I have a 2K3 GAGT, 3.4L V6 and I want to add some aftermartket stuff and would like some advice regarding a battery/alternator upgrade. Currently, I have a 105amp alt and an AC Delco Pro, 75-6YR ( 650 CCA and 320 Load Test Amps). I am planning on doing a "Big 3" upgrade first. Eventually, I plan on installing 3 electric guages (AutoMeter) and a new audio system. The amps alone will be sucking back about 620 watts RMS. At the moment, I notice the headlights dim a bit when I turn my rear-defroster on, so I imagine I'll need to upgrade some stuff in order to avoid unnecessary breakdowns. I'd be interested in model numbers or specific places or websites that sell upgrades for GA's, specifically, battery's and alts.

only 600 and something watts
i'd say your good with what you got
but upgrading the big 3 wouldn't hurt!
maybe a yellow top batt. too
