Building a Low Power DiY marine bluetooth speaker set

[BiGyElLoWhAt]

My dad has been asking about some speakers for his boat, something that will move a bit of air, not too big though. I'm thinking 1x12. He also wants it bluetooth and powered externally, so it doesn't drain the boat battery.

So I'm thinking 1x12 speaker in a small box that can fit inside the compartments in the boat, psoc hookup for bluetooth, and then the real question is power. Spacially I think a car battery is just too big, powerwise I think something like an RC battery is too small.

Thinking of this as a DIY project, what suggestions/advice/improvements do you guys have?

Why DIY instead of an existing commercial solution? What kind of wattage and battery life are you looking for? I'm seeing 12" bluetooth speakers on Amazon (with batteries) starting at $90.
