im sure this dosnt pretain to one car. my integra speakers are cursed lol, right now my fader is all way in front and it sounds fine all the way to wide open. if i begin to turn the fader to rear my and turn volume up my front speakers begin to distort bad and crackle bu as long as fader is all way in front its fine???? also there are no speakers at all hooked up in rear, if i hook speakers up all my speakers automatically distort. iv recheked my wiring on numous occasions and replaced head unit. should i just rewire the rear speaks maybe theres a faulty wire grounding out?? any help is thankful for.

 

check and see if have the wires hooked up with correct color code, blue /green/white /gray. or a wire is grounding out.

 

You may be right, you may have a rear speaker lead that is shorting out, if you fade to a shorted speaker lead, the output stage of the HUs internal amp will distort.

Pull the HU and disconnect the rear speaker leads, see if you still have the problem. 94
