Best Competition Grade Amplifiers Buying Guide

Whether you’re a total audiophile, or you are simply looking to improve the sound quality in your vehicle, a competition-grade amplifier could be an excellent choice for you.

But with so many different types on the market, it can be difficult to know which one is the best for you, that’s why we’ve put together this handy buyer’s guide to guarantee you know exactly what to look for when you make a purchase. 


One very important thing to consider when buying an amplifier is power. Every amplifier you buy will come with a set power outage which is measured in watts, and this determines the amount of power that your car uses to deliver power to subwoofers and speakers. 

When looking at amplifiers, you will notice that two measurements of power are given: RMS power and peak power. RMS power stands for root mean square power, and it means the continuous power which the device will operate at, so out of the two measurements, this one is the most important. 

Whereas peak power is the maximum outage the device will ever hit, and it will only hit this measurement very rarely during peak moments in the audio. If you are looking for an extremely powerful amplifier, you should look for a device that operates at a high RMS power, but the perfect amplifier for you will depend on your situation. 


You should also consider the channels of the amplifier you are considering buying, as this has a huge impact on the device’s functions. Sometimes amplifiers are referred to as different types depending on the number of channels they offer, but there are four main types of amplifiers: mono, 2-channel, 5, and 6-channel and multi-channel amplifiers. 

A mono amplifier produces a low-frequency response with its low pass filters and bass boost. There are several different mono amplifiers on the market, but the best is class D amps as they are a lot more efficient to run as they draw less current and produce less heat while in operation.

Another option is the 2-channel amplifier, these have high pass filters and can operate with either component or full-range speaker systems making them an excellent addition to your car. 

The next option you have is a 5 and 6-channel amplifier which is an excellent choice for power as it works well with speakers in both the front and rear of your vehicle, as well as being compatible with the majority of subwoofers on the market.

 Finally, there is the multi-channel amplifier which is very similar to the 5 and 6-channel amplifier as it is compatible and ideally built for subwoofers as well as working well with full range allowing for a perfect sound. The right type of competition-grade amplifier will depend on your situation and the audio quality you want to achieve.  


It is also important to consider the compatibility of the amplifier with the vehicle you wish to install it in. You should think about the physical size of your car and also the space you have in your car to install one of these devices.

Amplifiers are often installed within your car’s trunk, so you should consider the size of this space and buy an amplifier accordingly to ensure that it will fit. 

Not only should you think about the physical size, but you should also consider the size of your vehicle against the power output of the amplifier. If you only have a small car, an amplifier with a large power output might be too much for the space you have and could be overpowering.

Whereas if you have a large car, you should worry about the amplifier not being powerful enough for space rather than too powerful. 

Another thing you should consider is the compatibility of the device with the music that you are interested in. Depending on the styles of music you play different types of amplifiers will be better or worse suited.

For example, if you listen to particularly loud music you should look for an amplifier with excellent bass subs, whereas if you listen to quieter music inside speakers may be better suited. 

Ease of Use

Finally, you should continue the ease of use of the device. Expensive, more complex amplifiers might seem attractive but the device is no good if you are unable to install and use it. When buying a device you should consider the ease of installation.

Some amplifiers will be easier to install than others and depending on your technical abilities you should buy a device accordingly. If you plan on using the amplifier with other devices, for example, subwoofers, you should also consider the ease of use when connecting these to the amplifier and also the ease of connecting your music.

The importance of ease of use will depend on your technical abilities, but it is something that you should consider before you make a purchase. 

Frequently Asked Questions

What is the purpose of a car amplifier?

An amplifier is an additional device you can add to your car to improve its audio quality. The amplifier works to boost low-level audio signals produced by the head unit so that it is powerful enough to move the speaker’s cone and produce greater sound. 

What hits harder 1-ohm or 4-ohm?

Technically 1-ohm will hit harder than 4-ohm as it will produce a much greater resistance while operating. 

What is the difference between an amplifier and a subwoofer?

Subwoofers and amplifiers are two very different gadgets that can be used to improve your sound quality, but they often get confused with one another.

To tell the difference you can easily look at what the different devices do. Subwoofers simply reproduce very low sounds to improve the bass quality of audio, whereas amplifiers work to amplify the music signal to produce greater sound.
