Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
The sound signal that has been amplified by the stereo component amplifier assy is sent to the speaker from the stereo component amplifier assy through this circuit.
If there is a short in this circuit, the stereo component amplifier assy detects it and stops output to the speaker. Thus sound can not be heard from the speaker even if there is no malfunction in the stereo component amplifier assy or speaker.
