In hooking up my rear surrounds, I found that there is no clean way to run speaker wire to them because of the design of the room, placement of doors, a fireplace, etc. In-wall is also not an option. I am looking into the possibility of simply running the wire "as the crow flies" under the carpet, and am looking for somthing to protect the wire. The wire is flat, and some kind of plasic conduit (also more-or-less flat) would be ideal. I am using 14AWG wire, and the run(s) would be about 15'. Obviously, I don't want a bulge in the carpet, but at the same time I want the wire to be protected against foot traffic. Does anybody have any suggestions?
