Hi Jason, Might I suggest running some vacuum tubing for the wiring to run through or at least some electrical conduit. It makes pulling the wires much easier, especially if uprgrading later once the walls are covered. I wish I had done it now that I am trying to pull 30 ft of component wiring through to the TV.
