WIRING FOR NEW CONSTRUCTION
For best results, avoid running speaker wire near AC wiring, as it may induce a 60Hz hum in the
audio signal. It's a good idea to run the speaker wire after the electrical wiring has already been
completed, so that you can route the speaker wire at least three feet away from the electrical
wiring. If speaker wire and AC wiring must run parallel, install the wire within a metal conduit.
NOTE: THE SW10JM IS DESIGNED FOR INTERIOR IN-FLOOR OR IN-CEILING INSTALLATIONS
BETWEEN STANDARD JOISTS 10" TALL OR GREATER. INSTALLATION IN OUTDOOR LOCATIONS OR
IN MOISTURE-PRONE INTERIOR ENVIRONMENTS SUCH AS INDOOR SWIMMING POOLS OR SAUNAS
IS NOT RECOMMENDED.
CAUTION: ALWAYS CHECK FOR ELECTICAL/HEATING/PLUMBLING APPARATUS BEFORE CUTTING INTO
CEILINGS OR FLOORS.

The SW10JM has 5-way binding posts that accept all
types of wire ends.
Be sure to wire the subwoofer "in-phase"— positive
(red) terminal on the amplifier output must be connected
to the corresponding positive (red) terminal on the
subwoofer and likewise negative (black). Most speaker
wires have markings along one or both conductors to
help you make the correct connections. Take care to wire
the subwoofer correctly in-phase, before floors/ceiling
are sealed.
