AMPLIFIER-RADIO
DESCRIPTION
The amplifier is a six channel unit rated at 288 watts.
The amplifier is mounted to the cowl side panel under
the passenger side of the instrument panel.
OPERATION
The amplifier receives fused battery current from a fuse in the Integrated Power Module (IPM) at all times. The
internal circuitry of the amplifier switches the amplifier on based upon a CAN bus message that is received from the
radio receiver whenever the radio is turned on. The amplifier receives the sound signal inputs from the left and right
rear outputs of the radio, then sends the amplified speaker outputs for each of those channels to the speakers.
DIAGNOSIS AND TESTING
AMPLIFIER

Service information.
Refer to the appropriate wiring information.
The amplifier unit should be checked if there is no sound output noted from the speakers. For diagnosis of the
