Power Amplifier

When the radio is turned on, CKT 314 (PNK) supplies voltage to the Power Amp Relay coil feed. CKT 150 (BLK) then grounds the Power Amp Relay coil to complete the CKT. When the Power Amplifier Relay is energized, voltage supplied to the Power Amplifier Relay from CIG LIR Fuse 13 supplies voltage through CKT 640 (ORN) to activate the Power Amplifier. The Power Amplifier grounds through CKT 150 (BLK) 10 Ground G202. The Power Amplifier receives input signals from the Left Rear and Right Rear speaker channels. The Amplifier then sends these signals as outputs as follows:
