Does a run of ground wire from front to rear necessary??

[RnK1026]

im having voltage drops more then i should. 200 amp alt, 2 2400s in the rear and 0 gauge all around and still drops to much. i am running an old school US2000X, so it does pull some current, but not like this. is runnin a 0 gauge ground from front bat to rear bat gonna do a dramatic difference? thanks all-----Rob

Well the facts say wont make much of a different. But never know might just have bad grounds on frame and a ground run will help alot... might not...

What "facts?" Where are the batteries grounded out back? If they're not grounded to the frame, I'd give that a go first. A unibody isn't a great conductor, but the frame should be at least as good as a single run of 1/0.
