The PO-installed Alpine deck on the car used to work sometimes and not other times. I had a newer BT/ipod Alpine deck that I swapped in for the upgrade and I figured the other deck may have been flakey. Well, it turns out the wiring is flakey. The 'new' deck was giving me errors after starting the car but would work. I figured I had the power and constant 12v crossed over .. but I didn't. I ran a multimeter on the original harness (install is proper, not spliced wiring) and discovered that there was 12v on both pos/neg (white, white/black) wires which go to the front left speaker. I pulled the dash cover to check wiring and it was ok. I disconnected the speaker and there was 12v on those wires. I isolated those wires and re-connected everything and the stereo is 'fixed' .. except that I don't have front left. I plan to install all aftermarket amp and run new speaker wires anyway but I'de like to figure out stray voltage .. or I think it is? Anyone ever have this problem?
