you should tell us how long of a wire run you are planning. if you are going less than 10 ft 14 gauge would be fine. if your going father than 10 ft i would recommend 12 gauge. if you haven't bought wire yet i would tell you to get 12 gauge.. i have 10 gauge wire going to my L/R/C and 12 Gauge going to my surrounds. larger wire is almost always better.......
