800 Watt Amps Buyer’s Guide

Power Ratings

Car speakers need matching amps to boost power and improve sound quality. If the amp isn’t compatible with the speaker, it will affect the amp and damage the speaker’s driver. To avoid these issues, our team recommends that you look for the power rating (RMS) on the speaker and then find an amp that can offer between 75% – 150% of the rating.


The number of speakers will determine the number of channels you need. If there are two speakers available, a 2-channel amp can power them efficiently. You can also bridge the two channels to power a subwoofer. 

Type of Amplifier

There are four types that you can choose – Class A, B, AB, and D. Class A is more powerful than the rest because it reproduces high-frequency sounds. B consumes less heat than A when reproducing high-frequency sounds, and D consumes the least but is mainly designed for subs [1].
