u need to get a line output converter from somewhere, at best buy they are like 25 bucks. This will giv u rca preouts to get signal to the amp. With teh LOC, you will need to tap into your left and right rear speakers usually. You will also then need a remote wire from an accessory circuit in the car. Remember to fuse it if u get it at the ginition harness jsut to be safe with a 3 to 5 amp fuse. Good luck.
