No. In theory, the resistance would go down, so the amperage would go up.

A smaller cable, with the same length, would result in higher resistance, and thus, less amperage.

Ernie, here is a handy-dandy little resistance and voltage drop calculator http://www.stealth316.com/2-wire-resistance.htm I think most of our battery cables are 4 gauge, right? If you add in the additional few feet of wire that it takes to move a cable to the back (my current battery-to-solenoid is 32 inches long) it will calculate the additional resistance and voltage drop. It even has a "battery move to trunk" example.
