That's system is gonna thump. I agree with the above regarding a 3 or 4 bank system. If you plan on party coving it or swimming with it that system is going to suck your single battery dead quick. I say single because you are going to want to make sure you have a safety/ starter battery so you can fire up after draining your stereo battery.
That is boat is gonna rock tho.
