i have three of the biggest ac delco deep cycles that you can get in my boat. one main and two aux. when ont he water we can listen to it for about four or five hours straight on the two aux. at crazy volumes with 2200 watts and still start the boat on the same two, not the one in reserve. that system is probably one of the more demanding ones out of the ones on this site, simply because it runs off of pure battery power, not off the alt when the motor is running, and they get charged every time in.
