Buyer’s Guide for 4 Channel Amps

If you decided to upgrade your car stereo system with amps and sub, you’ve already committed to enhancing the listening experience in your car. Here I mention some points to remember while buying a 4-channel amp.

  • When choosing an amp, buy one that is more powerful than you need. Look at the R.M.S. of the subs and speakers. Adding extra power will boost the depth of the music.
  • Do not overload your Amp, and make sure it is compatible with the number of ohms you will be wiring it up.
  • Maybe your factory speakers are not compatible; pair the Amp with aftermarket speakers.

I will also tell you all about the size, R.M.S., impedance, power rating, and everything theirs is to know to have a fullproof and sweet-sounding system. Let’s start 


It is a crucial point to remember. You must match your speaker’s ohm (impedance) value or subwoofer with the amplifier. If you don’t, you may face issues. 

Sound Quality

You get the product, what you paid for. However, there are a few exceptions, which you will find on the list above. Typically some cheap brands don’t have the resources to try and test so many variables, so their audio quality would be weak.

A Class A/B gives a better sound quality than Class D; however, the difference is not that noticeable with the latest tech.


The size of the good 4-channel amplifier can be smaller than a class D. Either way, 4-channel amps are small. This gives you many options and flexibility in where you can install it.

The most common place to install the amps is under the seat or trunk. It’s good; these amps are small and won’t take up space wherever you put them.

Frequently Asked Questions 

What Is A 4-Channel Amp?

It amplifies the standard 12V voltage so the speakers, tweeters, and subwoofers can shine. As the name suggests, the 4-channel amplifier has 4 amplification channels.

The actual reason why it’s a good idea to pick these over others is that you will get a full range of sound. With the right 4-channel amp, you will unlock the perfect mids and highs, and this is what you want in your favourite songs.  

How much power do I need? (R.M.S. power ratings)

The amount of power required comes down to the speakers or the subwoofer. And we know subwoofers need much more power than speakers.

Power is mentioned in the manual. You get along with the Amp, so take the manual and see the R.M.S. rating for the speakers and subwoofers. It is advised to check the R.M.S. rating and not the max power because certain brands are known to exaggerate the latter numbers.

How many speakers can be run with a 4-channel amplifier?

You can run between 2 and 6 speakers with a four-channel amp. This comes down to the amp type, size, and wiring options.

Do I need a head unit to use a 4-channel car amplifier?

The 4-channel car amplifier only increases the power you send to the speakers. The head unit serves a different purpose. With a head unit, you can control many things, and it also offers pre-amp outputs.

Do we need a 4-channel amp for 4 speakers?
