WIRING THE SPEAKERS
If you wish to conceal the wire within the walls, it is easiest
to run the wires to their final positions prior to mounting the
speakers.
The spring loaded terminals of the MC650HD accept bare
wire between AWG #12 and AWG #18 (lower numbers are
thicker). It is not necessary to “tin” the wire or use connec-
tors to terminate the wire.
• Use at least AWG #18 speaker cable for short runs
(under 15 feet). Use AWG #16 or heavier speaker cable
for longer runs.
• Building codes typically require plenum rated wire for
installation within walls. Be sure to use wire that complies
with any applicable local building codes. Plenum rated
cable typically has an outer jacket with individually
insulated conductors inside the outer jacket. Some brands
of plenum rated cable may be too thick to fit the space
between the wall mount bracket and the speaker. To use
heavier plenum rated speaker cable with the wall mount
brackets, remove the outer jacket and any filler cord back
to the point where the wire exits the wall.
Preparing the wires:
1. Determine how long the speaker cable should be for
each speaker. Cut the speaker cable into the
appropriate lengths.
2. Route the wire to each speaker location.
3. Strip 1/2 inch of insulation from the two individual
conductors in the speaker cable. Twist the exposed
strands of bare wire together.
4. Determine which conductor you will use to connect the
positive terminals of the amplifier and speaker together.
Printing or a ridge on the insulation usually distinguishes
one of the two conductors. Sometimes the metal of the
conductors has two different colors, or the insulation
color of each conductor may be different.
