An ACDelco GM Original Equipment Audio Amplifier is part of the audio system,
and is a GM-recommended replacement for your vehicle’s original component. The
purpose of the amplifier is to increase the power of a voltage or current
signal. The output signal of an audio amplifier may consist of the same
frequencies as the input signal or it may consist of only a portion of the
frequencies, as in the case of a subwoofer or midrange speaker. The audio
amplifier amplifies the signal and sends it to the appropriate speakers. Each
of the audio output channel circuits (+ and ?) at the audio amplifier have a
DC bias voltage that is approximately one half of the battery voltage. The
audio being played on the system is produced by a varying AC voltage that is
centered around the DC bias voltage on the same circuit. The AC voltage is
what causes the speaker cone to move and produce sound. Both the DC bias
voltage and the AC voltage signals are needed for the audio system to properly
produce sound. These original equipment audio amplifiers have been
manufactured to fit your GM vehicle, providing the same performance,
durability, and service life you expect from General Motors.
