See this is why I ask these questions.... to get honest opinions which is awesome thanks! What do you all think average runtime of a 250w amp and hu would last off a plain interstate battery single deep cell? before I could go hours with it turn to a soft rocking decibel, I just don't want to get stuck out on the sand bar after laying around for a few hours relaxing and do the humiliating call for a tow by the pontoon!!!! The more I think about batteries in the rear lockers the mroe i think it would be better hidden under seats somewhere. I do like the idea of up in the bow since that is sort of wasted space on the one side.
