subwoofer into the hole and verify that it is horizontal using the bubble level. It is
now time to connect the loudspeaker wires to the subwoofer. Before connecting
any loudspeaker wire, make certain that the subwoofer amplifier is turned OFF.
Connect the loudspeaker wires to the subwoofer, making certain to match polarity
so that the positive lead from the amplifier matches to the positive lead from the
subwoofer and do the same with the negative leads. When connecting the wires,
be sure to use silicone filled wire nuts, or an appropriate water tight connector or
junction box.
Connect the wires to your subwoofer amplifier and turn it on to test the
connection. If the loudspeaker sounds fine, you can now fill in the hole around
the GSS10. Keep in mind that the subwoofer will sound slightly different when
fully installed in the ground than it will in an open air environment. Verify the
satisfactory performance of each loudspeaker before covering any exposed
trenches or conduit used for your wiring.
Before proceeding, turn off the amplifier for safety.
Carefully pack and compress the dirt around the subwoofer making certain not
to damage either the subwoofer or its wiring. The subwoofer should have firm
support on all sides to prevent any settling in the future.
Should you ever need to service your GSS10 subwoofer, you can use the
Niles Logo located on the top cover to determine where the unit is located
underground. The side of the vent cover with the Niles Logo (
) is the side
where the subwoofer unit is located.

The tube and its dome cover can be painted to match any environment. When
painting the GSS10 port tube, be sure not to paint the underside of the dome.
There are special filter screens that should not be painted over on the underside of
the dome. The top and sides can easily be painted with a high quality spray paint.
