hey got new 6x9s for my 92 chevy blazer s-10 and discovered i have some faulty wiring. one speaker works, the other doesn't (the old one didn't work either). so it must be the wiring right? so before i tear my car apart looking for the problem i need to know exactly where the wire is routed on its way to the stereo. under the carpet? under the car? under the side panneling? the is my first time doing anything like this and any help would be great thanx!
