My brother is setting up a HT using thick stranded 12ga wire, not your normal speaker type of fine strand...sounds fine except he gets no signal to the sub woofer. He soldered the ends with rca jacks....could this type of wire prevent a signal from the receiver on the SW output? when hooking it up straight to the receiver with a coax it works fine.

thanks for the help.
Brett
