I am having a room renovated and want to have it pre-wired for surround sound. I'm not sure what type of in-wall cable would need to be run. The room is 18x15 and I will plan on buying 2 50-60 ft spools to make sure I have enough. But I'm not sure what should buy. Looking at Home Depot and Lowes all I saw was 16-18 gauge wiring for in-wall. I see the Monster 14-gauge wiring. http://www.crutchfield.com/S-JXzwm8c...2&I=119CS14260 Will 14-gauge be enough or do I need 12-gauge for longer runs? I've seen some at Parts Express don't know the quality of it. http://www.partsexpress.com/pe/showd...number=100-740 I need to have this by Tuesday so any feedback would be greatly appreciated.
