Hey guys ive look around a couple of car forums but I didnt find anything. So I ask you guys. In my 96 cavalier when the rear speaker wires are connected to the adapter from the head unit, and I turn the head unit up 1/4 way the sound starts to distort. This happens with multiple decks, I ran new wiring to the rear speakers, same problem. This happens even when there are no speakers hook up to those lines. But wanna hear the best part? If no wires are connected to rear speaker lines coming off the adapter, any deck plays fine. Goes up to max volume, Im going bald trying to figure this out, please tell me someone has the answer here.

 

Check your tinsil leads first. Look at the back side of the speakers in question at the wire going from the speaker terminal to the cone. Make sure there not damaged or touching any thing. If its not this there my be a short in a wire or possibly a voice coil going out.

 

oops forgot to add it does this with speakers not attached too, and it did this with stock and aftermarket wires running back to the speakers. taking different paths back along the car to get there.

 

agree with theif .your speakers are most definetly messed, up i dont believe it is anything else other then bad contact somewhere. try diff speakers see if that works for ya and voila... problem solved.

 

By pass the harness for your rear speakers or try a different harness. It sound defective.

 

see thats what i thought. maybe a defective harness, but i have them wired on the other side of the harness, connected to the part the comes right out of the deck, before it goes into the harness you have to buy. unless i can somehow get my speaker wire to bypass that harness too. but it would be hard to get 14g wire in there.
