If a boat is anything like a car, the amp's negative post should not be connected to the battery, but to the ground of the boat. In a car, the entire chassis is grounded to the negative terminal, so when you run a line from the positive terminal of the battery to the positive post on the amp, and a line from the negative post on the amp to the chassis it is a complete circuit. I highly recommend placing a fuse on the positive line from the battery to the amp. Wiring this way prevents the amp from blowing up your battery, as well as prevents the battery from blowing your amp. Hope it works.
