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, remov- ing the cover plate and switch or recepta- cle, 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).
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).
