An amplifier is often the most overlooked part of a car audio system but is one of the most important when it comes to determining sound quality. Many people associate amplifier power with volume but this is not correct. Of course, a more powerful amplifier will allow you to achieve more volume from your system before it starts distorting, but more importantly it will significantly improve the sound quality and the amount of music information you hear from your system at normal listening volumes.
