run another 1/0 wire from your front neg battery to the back batteries.... if your serious about spl, you will have to do this.....

if not, find your rear strut bars or drill a hole to get to the cars main chassis....

Actual frame of the car is all I can think of.

how much power do you consider "high Power" There are rules you should follow.

List your amps, how many, what brand and model, How much amperage output is your alternator, How many batteries do you have, how many subs are you pushing, how many speakers....
