AMP Sound Signal Circuit

DESCRIPTION

The radio receiver assembly sends sound signals to the stereo component amplifier assembly through this circuit. Sound signals that have been sent are amplified by the stereo component amplifier assembly, and then sent to the speakers.
If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.
