Right now my setup is(see sig) and I have BAD voltage problems. I believe my problem is that I have a 2ga wire from the front battery to the back(came with the car,to lazy to change it) where I branched 3 runs of 4ga wire off it to my 3 amps. Now I was wondering if I ran 1 or 2 runs of 1/0ga from the front to the back would that cure my problem?
