NOTE: BE VERY CAREFUL WHEN LOCATING THE SPEAKERS. VERIFY ALL LOCATIONS ARE
CLEAR OF OBSTRUCTIONS BEFORE CUTTING THE FIRST HOLE.
Each speaker requires two-conductor wiring of sufficient gauge. The gauge depends
on the length of the wire. For recommendations, please refer to (Figure 2).
When running loudspeaker wire inside walls or ceilings, use special jacketed
cable (CL-2 or CL-3 rating) to protect the wire and for re prevention. In some
municipalities, conduit is required. For a trouble-free installation, low voltage wire
such as loudspeaker wire must be in accordance with the National Electrical
Code and any applicable provisions of the local building code. If you are unsure of
the correct installation techniques, wire jacket, or type of conduit to use, consult
a professional audio/video installer, building contractor, or the local building and
inspection department.
