I use three Delco Group 31s from Batteries of Arizona. They're service batteries from the City of Phx that are turned over at least once a year. I paid $20 each for them. Each one tested atleast 875CCA and they're rated at 180 reserve minutes @ 360 amp load. I use one for starting and two for stereo. For the money you can't beat them. I can't seem to kill them in a day of real heavy stereo usage. I also keep an extra two for when we go out of town and don't have power to charge the stereo batteries.
They also carry a true dry cell (AGM) called Dual Pro. These are the best batteries I've ever seen, but a bit pricey for the big ones. The cranking battery is not too expensive. www.dualpro.com
