Big 3 first definately. I'd definately upgrade the front batt and grab an alt if you have the dough.
My truck with a kicker 550.2, and a sundown 1500 @1ohm would make my dash lights dim full tilt (headlights and A/C on) and I have a yellow top up front, big 3, and a 200amp alt. My voltage dropped down to low 13's.
