rcaudio, I bought some of the flat monster cable for an under carpet run in my bedroom. It was much thicker than I expected after it was installed. I put it under the carpet and pad and then re-ran it between the two. I could still feel it if I walked over the spot where it was (which was right by the door. . . ). Maybe a better quality pad/carpet would eliminate the problem. I decided to bite the bullet and run in-wall wiring and get rid of the flat cable all together. For me, it was definitely the way to go.

If you are in a house where you can run in wall wire, I would suggest it from my own personal preference. Unless the area where you run the flat cable will be seldom if ever trod upon, in which case it would probably work wonders and be the easiest.

Just trying to help out and save a few bucks (and hours) if your situation was anything like mine.
