Preparation

You also need to observe safe and practical standards:

WARNING: Make sure the spot chosen is safe for drilling. Do not drill through surfaces that may have hazards, such as electrical wiring, conduits, or plumbing concealed behind them. Follow all other safety precautions.

•Consult local building codes to inform yourself of the requirements in your area.

•Use a drill bit large enough for the cord you will pull through the holes.

•Use an auger bit, if possible, to make the work of drilling multiple holes less tiring.

•Do not drill through a load-bearing beam. Consult the building contractor if this is an issue.

•Keep the cord 3 to 4 feet (1 to 1.3 m) away from electrical cord, which can create a hum or buzz in the speakers (Figure 10).

•To avoid nails, drill holes in the center of each stud or joist.

•Use a nail plate to protect the cord if your only option is to notch a stud or joist.

•Line up holes as perfectly as possible to make pulling the cord through easier.

•Keep the cord taut enough so there are no sags.

•Do not pull the cord tight enough to create tension.
