Yeah normally I'm very good at hooking up stereos but this one stereo is the only one that's had me stumped. I know about the 9 volt battery I do recone speakers I've use that when I couldn't tell which wire was positive and which one was negative on the coils. 1 thing that is weird I took the door panels off to check the color of the speaker wires they are all the same color but when they go into the amp they're different color so I'm assuming that they brake connection underneath the carpet somewhere. As soon as I get off work today I'm going to try your diagram out and I will leave you a message let you know what I find out thanks again.
