So my stock radio will no longer turn on i had an aftermarket sub system in it and the signal wire pulled out and the deck/radio turned off. It wont turn back on. all the wiring is back to stock and none of the fuses are blown. does anybody have any idea what is wrong with my car?

 

Is there a fuse on the back of the head unit it self?

 

no there isn't. i took it to the dealer he said its a 1900 dollar part but warranty will cover it.
