WIRING INFO - 8 OHM OPERATION
Tap Setting Knob
When using the subwoofers
with a low impedance
system (such as with a 4Ω
or 8Ω amplifier or receiver),
make sure that the tap
setting switch is set to the
8Ω position. This is the only
appropriate setting when
using the speaker with a low
impedance amplifier.
Prewiring
Run a separate 2-conductor stranded copper speaker cable of at least 16 AWG
(1.5 mm) from the amplifier to each speaker.
When running a speaker cable parallel to an AC power cable, keep them at
least 24 inches (60 cm) apart to minimize electromagnetic interference. If the
speaker cables must cross AC wiring, cross them at right angles.
Leave about 2 feet (0.6 m) of cable at each end for connecting to the speakers
and amplifier. Label the cables so you will know which cable connects to each
keypad or amplifier output channel.
• Avoid running speaker wires close to house electrical wiring for any
distance. If you have to run them parallel, leave two feet between the
wiring. Speaker wires should cross AC lines at a 90° angle.
• The entire path between speakers and amplifier should be clear and
unobstructed. Confirm the placement for the wall port close to the
intended location of the amplifier or receiver.
• Label speaker wires at each end with left and right and location.
Impedance matching for amplifiers and speakers
If you intend to use more than one pair of speakers at a time it’s important
to consider both the impedance of the speakers and the capabilities of the
amplifier or receiver. Not all amplifiers or receivers can safely operate two sets
of speakers at once.
Connecting the speaker
With power to the amplifier or receiver disconnected:
1. Strip 1 to 2 inches (2.5 to 5 cm) off the end of the cable jacket. Then strip ½
inch (1.3 cm) of insulation off each wire.
2. Twist the wire strands together so there are no strands separated from the
bundle.
3. Connect the wires to the speaker terminals, being sure to observe proper
polarity. For standard speaker cable with red and black wires, connect the
red wire to the red positive (+) terminal and the black wire to the black
negative (–) terminal.
Note:
Some speaker cables may have other ways of designating polarity.
Cable with a clear jacket has a copper-colored wire for positive and a silver-
colored wire for negative. In a cable with white and black wires, the white is
positive and the black is negative. Cable with both wires the same color may
have grooves, ribs, or stripes on the positive wire.
4. Check to make sure there are no stray strands of wire outside the terminals.
If there are, remove the wire, twist the strands together, and reconnect the
wire to the terminal.
