Kicker 750.1 Amp wont play music

This is a really powerful amp. You may have blown your sub if it's not a very powerful sub. Check all the wiring. Could be a bad ground. Or bad power connection.

The wire you are needing to check is the Blue antenna wire that runs from the back of your deck to the amp. More than likely if you are getting a green light on the amp than that means this wire blew a fuse somewhere or blew the amp itself. I would say re-check all the fuses. (there should be one in front of battery wire and some on the amp) If these are still good and you are still getting green light but no sub than check the wiring for the box. I just had to re-wire my box because one of the cables came loose in the box. I have a Kicker 750.1 and a kicker 12" L7 so i understand what you mean... it just takes time and understanding. If everything fails and still it wont work.. than hook the amp up to a friends car and see the results.

It is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs
