Installing Your Speakers From The Front Of The Bulkhead
Attach the mounting flange to the enclosure using
B 6
six screws.
Slide this assembly into the 7
B 7
and rotate the enclosure a full 360° to determine the
best mounting position for the extended portion of
the speaker enclosure.
When you have determined the best position, take a
moment to make careful note of it. Then, remove the
speaker enclosure.
You will need to open one of the five marked drain holes
B 8
because water can enter your 131
through the ports on the front of the enclosure.
Holding the enclosure in the mounting position you
chose in Step 7, find the drain hole that will be at the
lowest point when the speaker is mounted and break
through the surface using a center punch, awl, or
inch (.32 cm) drill bit. Completing this task may require
you to temporarily remove the flange from the enclo-
sure.
CAUTION: Acoustic performance is reduced if the
hole is larger than inch (.32 cm).

Connect the speakers. Be sure the receiver or amplifier is
B 9
turned OFF. If possible, disconnect the power source.
Use the supplied silicone-filled wire nuts to secure the
ends of each wire pair. Place the stripped end of the
positive (+) right channel receiver wire together with the
stripped end of the positive (+) right speaker wire. Place
the wire nut over the ends of the wires and turn it in a
clockwise direction. Turn it with firm pressure until it stops;
there should be no uninsulated wire visible. Repeat this
procedure for the remaining wire end.
Repeat the above procedure for the left speaker.
Check that all connections are made positive to positive
(+ to +) and negative to negative (– to –). Tighten any loose
connections before you plug in the receiver or amplifier
and turn it on.
Note: Twisting the ends of the wires together is not
necessary.
