few things wrong with my 99 expedition
 

battery warninglight comes on, power mirrors won't work, rear wiper dont work, rear amp or subwoofer don't work, and was wondering if anyone could help me? someone cut the subwoofer wire that goes to amp and was wondering if i could just use some wire to hook to the cut wire and run it to the amp and if it matters if i hook it to any prong on the amp? how can i fix any of my problems? thanks
