I was at Home Depot looking for speaker wire and the only stuff they had was wrapped in clear plastic and I didn't think that was in wall rated. I did find some in-wall rated 14/2 "home security" wire. The wire is stranded and since my surround runs will only be 30 - 40 ft tops I figured that 14 gauge would be enough, but I wanted 12. Are any of you familiar with this type of wire? Will it work? Any opinions or suggestions are welcome.
