What wires do I hook to the 12v marine battery to hook up an auto radio?
memory wire is usualy for the clock and keep the stations set, a marine battery works just like an auto battery, plus side is possative, and minus side is ground, should hook red to possative side of fuse block and black to ground side, yellow should have constant current at all times, but if your like me and dont get to use your boat as much this will pull the current from your batteries, and remember always go through a fuse block to reduce the risk of fire or burning out your radio, hope this helps
