Speaker Circuit

Speaker Circuit

DESCRIPTION
- When the vehicle has a built-in type amplifier, a sound signal is sent from the radio receiver to the speakers via the "standard system" circuit.
- When the vehicle has a separate type amplifier, a sound signal from the radio receiver is amplified by the stereo component amplifier and then transmitted to the speaker via the "JBL system".

If there is a short in this circuit, the stereo component amplifier detects it and stops output to the speakers.

Thus, sound can not be heard from the speaker even if there is no malfunction in the stereo component amplifier or speaker.
JBL Type:

When a short in the speaker circuit is detected, all sound output is stopped.
