Hiding wires for plasma TV
I have a question that may sound unusual. I am mounting a plasma tv on a wall in my home. I do not want any of the wires to show so I am going to remove a portion of the drywall and install an outlet on the wall behind the tv. This takes care of the power cord wire but I do not know how I should hide all of the other component wires. I have a DVD, sound system, and a few video game consoles that have to be connected to the tv in some way. My idea is to run a hallow tub in the wall from the floor to halfway up the wall so that I can run component wires such as cable, and AV wires, but not power cords from any of the components. I was going to run white PVC or the black pluming pipe. The reason I was not going to run the gray electrical pipe was because the 90 degree bends are so long and the other two pipes I just mentioned have short 90 degree bends that would fit in the wall better. Would any California electrical codes or building codes restrict this? If anyone has any better ideas on how to do this I would appreciate it. Thank you.
