Car Radio and CD Player When the volume is increased to maximum limits the sound can break up harshly, this is known as distortion. The amplifier distortion level is the most important specification of a sound system, the lower it is, the better the sound quality. The best level of distortion is less than 1 percent at 3/4 volume. Amplifiers drive power to the speakers and are an important part of the speaker system. An amplifier receives a low amperage signal from the stereo head unit, then it converts that signal to high amperage to drive the speakers. External amplifiers can demanded more power from your vehicles electrical system and special considerations must be made if too much amperage is being drawn from the system.

Sound can be divided into separate frequencies which are then sent to each independent speaker depending on its designed range. The woofer creates a deep bass extension to provide lows without perceptible distortions, while the mids are designed to handle the mid-range sounds; lastly the tweeters handle the high frequencies.
