I think he was referring to a single run of each, I think anyway.

I hardly ever run ground also.

Maybe on 2-3 of the big systems ive done.

Even then it was only like 1-2 1/0's for ground reference

Actually tying to find the grounding system i like.. Ill post once i find it.

..............asked

Well, he ^ "Do I need to run the same size ground lead from my battery to the rear of the vehicle as my power lead? IE - If I run a 1/0 AWG power wire, should I also run a 1/0 AWG ground wire?"

So, no. Think about it. Even having one battery up front and 5 in back, One terminal wont support 5. Maybe multiple grounds from engine block to back would help, but not from battery.

Maybe I understood it wrong :) I thought he meant if a single 1/0AWG power wire is enough on the positive side, is it better to use a chassis ground or a second 1/0AWG power wire on the negative side.

I think you understood it, i'm just using an extreme to prove a point. All I am saying is if you do it, do it from engine ground, not battery.

PPi back in the 90's used to run grounds back to the battery but the rocket scientists always said the cable presented its own resistance over the length.

Then we have the others that want the same gauge, and our all about the chassis ground, however today's vehicles with the spot welds, vehicle frame/unibody dipped in corrosion protection and acid baths... also present its own problems with resistance

You also have to look at how the battery is grounded also (and alternator supply wire)

I personally like the same gauge, and grounding to the frame when I cant ground to the battery :) either way the amp turns on and produces music... hell some are even going strong for over 15 years now in the same car :)
