I have 2 speakers that are about 6 inches in diameter each. This is a pretty ridiculous question but how do I wire them to play music on my boat? I have a large battery that could power them and an ipod that I could get the music from but can anyone tell what else I need to buy for this to all work. As you can tell, I know next to nothing about this kind of electronics so please try to word everything in a way that I would understand. Thanks everyone.
