a direct run of the ground wire is what you want. Yes. Steel is a horrible conductor. Copper is much better. Unless you are using aluminum wire which is still better than steel but worse than copper.

Alright so if i run one from pos and one from neg to the rear battery where should i ground the amp? Straight to battery.

If you have a trunk battery. Yes just ground it to that.

Ok. Ive always tbought shorter the ground the better. And also thought it was bad to ground amps straight to battery.

My amp in my signature is grounded to my batteries. and I run dedicated grounds.

Shorter the wire in general is better. The shorter the wire the more power it can handle. But you can't make it short when you are running the length of the car.

And when you ground your front battery to the frame/engine. And then ground your trunk battery to the frame. You are using your cars steel frame to send the current threw. That makes for a really garbage ground.

You should notice A BIG difference in voltage drop. There should be very little voltage drop when you run dedicated grounds and have proper electrical.
