Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

The radio and display receiver assembly sends a sound signal to the stereo component amplifier assembly via this circuit.

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

If there is an open or short in this circuit, sound cannot be heard from the speakers even if the stereo component amplifier assembly or speakers are not malfunctioning.

Speaker Circuit

DESCRIPTION

for 8 Speakers

If there is a short in a speaker circuit, the radio and display receiver assembly detects it and stops output to the speakers.
Thus sound cannot be heard from the speakers even if there is no malfunction in the radio and display receiver assembly, DCM (telematics transceiver)* or speakers.

for 14 Speakers

If there is a short in a speaker circuit, the stereo component amplifier assembly detects it and stops output to the speakers.
Thus sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly, DCM (telematics transceiver) or speakers.
