Picture 1. You could also run a negative lead from the batt under the hood to the 2nd batt and then run all your grounds on your amps to the batt in the rear...

You would connect all the negatives at the rear batts terminals, not splice them in beforehand...

The last pic provides 0 resitance to all amps. Whereas grounding to the frame will yeild some resistance. I always run a negative cable from the battery. Unibody cars don't really have a full frame so they don't have the best ground.

Of the first two, I would be inclined to use the second method. Having the rear battery and the amps all grounded separately is prime recipe for a ground loop. That said, the last pic is the best, assuming lagre gauge wire.

There's a fuse missing in their diagram.

Yep. There's nothing protecting the pos wire between the rear battery and the amps.
