Running sub cable through wall?

[RobXant]

I want to place my sub a good ways from the rack and the only way to do it without tripping over the cable is to run it in a wall. This doesn't bother me at all, but what wire do you use?
I was at the Orange Box last night and found these keystone type jacks that are RCA on the outside and a mini 110 block on the cavity side. The idea is to use UTP between the jacks. Is this gonna be adequate?

I had to run 2 under the floor. I bought a couple of terminated runs from BJC, and went to it. The hole has to be a bit bigger, but what's the diff? You won't see it anyway. It worked out good for me.
