Gents, what battery should i look into purchasing for my '03 mustang GT convertible? I'm going to be installing a full stereo system in (including a NINe.1 and NINe.2 with 2 13Ov.2's). I don't want to go overkill but don't want to run dry either. I'm not up to date on all the latest battery technology and have heard mixed reviews on Optima. Lead me masters.

deep cycles are great for show cars or cars that only get started from time to time but otherwise you will be fine just getting the largets CCA rating you can find.

What's a CCA rating?

cold cranking amps

Optima FTW

again, the optima or deep cycle batteryies are great for cars that do not get started all that often but will not buy you much more then that.
