on a 2002 Dodge Ram installing 1 Kicker ZX-750.1 and 1 kicker zx-350.1 Do you need an extra battery or will the stock battery keep up? This is powering 2-CVR-10's and 2 each ks-65 and ks-69 Thanks

stock battery will do fine but throw in an optima yellow.

don't worry about upgrading the battery unless you plan on running the stereo with the motor off for extended periods of time. The stock alt on that truck I think is 160 amp....your fine with just two amps.

yeah i've got about 2 amps in my 03 ram...a solid audio 1800 2ch and memphis 1500 4, stock battery does fine still
