The voltage is the same, but there is a major difference with respect to "ground".

On an automobile it is only necessary to run the power wire to the amp/stereo. The ground wire is usually connected to a nearby spot on the frame. On a boat, there is (usually) no metal frame so a ground wire has to be run back to some central ground point. For the stereo deck, there is usually a ground "bus bar" up under the dash that can be used. For the amps you will need to run a large wire back to a common connection point, which is usually on the engine.
