[QUOTE="Walled_Taurus, post: 5922485, member: 609240"] Positive from front battery to the back battery positive. Then from that positive to the positives of any more batts you have back there. Then connect all the negatives to each other from the back batts then ground it to chassis if possible if not then body just make sure its zeroed. If you have the cable dont ground the back batteries in the back run 2 leads of 1/0 from the grounds on the back batteries to the front battery negative then ground off of just the front battery. If you connect your amp grounds to the negative grounds on the back battery or batteries then run 3 leads of ground from back batt to front batt. [/QUOTE]
