Holy crap, that's a lot of wire.

Anyway, if I understand you correctly, you want to run all four runs to a single battery in the back, and then take a single run of 1/0 and jumper the batteries together? Seems like that single run of 1/0 between batteries would be a bottleneck.

Sounds better to run each of the four cables to each of the batteries. i.e. One run from the front battery to battery #1 in the back, run #2 from the front battery to battery#2 in the back, etc. Then from there, you would still have 4 runs to connect to your amps, for even power distribution over all 4 runs.

It would also depend upon how long the runs between batteries would be. Batteries all in a row the runs connecting them would probably be 12" or less, so it might not make much of a diff, but if you have enough 1/0 to do 4 runs I'd wire them as suggest above...

ok let me get my self straight here. after all 8 (power & ground) runs from batt under the hood to batt 1 in back, jump 4 leads of power and ground from batt 1 in back to batt 2 in back then same thing with batt 3 and 4? or am i wrong? if so could someone draw me a diagram.
