With those amps and bad setupI'd run something like a Kinetik 1400 or similar under hood, 3-4 big batts in back and an HO alt. Lots of good batt companies out there, so just compare sizes and pricing from each one(Kinetik, XS, Northstar, Deka, etc). If you could find sum of the big C&D batts that are always floating around for cheap, then I'd suggest going that route to save sum $$.
