the 4-channel amp.

3 channel amps

In the case where you'd want to include a subwoofer, you can go for the 3-channel amp which handles a pair of speakers with the sub as well. You can also employ a 4-channel amp to handle the sub- simply bridge two channels together for the sub and let the remaining two handle the remaining speakers.

The 4-channel amp not only allows you to take care of the sub but at the same time allows for potential future expansions of your system. You can either add a sub in future or another speaker to your current music system.

5 channel amps

Powering the whole if your system from one package can conveniently be done with a 5-channel amp. This can take care of the speakers, more than one subwoofer and also leave room for the addition of other components.

If you may need to run 3 and 4-way systems, you can go for the 6 or 8 channel amps. These work well by dedicating each of the channels in the amplifier to handle the different drivers.

Tip: in some cases, an amplifier cannot always be able to handle the power capabilities of a subwoofer which is why there are the mono amps. These can exclusively be used to handle the subwoofer so that it is able to make use of an optimal amount of power to get to its full potential.

Setting up your car amplifier

Knowing the type of amp you need is not enough if you won’t be able to set it up as one with your system. The truth is, correct amp wiring is much more complicated than swapping your speakers or a head unit considering there’s no dedicated location meant for the external amp installation.

How about we move on to the amplifier installation guide right away?

First off, to get started, here are the basic connections you need to be aware of when wiring up an amplifier:

  • Audio input
  • Audio output
  • Ground connections
  • The battery power
  • Remote turn on

The battery power a remote turn on and the ground connection are essential when supplying power to your new car amplifier. First off, hook up the battery power cable to tot battery’s positive terminal directly. Considering this will be going directly to the positive terminal of the battery, you should go for a thick cable- most preferably 10 and 1/0 AWG through the specific cable gauge for the amp can be found in the manual that comes with the amp.

The rule of thumb when it comes to the type of cable is that the one you’ll be using to connect to the battery is what you’ll also use for a ground connection though this won’t be as long as the power cable.

For the remote turn on wire, you will need a thinner cable and in addition to this, it should only be long enough to get to your stereo from where you’ll be setting the amp up from.

The audio input and output should be easy since this only needs a speaker wire to get things done. RCA audio cables should be enough to do this conveniently. These cables are basically those with red and white connectors or red and black in some cases.

Getting the right components for amplifier wiring.

Even if you look the external car amplifiers online, you’ll notice that they do not come with wiring cables which means that you’ll be purchasing most of the components. To make things easier, you can purchase them as being part of a car amp installation kit.

Amp wiring

It’s important to know the length of wire you’ll need to run the cable between the car’s battery and where you are to install the amp. This can be under the seat, in the dash or at the rear of your vehicle. The same should also be done for the head unit so that you’ll know how long the remote turn on wire needs to be.

Speaker wiring

Lastly, go ahead and check what you need between the traditional speaker wires and the RCA cables; simply check whether your head unit has a line-level RCA output. If the RCA outputs are present, you’ll just need the speaker cables to hook into your amplifier given it’s got speaker level inputs.

Now that you already have your amplifier and have already listed down all you need to complete the installation, you’ll need to go ahead and hassle to purchase them. Speaker wires and cables are easily available and if you’re lucky, you can get them cut in the correct lengths. It’s always advisable to allow some slack in your wires and at the same time don’t have them being too long to avoid tangles.

Amplifier wiring kits for your vehicle.

Even though the car amplifiers do not come with any of the installation cables, you'll be forced to do the installation yourself.

If this is your first installation or you just want to get everything that’s required all at once without leaving anything out, then the car amp wiring kits ought to suit you best.

These packages basically come with everything you’ll need to do the installation conveniently on your own which saves you both the time and money it takes to get this done by someone else. Normally the basis on which these kits are categorized is by the gauge wire.

You can get the 10-gauge, 8-gauge, amp installation kits and know the type of gauge wire that you need to set up your amplifier. Besides just the gauge wires for ground connection and connection to the battery, you’ll also need to know whether or not you’ll need the audio input and output cables i.e. the RCA cables.

Will as much info as we’ve just mentioned in mind, getting the perfect car installation kit for you should be quite simple. All in all, here’s a list of the minimum components that should be contained in your amp installation kit:

  • The power and ground cables
  • RCA cables otherwise known as speaker wires
  • A remote turn-on wire
  • An in-line fuse and a fuse holder

Besides the above-mentioned equipment, here are some additional components that you should probably consider giving the first priority when shopping for a car amplifier wiring kit:

Here’s a little bit information that will definitely come in handy

Whereas setting up an amplifier isn’t as difficult as we probably thought it would be, you’ll want to give some thought where you’ll have the amp installed as well as how you’ll set up the wires. This is basically the tricky part considering that most vehicles do not come with a car amplifier pre-installed.

Regarding the measurement of the amplifier, you should take the measurement of the potential installation location as well as the length of the wires.

You could install your amp in any one of these places:

  • Under the seat
  • In the trunk of your car
  • Against the firewall of the passenger side.

Measuring up these spaces prior to placing your order will save you a lot of hassle.

Only choose from 10 of the best car amplifiers.

The low pass and the subsonic filter:

So as to ensure that you get the best bass, this amp comes with a low pass filter that handles frequencies between 50Hz and 250 Hz. If you though the low pass was everything, wait till you get to use the subsonic filter which handles even lower frequencies ranging between 15Hz and 55Hz

The MOSFET circuitry.

Now here’s something you’ll not be getting on just any car amplifier. This ensures that the amp is able to use the maximum possible amount of power without getting damaged. The MOSFET power supply gives you higher speed, a lower loss rate, lower noise and simultaneously delivers a cleaner and more efficient power with minimal distortion.

IC controlled circuit protection.

It's not every day that your amplifier will have this feature whatsoever. Considering that this one comes with a fully IC controlled circuit as well as a professional peak limiter circuitry, it is guaranteed to be distortion free at all musical playback levels.

A mono class-D engineering.

As compared to the typical class D amplifiers, the Mono RXD amps are quite ideal. This technology is referred to as optical coupler (OC)class gives your system a punchier bass than what you would get from typical class D amps. One major difference is the separation of the preamp input and output stage in the circuitry. It is also less susceptible to noise which occurs from the preamp inputs.

Our final take on the best car amplifier.
