Without cutting the cable apart, I would say the diameter is a good 2 millimeters, which gives it a radius of 1 millimeter. That's an area of roughly 3 millimeters squared. guess what? 12 gauge. So much for all the 16 gauge monster bashing. The component cable itself is probably worth $10 easy. The extra 10 ft subwoofer cable is really nice too.
Thicker is better for longer runs. I use 30-45ft of Canare 4s11 cable shotgun (since there are 4 smaller cables inside which I pair up) and it goes for like $.60-80 a foot. I'm not sure if its in wall rated but it has a ton of jacket on it. P.S. Monster z1 cable is like $3.5 a foot and m1.2 is like $7.5 a foot.ugvT1A. 317 66 100 130 53 19 272 51 185
