Sound Signal Circuit between Navigation Receiver Assembly and Stereo Component Amplifier: Description

The navigation receiver assembly sends a sound signal to the stereo component amplifier assembly via the sound signal circuit.

The sound signal that has been sent is amplified by the stereo component amplifier assembly, and then is 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.
