3-Channel Amplifiers Information

3-Channel Amplifiers

A car audio amplifier acts as the power source to your sound system. Technically, the amplifier modulates power generated from the car battery. An amp specified to your speaker's inputs will fully orchestrate your sound system with low bass beats and high frequency sounds.

3 channel amplifiers are great combo amps, because they allow users to power a pair of speakers and a great subwoofer amplifier for smaller sized vehicles were you tend to not really have the need to deal with rear speakers. These three channel amplifiers also provide a more inexpensive option towards upgrading any car audio system.

A 3 channel amp is constructed as a two channel AB amp up front, and has a third channel on the rear channel like a Class D amplifier. The main difference with a 3 channel amplifier is the application of two speakers and one subwoofer.
