posted this else where but, looking for as much in put as possible Well ladies, its time to add some more batteries. I'm plan on going from 1 AT3000.1, to two Current electrical is a 230 amp alt, stinger SPP1200 under the hood, and an HC2000 in the trunk with 4 runs of 0ga Full tilt daily I might see 14v flat as long as I keep it revved lol. Lowest I saw it drop while metering, was 13.5 but I let of the gas... But it seemed to stay at 13.8 or higher after a long burp staying revved. So I have options for batteries mainly, just adding a second to the rear. I'm considering a D3100 since its about the biggest I can get (max cubic inches is 800 per batt in usaci) and is extremely powerful. I was considering a SK-BT140, but it comes out to 1000cubic inches. So two questions, could I get away with just adding a D3100? Or is there a better battery under 800 cubic inches. I'd rather not get rid of the kinetik yet. I do not plan on going full tilt daily as my 12s on the single 3k are pretty loud full tilt also I will be running the amps @1ohm each. Might try to trade for a saz4500, not looking good though.
