[. . . ] 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 loudspeakers or wires. Start by examining all the possible routes you might take to run the loudspeaker wire from the loudspeaker 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 loudspeaker location in the ceiling, across the attic, then down through a top plate (the horizontal 2x4 or 2x6 laid across the vertical studs) to the volume control location, back up to the attic, across the attic, and finally down another wall plate to a J-Box in the wall behind the stereo system itself (See Figure 8). 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 60Hz hum on your loudspeakers if you run your speaker wire right Installation Fundamentals 10 Loudspeaker Location Volume Control Location Stereo Location When you don't have access above or below the wall, try to estimate the existing wire and pipe locations from the positions of electrical outlets and plumbed fixtures on both sides of the wall. Take a look at the outside of your house too, sometimes conduit, vents or drain pipe will be visible that give useful information. Choose the route with the fewest potential obstacles. If your house is built on a slab or you are wiring between two finished floors, look for baseboards which could be removed and replaced with the wire behind them. Doorjambs can be removed and often have enough space for loudspeaker wire all the way around the door (See Figure10). Sometimes, an under-the-carpet run is possible (there are special flat loudspeaker wires made for under-the-rug wire runs). As a last resort, heating and air conditioning vents can be used as wire raceways for plenum rated wire (check your local building codes, some municipalities require conduit). Installation Fundamentals 11 Figure 8 beside electrical wire for more than a few feet. Try to keep speaker wire running parallel to power cables at least three feet away. To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turning off the breaker for a particular power outlet or switch, removing the cover plate and switch or receptacle, and shining a penlight into the wall. If you have access to an attic or basement space you can quickly see which part of the wall space is free of obstructions (See Figure 9). Unobstructed space for loudspeaker wiring Figure 9 In traditional wood stud/drywall construction you should first cut the hole for the loudspeaker and utilize the large hole to auger across the (through the ceiling joists) for as far as your drill bit will take you. Sometimes, you will need to use the "notching" technique to reach areas your drill bit won't reach or to turn corners (e. g. to go down the wall when there is not an accessible attic). Don't make an irregular hole in the drywall. If you carefully cut a rectangular hatch in the drywall you will make your patch at the same time you cut your hole. Notch the bottom of the joists and run the wire through the notches.
