Once I got all the WireTracks channel installed, I began wiring. I originally intended to use 10AWG cable from bluejeanscable.com, but it turned out to just be too thick to be practical. I ended up buying 250 ft. of 14AWG cable from Home Depot, and using that. I'm doing a full 7.1 system, so I had to wire for side and rear surrounds.

The wiring was no big deal, really. I just routed the wires from the planned speaker positions forward through the WireTracks channel to the planned equipment location. The right side surround had to be routed through our utility room (not shown on the diagram, but it's on the other side of the right wall) and into the under-the-stairs closet, as did the CATV cable. Luckily, the rear speaker location was easy to wire due to the under-the-stairs utility closet that is unfinished on the inside. Four cables (three speaker, and one CATV) leave the under-the-stairs closet on the wall side of the stairs, straight into the WireTracks channel. Very neat indeed.
Along the right side wall, I fished the speaker cable up to a hole on the wall where the left side surround goes and this speaker cable joined the three others and the CATV cable, heading toward the front of the room. Though I think the WireTracks channel could maybe hold a bit more, this seemed to be the maximum practical amount of cable, since the cable clips provided with the WireTracks were a bit tricky to get into place a number of times (they kept wanting to snap back out).

After testing for continuity and identifying which cable was which, I terminated the cable at the front of the room, into an "old work" junction box that was still a little too deep for the very shallow outside wall sheetrock and studs. Thus, it protrudes a bit from the wall. For me, this was not enough to worry about given the amount of work left to do, so I went ahead and completed the installation of the speaker binding posts and CATV jack. It doesn't look bad as is, and will look even better once I fill the gap with caulk or the like.
