If you must route cord around a corner, you will need to cut out a rectangular piece of

wallboard on either side of the joist at that corner. Use each regular-shaped cutout as the
patch for the wall when you finish. By reaching through the cutout, you can notch the joist to
make room for the cord and use nail plates to cover the cord in each notch (Figure 30).

To patch the wall, reposition the cutout pieces and use joint tape and joint compound to hold
them in place. When they are dry, sand and paint the area to match surrounding surfaces.
It is common to run cord from a speaker location in a wall or ceiling to the attic and through
the wooden top plate that runs horizontally across the top of the vertical studs. You can then
run the cord to the spot above the junction box near the receiver or amplifier. Drill through the
top plate at that point and route the cord through the hole and down into the wall (Figure 31).
