If your amp is turning on just fine, then you'll want to make sure that it's receiving an input from your head unit. This is a pretty easy process if you have access to both the head unit and the amp - simply unplug the RCA cables from each unit and reconnect them with a good set.

Verify that the head unit is turned on, the volume is turned up, and cycle through multiple inputs, like the radio tuner, CD player, or auxiliary input. If everything works after bypassing the installed RCA cables, then you'll just need to replace them with a good set. If you get sound from one input but not another, the problem is in your head unit, and not your amp.

If you still don't get any output from your amplifier, then you'll want to try disconnecting it from the speakers in your vehicle and hooking up a known good speaker that isn't in your car. If the amp drives that just fine, then you have a problem with your speakers or wiring. If you still don't get any sound, then you could have a faulty amplifier, although you'll want to check that it isn't in "slave" mode and that you don't have conflicting filters before you condemn the unit.


Thanks
