Hey guys im new to this forum. My name is scott from OH. I registered on this forum because you guys will have more knowledge on these cars. I have a brand new 08 G6 sedan. Well me and my buddy ghetto rigged a system just so i can see wut it sounds like. Well I really don't know how to hook up one up so he basically did all of it. It worked but the amp won't shutoff when the radio did (he plugged a wire to the radio fuse on the passenger side of the car). Well I guess he cut the wire that was connected to the radio fuse so all I had to do to turn the amp off was untwist it lol. Well I kinda pulled hard on it and heard some sparks. Now the car won't start. It won't even crank. No power whatsoever in the car. I checked the fuses and they seem good. I can't figure out what other problems there are?
