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 "6 Speaker 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 "9 Speaker System".

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.
