yea because like i said I can only fit an 8inch depth because my box is 13 cubic ft so those small battries will be good and im runnng them under an amp rack, one question though i dont need bus bars correct can i just run 0 gauge from each one, and how should i ground them undernieth my rear seats like 4ft grounds where my grounds are for my amps because I dont no of any good ground area's in the rear
