Im currrently planning an uprade from my 500 w rms rockford p1 enclosure to something like 2 sundown SA- 12's or similar. in a 2003 gmc envoy
the sa's would be 1500 rms together and figuring in 125 w rms x 4 for components i would be at 2000w rms. (2500 w draw accounting for efficency, d class amps)
my question is.... do i need an alternator?? orr no? stock alt on gmc envoy is 150 amps
and i was ether gonna go with 1 xs power agm d3400
or 1 Duracell Ultra Platinum AGM Battery with Dual Terminals for BCI Group 34/78 SLI to replace stock battery,and Duracell Ultra BCI Group 27M Deep Cycle Marine & RV Battery as a secondary. what do you guys think? im kinda lost here. have no idea where to go
amperage draw for 2500w from battery is 180A.
