It is a 110 Qt cooler, speakers side is capped off by two plastic cutting boards epoxied in for water protection when the ice melts. Radio runs off of a Lawn and Garden type battery with no Amplifier. The battery last FOREVER it seems like off of one charge. I play softball tournaments every weekend and this charge probably has 30+ hours so far without a recharge. It is hooked up to a toggle for power shut down since there isnt really good way to make an ignition/remote turn on wire. I have built about 30 or so of these thing, but this is the first one i've done for myself. I have right around $350 invested in this one.
Thanks bud, i really enjoy the thing!
