im goin 2 try and get 2 runs done
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 $$
i was thinking about hitin up 99vic (i think that his name) about some of tho batterys he salein and idk about fitin 4 batterys in the back
I can tell you for the car you can fit a D3100 under the hood if you take out the battery box and modify it to fit. Also you will be able to fit 2 D3100's in the spare tire well with no issues, but I'm sure that's where your tank is going to go so good luck getting everything to fit. Especially trying to run 6 amps in that car and finding a place to put all of them. I'm running 3 amps in mine right now and no room, but I have to try an squeeze another in there somehow to power my kicks. It could be cause I have 2 15's and a huge box for them, but with 4 sub amps what are you planning on running sub wise?
im goin 2 do wut steve did and put the amps under the box and i did not know a d31 would fix thanks bro i have something 2 work on now =) ya the tank will be in the spare tire place and in goin 2 have two big bang squared 12"
