Copper wire will run about 0.18 ohms for 100 feet (!) of 12 gauge. If you want 0.1 (what you'll get with your coax if I read the post correctly) 10 gauge copper will do that. If you want even less, try 8 or 6 gauge at 0.07 and 0.05.

If you have a really, really, really, long run, maybe consider an amp with balanced inputs and locate it closer to the action....
