Speaker Circuit: Description

WARNING: This page is about a different car, the 2008 Toyota Avalon. 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 or radio receiver is sent to the speakers from the stereo component amplifier or radio receiver through this circuit.

If there is a short in this circuit, the stereo component amplifier 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 or speakers.

There are two cases when a short is detected.

When a short is detected in the rear No. 2 speaker circuit, sound cannot be heard only from the rear No. 2 speaker.
When a short is detected in any circuit other than the rear No. 2 speaker circuit, sound cannot be heard from all speakers including the rear No. 2 speaker.
