The Best Car Amplifiers for The Money Buying Guide

When it comes to purchasing a high-quality audio system or amplifier, literally, there are limitless factors that you might need to consider. For instance, you need to consider RMS power, DBS, installation, controlling features, and anything in between these factors.

So, we have piled up all the factors in a zippy.

The Number of Channels for The Amplifier

You will find from a mono-channel amplifier to the highest six-channel amp in the market. So, things get a bit dubious here.

Mono channel amps are also known as D-class amps. It is ideal for those who want higher sound output. The trade-off is higher distortion.

The dual-channel amp connects with a subwoofer along with the two speakers, So you get a fantastic musical experience. And lastly, if you want all premium services in the same pack, purchasing a four-channel amp is recommended.

RMS and Max Power

It would be best if you prominently considered both outputs. Max output means the overall capacity of the amp to handle the highest audio output power in bursts. On the contrary, RMS refers to the amps’ ability to handle a continuous output at one time.

Ideally, both need to be higher so you can get better output.


The ohm of an amplifier is directly linked to the power output of the unit. Most standard amps come up with 1 ohm, 2 ohms, or 4 ohms capacity. However, some costly and high-end models consist of 8 ohms.

As a rule of thumb, a higher ohm means better output and crisp sound. However, an amplifier with higher outputs also requires more wiring, so keep an eye on it too.

Amplifier Size

Ideally, you get two alternatives for a car amplifier when it comes down to size. Some amps are so small that you can fit them quickly under the seat. On the contrary, the larger ones can take up to half of your car space.

Also, the size might be linked with power output and other features.

Control Panel

The amplifier control panel is of two types- the front panel and the rear panel. While both of these are good, you should consider one with an intuitive controlling facility.

Also, some unit offers a remote to control the bass and frequency output, which can be an excellent addition if you get one.


With the sheer advancement of technology, getting the best car amplifiers for the money has become a breeze task these days. You only need to consider the power output along with the channel requirements so it fits your car.

We sincerely hope that our buying guide has revealed the secret recipe for choosing the appropriate channel numbers and power output (RMS and max power) to help you in the cause. So, why not enhance the car audio experience to the next level?

Go and grab the one you liked most in our review- happy music & happy driving.


How do I install my car amplifier?

If you get a larger amp, placing it underneath the car can be your last option. However, if you own a compact amp, you can mount it on a trunk.  For the stashing, first, get a proper wiring kit for the amplifier with accurate gauging. Carefully hook it on the truck instead of bolting it permanently.

Thus the vibration of the amplifier will cover up the car vibration and lots of issues. It can be a real and ardent headache to find the car’s performance. Also, avoid mounting the amp upside-down, as it can trap the heat inside, causing inconsistency.

What are the best car amplifier brands?

There are several amplifiers for the car out in the market. However, not all of them maintain quality and consistency in performance.

So, we investigated profoundly and found that Rockford Fosgate, Kenwood, and Boss Audio are the three top-tier amplifier brands in the market. We also should mention Kicker, which can be worth investing in for cars.

What is the primary role of a car amplifier?

Most car stereos have a limited audio output. Thus, a car amplifier takes the small audio signal from the car audio system and uses an electric signal to boost the low signal into a much bigger one. So, you get higher sound output with filtered clarity.
