ZERO.

100%

There's a classic AES paper by Prof R A Greiner, emeritus EE dept at U 
Wis, Madison showing, both with listening tests and math analysis that 
all that matters is BEEF.  That is, low resistance. Woofers are the most 
critical, and  #12 POC (plain ordinary copper) is plenty good for short 
runs. For longer runs, or if you want to get really anal, run #10.

Now what DOES matter a LOT for RFI is that the cable MUST be twisted 
pair. Parallel wire cable (zip cord, glorified or otherwise) is 
notorious for making RFI much worse.
