Thinking of buying the dual skar evl 12 box and subs. I have stock electrical 160 amp alternator but im gonna b doing the big 3 upgrade with 0 gauge. The package comes with the rp2000.1 amp but im problably gonna buy everything seperate underpower them and go with the rp1500 watt amp since i only have stock alt. Will i still need an agm battery? If so any reccomendations on the brand and size. Im doing this just for now until i can afford a 320 amp alt and the skv3500 amp.
