PREPARATION
If your subwoofer was not preinstalled, you will wire the woofer with the dual voice coils to 2
ohms (indicated with the Ω symbol) as pictured in FIG 3-2. We have prepared the internal
harness so you cannot make a mistake. Wiring the subwoofer for 2 ohms (2Ω) will allow the
subwoofer to develop maxximum power from the amplifier by perfectly balancing the impedance
with the amplifiers power output.
(FIG 3-2)
Use the connection where two wires will insert into one voice coil connector and then route the
other end of the wire to opposite connector, shown in FIG 3-3 and FIG 3-4.
NOTE –Wiring code is solid white connects to the (+) Red terminal
and White/Black Stripe connects to the (-) Negative
To open the terminals push down on the connector to open, push the soldered ends through the
hole and release the connector to establish a good electrical connection.

STEP 2 –SECURE THE SUBWOOFER TO THE ENCLOSURE
Due to the shape of the enclosure it can be very difficult to balance the subwoofer enclosure
and screw in the speaker for one person shown in FIG 3-6.
Consider having a friend hold the enclosure steady while you mount the subwoofer using HAND
TOOLS with the screws provided.

CHAPTER 6 –MOUNT THE SUBWOOFER ENCLOSURE
With the glove box door in position and the subwoofer installed in the enclosure, you are ready
to mount the subwoofer back into the glove box location.
Sitting on the floor of the RZR, hold the subwoofer enclosure up to the grab bar pipe.
(FIG 6-1)
Mount the subwoofer to the RZR using the supplied steel plates (2), the (8) nuts, and (8)
washers shown in FIG 6-1. Use your ½ inch socket with a small ratchet tool to start to tighten
the nuts. Space is tight for any larger tools, a smaller ratchet will work best.
NOTE –Make sure the wiring harness from the subwoofer does not get pinched
behind the enclosure. This will prevent the enclosure from seating properly and
will not allow the front dash to snap into place properly.
The harness should be routed over the top of the push bar frame to the subwoofer
amplifier connector.

Tighten a few threads at a time on each bolt to allow the subwoofer to rise up against the pull
bar frame evenly. This will allow the subwoofer to seat properly against the frame of the vehicle.
As the subwoofer comes up against the bar, before it is finally secure, make sure that the
speaker wire is not behind the enclosure.
NOTE - When the subwoofer starts to seat into place, push the subwoofer firmly
forward as you tighten the last thread with the mounting nuts.
This forward pressure will be critical when you reassemble the front dash for
fitment into all the clips.
