Dustin, the room EQ technology is too complicated to be able to just "figure" what you can do. There's no provision to "tweak" the Audyssey EQ settings(although the crossover points can be raised manually); it's either on or off.

Regular electrical wire works fine for carrying electricity to a speaker too. Nothing special can do this any better. Get it in 16ga or heavier, depending on the distance of the run. For more details study this excellent explanation of the facts about speaker wire by a veteran audio professional.

JP(or anybody), if there's difficulty in inserting thick bare wire into a receiver or speaker terminal, there's no reason that the end has to be that same thickness. The resistance of the wire depends on its overall thickness taking the entire length into account, not just the thickness at the connecting end. Strands can be trimmed off the end to, for example, make it 16ga instead of 10ga without appreciably changing the resistance. It might be the equivalent of 10.01ga.
