Question about Infinity 7540A Car Audio Amplifier
It was hitting a loud note and just cut out. i noticed that the power light blinked off and on and my speakers were moving in and out very slowly in opposite directions. i have a protect light and clip light and power light, and just the power comes on for a second, every five seconds and a bit of sound comes out. help please
Take the input leads out of the amplifier for a start, but leave the power and remote cables connected.
See if it still turns on and off. If still faulty, you have probably blown a power transistor inside and the amp is shutting down when the output rises each time. It will almost certainly need looking at. Also make sure you are running into the correct impedance load. If you have hooked up too many speakers you will cause damage.
