How does a car amplifier work?

If you’ve invested in a new set of speakers and a brand-new head unit, you will have already noticed the superior sound quality. But, if you want to fully optimise your stereo system, then you need to invest in a new amplifier. To help you understand the role of an amplifier, here is some information from the team at GC Car Audio.

What do car amplifiers do?

An amplifier is a device that amplifies a weak audio signal in order to drive the speakers. This amplification process is an essential part of every car audio system, with the quality and power of your amplifier dictating the sound quality and volume of the sound. The more powerful the amplifier, the cleaner the sound from your speakers.
All car audio systems are equipped with at least one amplifier, even if it is a basic amp that is in-built into your head unit. Many car audio systems include a secondary audio amplifier to drive a subwoofer.

What should you look for in a car amp?

When you are shopping for an amplifier, you need to ensure that you purchase the right one to suit your speakers. There are two main power ratings for amplifiers: root mean square (RMS) power, and peak power. RMS is the continuous power produced by the amplifier and is measured in watts. Peak power is also measured by watts but refers to the power available for brief sound increases and is always greater than the RMS value.
Before you commit to buying an amplifier, you should ensure that the RMS value matches that of your speakers. This will ensure the sound quality is not over or underpowered. Overpowered speakers are at risk of overheating or internal damage.
