Well i dont know whats wrong with it and it seems to be made to not be able to take apart to inspect. It turns on fine and all no protection light but no output. any ideas???

 

Maybe the input is the problem...?

What I mean to say is to ensure that your source signal is being sent properly. Maybe something disconnected from your head unit?

It'll really help out a lot of you go into detail about how the amp is being used, how its connected, and so forth. The problem may not be the amplifier at all.
