[. . . ] If you plan to pull many rooms at the same time through a central route, walk off the distance to each destination, add a generous fudge factor for turns and other obstacles, then cut off each section so that you have a bundle of wires you can pull at once. Whenever you run the wire further than four and one half feet from a hole in a stud or joist (open attic space, going up walls, etc. ), fasten the wire to the joists or studs using cable clamps or appropriately sized wire staples. The wire should not have large sags in it, nor should it be too tight. Try to protect the wire from being stepped on in attics or other unfinished crawl spaces. There are guard strips, raceways and conduits which can be used to protect the cable. Consult the local building code for special requirements in your area. Concealing Speaker Wire in Existing Walls This is actually a fairly simple task if you restrict your choice of speaker locations and wire routes to the interior walls or ceilings of your home. Interior walls in almost all North American residences are hollow, so that it is easy to flush mount speakers into them and route new speaker cable around the house. What you see when you look at the painted wall board, plaster, or paneling is only the skin of the wall. Behind the skin is the skeleton; two-by-four wood or metal "studs" running vertically from the floor to the ceiling in walls and two-by-six or larger "joists" running horizontally in the ceilings and floors. In between the studs and the joists is the space for the wiring and plumbing of your home. Exterior walls are different. They must insulate the house from the heat and cold outside, so they are stuffed with insulation. The national building code requires that the hollow wall space in exterior walls be broken by a horizontal stud placed between the vertical studs. This "fire blocking" makes it very difficult to retrofit long lengths of wire. In some areas of the country the exterior walls are constructed of solid masonry, and have no hollow space for speakers or wires. Start by examining all the possible routes you might take to run the speaker wire from the speaker to the volume control and back to the stereo. Use a stud sensor or other device to locate the internal structure of the wall. A typical route would be: from the speaker location up the inside of the wall to a new hole drilled into the top "plate" (horizontal two-by-four at the top of the inside of the wall), into the attic crawl space, then down to the volume control location through another top plate, back up to the attic, across the attic, and finally down another plate to the wall behind the Installation Fundamentals Speaker Location Volume Control Location Stereo Location Figure 9 11 Installation Fundamentals 12 Unobstructed space for speaker wiring Figure 10 stereo system itself (See Figure 9). The other very common route is through the bottom plate of the wall into an unfinished basement or crawl space. Identify where all of your electrical, phone, and TV wiring is likely to be and plan to route around it all. You can accidentally induce 60 Hz hum on your speakers if you run your speaker wire right beside electrical wire for more than a few feet. Try to keep speaker wire running parallel to power cables at least 3 feet away.
