I have a 09 Saturn Aura XR (l4) and am wanting to take use of the other 2 channels on my amp. I have already amlified the rear deck speakers however i really dont want to have to take the door panels off to run new wire. So my question is where would you splice into factory wiring at? I googled a wiring diagram and it said that the front left speaker wires are gray and tan. So I took the trim off on driver side of vehicle and saw a gray wire, I cut this gray wire hoping that it would make the door speaker stop playing however it was not the correct wire. I really dont want to take the dash out again or take door panels off as that is a pain in the ass. any suggestions?
