Im looking for an easy way to test and amp. i have it all hooked up ion the car, and i know thw poer works and everything is setup correctly, but i might have torn the remote wire. is there anyway to make antoher remote wrie just to test to see if the amp even works before i start tearing the car apart? Can i get like a 12v battery and hook a wire to it and send a change to the remote? any suggestions woudl be great

Thanks.
