THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE RADIO OR AMPLIFIER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL POWERS UP ON ITS OWN, THEN REMOVE THE REMOTE TERMINAL COMING FROM THE RADIO. IF THE AMPLIFIER SHUTS OFF, THEN YOU MAY HAVE A SHORTED TURN-ON TRANSISTOR WITHIN THE RADIO AND IT IS OUTPUTTING THE DC NEEDED TO TURN THE AMPLIFIER ON. IF YOU REMOVE THE REMOTE TURN-ON FROM THE RADIO TO THE AMPLIFIER AND THE AMPLIFIER STAYS ON, THEN THIS POINTS TO A FAULT WITHIN THE AMPLIFIER AND IT WILL NEED TO BE SERVICED. MAKES SURE THAT THE AMPLIFIER AND RADIO GROUNDS ARE 100%. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
