run 1/0 or 2 1/0 lines from the front batt positive then bring it to the positive of all the other batteries. (parallel) you can make buss bars or whatever you want to connect the batteries in the back to save wire and $$$... then ground out the batteries in the back............... (at least this is what i know how to do. hehe)

like normal you are going to want to fuse the power cable going from the front to the back. then the wires coming off of the rear batts don't HAVE to be fused, but you are better off running them to a fused distro block just for safety's sake...

ok now the grounding of the amps can i take the negative of one of the extra batteries and hook that up to the ground on the amp? or should i just ground the amp at the same spot as i do the batteries?

Put a fuse in the main line (from front to back) near the extra batteries too. If something should happen to your line, the front fuse will blow and *still* arc from the rear batteries if there's no fuse to blow back there.

You might also want to think about installing a battery isolator on the rear batteries so that they do not draw current from the front battery yet they recieve the charge from the alternator.
Basically this is a large diode setup to keep the front battery from draining due to the current draw from the amps.
