David, so basically by not having enough battery juice to my amps it can actually cause them to overheat easier? I went to west marine today and one of the employees there suggested blower motor fans due to the large amount of air they can move to help keep things cool. This winter I plan to go to two optima blue tops for the stereo power and prosport 20 to keep them charged but dont have the funds currently. Never really had this problem till this weekend. My harpoon cut off once before but I think we were pounding it pretty hard that day. We were at canyon lake a few weeks ago and I'm not sure how hot it was, probably upper 90s and we jammed in party cove and never had an issue. I know it was like 99-102 this last Sunday and the water we were in was considerably warmer than canyon lakes water. Maybe that can also have an effect
