Question about Infinity Reference 7541a Car Audio Amplifier
Infinity Amp 7541a, amp was working fine, Took it out of one car to put into another, Hooked it up right but protect light comes on for 5 sec. then goes off and that all it does?
REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL GOES INTO PROTECTION 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. KEEP IN MIND, THAT DURING THE INITIAL TURN ON OF THE AMPLIFIER, THEY SOMETIMES WILL ILLUMINATE THE PROTECTION LIGHT WHILE STABILIZING THE POWER SUPPLY AND OUTPUTS, BUT AFTER THAT THEY SHOULD SHOW NORMAL POWER UP. IF YOU GET IT TO POWER UP FINE, THEN RECONNECT THE SPEAKERS AND IF STILL OK, THE RECONNECT THE RCA'S. IF IT IS STILL POWERED UP, THEN START TO TURN UP THE MUSIC. IF IT IS STILL POWERED UP AND NO MUSIC, THEN CHECK THAT YOU DEFINITELY HAVE A PROPER SIGNAL COMING FROM THE RADIO. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
