[QUOTE="80_Cutlass_mn, post: 356878, member: 545695"] That one wire you were referring to that goes back to the amp is just simply the amps power wire, there is more than likely another wire maybe bigger than this one connected to the battery terminal that goes down to your cars starter. Some, in fact almost all alternator charging wires go down to this wire on the starter. Thats the way my old car was and the way my new car is. All you have to do is look on the back of the alternator and find the post with a wire connected to it and then get a length of at least your amps power wire and put a ring terminal on it, screw it underneath the nut on this post and run this to your battery's positive post. Then you need to upgrade your ground wire from your battery's negative post to your cars chassis. If all you can find is a wire from the neg. battery terminal to the motor block then just simply drill a hole in your car's chassis somewhere close by, sand it down put a bolt and nut through this and then run a new wire from your battery's negative post to this new grounding spot on te chassis using a ring terminal. This is what I had to do. [/QUOTE]
