Fix Up Jon Boat How Do You Hook Up A Marine Stereo?

How do you hook up a marine stereo? - fix up jon boat

I have a 16-foot Jon boat, I really want this winter and had hoped to put a stereo into the sea at the same time. I need to know just how difficult it is to get in touch. I have a 12-volt battery, but my engine is independent, so I can just run the stereo from the battery and load each time, or I do?
