INSTALLATION (CONTINUED)
locate the internal structure of the wall. You want to avoid all studs or joists. A typical route would be
from the sensor location up the inside of the wall to a new hole drilled into the top “plate”
(horizontal 2 x 4 at the top of the inside of the wall), into the attic crawl space, then down another
plate to the wall behind the stereo system itself. 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 interference on your sensor cable right beside electrical cable
for more than a few feet. Try to keep sensor cable running parallel to power cables at least 3 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 see which part of the wall space is free of obstructions (Figure 14).
