4. Mark the wall where the wire will pass through the plate,
and cut a small access hole large enough for the wire to
pass through without interference. Where the stud is
wider than the plate's access hole, cut the hole in the wall
to the left or right and directly alongside the stud (see
figure 7).
N Before cutting the hole in the wall, make sure the plate will
hide the hole after installation.
5 . Using compatible speaker wire (Extron recommends using
12-18 AWG), route the wire from the audio source to the
speaker location by the most convenient and safe route. If
the wiring is to remain hidden behind the wall, follow the
stud to where the small access hole has been cut, and feed
about two feet of wire out through the hole into the room.
If necessary, bend the wire behind the plate to align with
the hole in the plate (see figure 7). If possible, secure the
wire to the stud at various places. Allow enough freedom
of movement at the hole for speaker connection.
Cut an acess
hole alongside
the stud and
feed the speaker
wires though the
hole.
