I have just put a new head unit in my 2001 cavalier and i still am using the stock speakers. Everything works fine but i can't turn off the back speakers when i fade it to the front. I noticed that there are 4 wires in each of the 6x9's in the rear, 2 wires are the wires i connected to the head unit. But does anyone know where the other 2 come from? On both speakers they are blue and green and seem to lead under the back seat. Ive never seen 6x9's with 4 wires.
Normaly speakers have thease wires i dont know y it is not fading the other wires that ur talkin about are the grounds make sure that all ur conections are good...if that dont work then try another head unit...if thats not the problem go to your local audio store...
