Speaker Circuit

SPEAKER CIRCUIT

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

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