We are currectly remodeling a house, and I have done what Pbb mentioned. My first thought was to use PVC pipe, but my electrician informed me of a product mfg'd by Carlon - it's a blue flexible corrugated plastic pipe in sizes from 1/2" up to 1 1/4 inch. Locally they call it "Smurf" because of it's color. Lowe's sells it in 10 ft. joints, or you can buy off the spool at your local Electrical supply house. The family room is new construction, so it was relatively easy to install by running under the floor in the crawl space. I had 3 runs for the rear spkrs and sub. The ends terminate at the opening of a "frame", which is plastic and provides a border for the drywall to be cut around. They use these now for running phone and multimedia wiring. I intend to cover the frames with switch plates, which will provide the opening for the cable to pass through. Makes for a very neat installation. Existing construction may pose a few more problems - you will have to have access from either a crawl, basement or attic, and if you're dealing w/ exterior walls, the insulation may make it difficult to feed in the tubing. Would make a good weekend project for the DIY'er, or check with your electrician.
running wire in walls/floor
I am moving to a new house with hardwood floors and I would like it to have my wiring look nicer than what I had going in my current set-up. Who would I contact to run wires through the floor and or walls? I would like it done right and I know if I do it myself I won't be happy with the finished product. I have 2 rear surrounds and 2 rear centers that I will need to run wiring for. FYI: the walls and ceiling are plaster.
