does anybody know what the wiring pinout for the rear door amp is?

mine is dead (it seems to have voltage to it but my speakers have no sound :(). ive been trying to find a stock one but i cant so id like to know the pinout so ican rewire it to an aftermarket amp or something. thanks.

Somebody has got to know something about this, im having a hell of time trying to find one. somebody here must have dealt with this thing before right?
