When you are looking to install an upgraded sound system in your car, if you want it to bang, you’re going to need to put in an amp. While their different options exist, an amp with five channels gives the most flexibility and versatility. There are numerous 5 channel amplifier types on the market.


Buying guide

 

While this is often a positive thing, it can be perplexing, especially if you are unfamiliar with amplifiers. Recognizing this, we've compiled a list of things to consider when evaluating the best 5 channel amplifier purchase.

Class Amps

Class Amps are divided into groups based on how their sound output is powered and dissipated. Each class has its own set of qualities and benefits and drawbacks.

Class A - excellent sound quality, but quickly overheats and is inefficient.

Class B - conserves energy by "going off" at certain points during the sound cycle, however, there is some distortion.

Class AB — A combination of classes A and B that allows the amplifier to stay on when there is no signal but at reduced power, allowing it to overheat less easily while maintaining Class A sound quality.

The signal is regulated by Class D output transistors, which turn on and off quickly. Although there is some distortion, it is outside of our hearing range, thus it can be a decent alternative to Class A or A/B.

Class A/D — Employs the same input signal as Class A but uses the Class D energy-saving output mechanism.

Class BD is particularly efficient since it employs a Class D design while maintaining the same high level of sound quality as Class B.

Class FD — This amp has all of the advantages of Class D amps, but it filters out the signal switching distortion.

RMS

Power is a measure of how powerful something is. The total amount of continuous power produced by an amplifier is represented by RMS (Root mean square), which is commonly measured in Watts. Most 5-channel amps have an RMS power range of 600-1000 watts. Even yet, there are a few types that can handle greater RMS than the above-mentioned range. Whatever the case may be, more RMS output always equates to more power. To put it another way, the higher the RMS, the better the result.

Impedance

Essentially, this is a measurement of electrical resistance. The impedance measurement of 5 channel amps is either 2 or 4 Ohms. However, depending on the nature of your sub, you might need to go a little higher, to around 8 Ohms. For smoother functioning, you should make sure the amp's impedance matches that of your system.

Peak Power

It's the greatest amount of power an amplifier can handle in a short amount of time before it burns out. This metric may not be as essential as the RMS. Nonetheless, peak power can make or break an amp.

There are several 5-channel amplifiers on the market, but not all of them can provide you with the level of customization and sound quality that you require. Use them as a guide to choose which option is best for you. We hope we were able to assist you to limit down your options to a few viable options. Hopefully, you'll be able to locate something that meets both your needs and your budget.
