Question about Sony Xplod XM-554ZR Car Audio Amplifier
REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT POWERS UP FINE,THEN PROCEED TO CONNECT THE SPEAKERS FIRST AND SEE IF IT STILL POWERS UP FINE, THEN MOVE ON TO RECONNECT THE RCA INPUTS. AT THIS POINT YOU SHOULD HEAR MUSIC, IF NOT AND THE AMPLIFIER IS POWERED UP AND NOT GOING INTO PROTECTION, THEN YOU MAY HAVE AN INPUT PROBLEM FROM THE RADIO. IF THE AMPLIFIER FAILS TO POWER UP AT ALL AND YOU HAVE VERIFIED THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN THE AMPLIFIER WILL NEED TO BE SERVICED. YOU CAN CHECK THE VOLTAGE TO THE REMOTE TERMINAL TO MAKE SURE THAT IT ABOVE 11 VOLTS, AS SOMETIMES A FAULTY REMOTE OUTPUT FROM THE RADIO CAN SOMETIME FAIL TO TURN AN AMPLIFIER ON. REMEMBER IN ANY CASE YOU ONLY HAVE AN AMPLIFIER, AN INPUT AND A SPEAKER. USE THIS PROCESS TO HELP YOU DETERMINE WHERE THE PROBLEM IS LOCATED. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
