i have a 01 grandprix gt....dont have onstar and dont think i have bose or monsoon system. my problem is when i bought the car the rear deck speakers worked for about 2 days(when it was warm out) after it got cooler out they quit working. then they would work again when it was warm out again..i chalked it up to being blown speakers or possibly something with the wiring going to the speakers. i bought a alpine-plt5 inline sub box w/amp from a buddy(works awesome) and bought a pioneer hu and got the scoche wiring kit for both got it installed and worked great for about a year til the other day on the way to work, rear deck speakers were working everything was good then all speakers except subs quit! and have not came back on yet. i looked in the trunk and behind the glove box and behind hu to find an aftermarket amp and cant find it i know there should be one cuz i have a fuse for it in the fuse block and all my fuses are good. am i gonna have to run new wires from the hu or can i bypass somewhere?
any suggestions or ideas would be greatly appreciated goin nuts without sound
