4 Channel Amplifier

A 4 channel amplifier is an audio amplifier that has four separate channels or inputs and is designed to power multiple speakers in a car or home audio system. It is typically used in car audio systems to power four separate speakers or a combination of speakers and subwoofers. In a home audio system, a 4 channel amplifier can be used to power two pairs of speakers in different rooms or zones, or to power a combination of speakers and a subwoofer. A 4 channel amplifier can range in power output from a few watts per channel to several hundred watts per channel, depending on the specific model and application.
