I know you are trying to assist the OP but I would not touch that RCA stuff if it was free. The RCA wire, as well as GE Pro, is CCA, Copper Clad Aluminum, and far less conductive than pure copper.
SS07, just use 14 gauge Monoprice that has been continuously recommeded to you. It is pure copper and outstanding wire for the money. In other words, while not the cheapest it is the best VALUE. At just $25 for 100' spool, why short change your system???
