PREPARATION FOR INSTALLATION
Before dismantling your vehicle, we suggest you prepare
all your components, enclosures and wiring harnesses. It
increases efciency to have everything ready when each
component is installed.
STEP 1 – CONFIRMING POWER TO BUSBAR
(Applies to 2013-2018 RZR Models)
The Polaris RZR and the MB Quart RZR-Tuned Audio
System upgrade requires a harness that connects the
battery under the seat to the busbar harness located under
the hood.
The harness is shown in Figure 1-1. Check that your
2013-2018 machine has this harness installed. If not, you
can purchase from your dealer or Polaris online. The part
numbers are 2881551 or 2881646 depending on which
specic RZR model you own. 2018.5 Turbo S and all 2019+
RZR models already contain a busbar harness.

STEP 2 - PREPARE KICK PANEL COMPRESSION HORNS
Figure 2-1
Do not proceed with the kick panel installation until you have properly prepared the speakers with their
compression diaphragm covers.
Refer to the manual in the kit called MBQ-POD. You can also nd this manual online by searching the model
number.
STEP 3 - SUBWOOFER ENCLOSURE & MOUNTING CLIPS
STEP 3a – LOCATE MOUNTING CLIPS
If your subwoofer is not pre-installed in the enclosure, you must
prepare the unit by installing the clips that hold the door from
your OEM glove box. See Figure 3-1.
Figure 2-1 is from the MBQ-POD manual which guides you
step-by-step through preparing the kick panel compression
horn speakers for installation into the kick panel enclosure
and the RZR.
Removing the large back plate and installing the special
compression horn diaphragm covers dramatically reduces
the depth of the compression horns which ultimately allows
our overall kick panel enclosure to be shallower than you
would think. This assures maximum leg room for driver and
passenger in the vehicle.
STEP 3b –MOUNT CLIPS
Mount the included hinge brackets for the OEM glove box door
to be tted on to your subwoofer as shown in Figure 3-2 through
3-4. Use the provided nuts to secure the hinge brackets from the
inside of the subwoofer. Do not over tighten.
The hinge clip with the closed hole mounts on the driver side
with the screws on the inside where the glove box door will
cover the screws. See Figure 3-3.
PRE-INSTALLATION
The hinge clip with the open (hook-like) hole mounts on the
passenger side with the screws on the inside where the door will
Set your subwoofer enclosure on a at surface as shown in Figure 4-1. *If you have a 2018.5 Turbo S
or 2019 RZR model, please see the modication required on the next page BEFORE completing the
subwoofer installation into the enclosure.
Put the subwoofer enclosure on its back
and extend the harness from inside
the enclosure as shown. This will allow
you to easily connect the wiring to the
subwoofer’s push-connector terminals.
Figure 4-1
If your subwoofer was not pre-installed, you will wire the woofer
with the dual voice coils to yield a 2 ohm load (indicated with the Ω
symbol) as pictured in Figure 4-2.
Figure 4-2
SUBWOOFER PREP
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 maximum power from the amplier by perfectly
balancing the impedance with the amplier’s power output.
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 Figure 4-3 and Figure 4-4.
NOTE – Wiring code is solid white connects to the (+) Positive/Red
speaker terminal and White/Black Stripe connects to the (-) Negative/
Black speaker terminal. To open the speaker terminals push down on
the connector to open, push the soldered ends of the wires 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 difcult to balance
the subwoofer enclosure and screw in the speaker for one person
shown in Figure 4-5.
Figure 4-3
Dual wire on one side.
Figure 4-4
Single wire on opposite side.
To avoid damage to the subwoofer, consider having a friend hold the
enclosure steady while you mount the subwoofer using hand tools
and the screws provided.
It is not advised to use a powered screw gun for this step.

Figure 4-5
REMOVE & REINSTALL THE GLOVE BOX DOOR
With a small amount of pressure you can bend up on
the center portion of your OEM glove box door and
remove it from the brackets.
In a reverse movement you can now reinstall this
door onto your new subwoofer glove box to give your
subwoofer a stealth appearance as shown in Figure
5-1.
The subwoofer is now complete. Set aside the
subwoofer enclosure/glove box combination until it’s
time for installation and amplier wiring.
NOTE – Once the subwoofer is ready to be installed, ensure the wiring harness from the subwoofer
enclosure that connects to the amplier 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 during
reassembly. The harness should be routed over the top of the push bar frame to the subwoofer amplier
connector. This is also noted in the subwoofer installation section, but important to consider at this stage.
Figure 5-1
SUBWOOFER ENCLOSURE MODIFICATION (2018.5 Turbo S and 2019 Models)
If you have a 2018 XP Turbo S or 2019 RZR XP vehicle, a simple modication to the subwoofer enclosure
which involves cutting four threaded metal studs and grinding them smooth is required. This modication in
no way will affect your product warranty. Complete this modication BEFORE loading the subwoofer into the
enclosure.
PREPARATION - You will need a at surface on which to work and someone to assist you in holding the
enclosure. You’ll also need a cutting tool (such as an Air Saw, Hacksaw, Sawzall) and a metal grinding tool
(such as a Dremel tool, electric disc grinder, etc.). Of course eye protection and heavy gloves are a must for
safety. Total modication time should be 10-15 minutes.
STEP 1 – IDENTIFY METAL STUDS TO BE CUT
Due to change in the metal work in the dash, the 4 front

RZR XP, XP Turbo and Turbo S machines as shown
in Figure 5-2. This is necessary for installation into the
vehicle later in the process.
STEP 2 – CUT OFF METAL STUDS
These 4 studs need to be removed with a cutting tool
(Air Saw, Hacksaw, Sawzall, i.e) or what other cutting
device that you would like to use.
STEP 3 – GRIND SMOOTH

STEP 1 – REMOVE SEATS
Remove driver and passenger seats by pulling on the lock clip shown in Figure 8-1. This lock clip is located
between the bottom and upright portion of the seat.
Behind the seats in the center of the machine is the panel where you access the oil lter. You will need to
remove this as shown in Figure 8-1b in order to feed and secure the rear speaker harness if not routing the
rear speaker harness inside the body panels.
Figure 8-1aFigure 8-1b
STEP 2 - UNBOLT AND MARK CENTER CONSOLE HARDWARE
Use the painters tape to mark where you remove each of the push pins and/or T-40 screws in the seat
side and seatbelt area as shown in Figure 8-2a. Remove and mark the nal T-40 screw at the front of the
console. We recommend using small disposable cups or sealable sandwich bags to label the different
screws in order keep track of them for reassembly.
DISASSEMBLY
STEP 3 - REMOVE CENTER CONSOLE
Gently push the shifter and seat belt boots back through
the console as show as shown in Figure 8-3. Carefully
remove center console from vehicle. Set aside in a safe
location until it’s time for reassembly.
Before positing the system harness and wiring all the components (source unit, ampliers, subwoofer and
other speakers), you need to prepare the power portion of the audio harness and run into the vehicle.
STEP 1 – REMOVE RZR Busbar FACTORY CONNECTIONS
Remove the connections to the RZR busbar as shown in Figure 9-1 to allow connecting the audio harness
along with reconnecting the RZR busbar harness.
STEP 2 – LAY IN HARNESS - IDENTIFY FIREWALL GROMMET
Beginning at the RZR busbar, route the power, ground and accessory portion of the audio system harness
in the front vehicle. The harness will run through the grommet next to an existing wiring harness as shown in
Figure 9-2. Do not use other grommets if present, empty or not. Use only the grommet shown.
Figure 9-1
STEP 3 – CUT OPENING IN GROMMET AND RUN WIRING THROUGH
Using a razor knife, carefully slice the rubber grommet on the top side as shown in Figure 9-3a. This allows
you to move the harnesses into the dash and to the ampliers. Push the radio, rear speaker/illumination
and amplier connections through the grommet as in Figure 9-3b. Leave accessible from the inside of the
vehicle. Use black electrical tape or silicone-based caulking to seal the slice during nal inspection.

STEP 4 – COMPLETE BUSBAR CONNECTION
Complete connections at the busbar as shown in Figure
9-4. Mount the MB Quart audio harness rst, with the
OEM RZR connections on top. This allows you to use
the red boot on the powerline, keeping your install clean
and looking factory installed. Zip tie this power portion
of the harness into place. Assure that no added wiring
is near any moving parts or components that generate
large amounts of heat.

AMPLIFIER PREPARATION AND MOUNTING (2013-2018 Models)
Before installing the dual amplier plate with the amplier(s) in position, you must prepare the mounting area
in the vehicle to accept the plate.
NOTE - These instructions assume both ampliers and all speakers are present in a full Stage 5 System. If
not all components are present in your system, this makes upgrading much easier.
STEP 1 – LOOSEN STEERING COLUMN NUTS
Loosen the 16mm nuts that secure the steering column to the support frame shown in Figure 10-1a. These
nuts are very hard to loosen. Be careful. Do not remove these steering column nuts, only loosen to create
an 1/8 inch gap between the nut and the frame shown in Figure 10-1b. You will not re-tighten these nuts until
the installation of the whole system is nalized, tested and the vehicle is ready for reassembly.
1/8” Gap
1/8” Gap
Figure 10-1aFigure 10-2b
STEP 2 – AMPLIFIER MOUNTING
Mount your amplier(s) on the dual amplier plate as shown in FIG 10-2 (below). This conguration is critical
to make sure you can access your ne tune adjustments for crossover and bass boost.
STEP 3 – MOUNTING PLATE INSTALLATION
With the ampliers mounted to the plate, slide it into position with the double groove portion of the bracket
sliding between the steering column support shown in 10.1b (above) and the 16mm nuts and washers. Do
not tighten down yet. On the front edge you will secure the plate with the 10mm bolt you removed from the
dash pocket which will also hold the bracket then will ultimately support the new dash pocket with the source
unit. The nished plate should look like Figure 10-3.

Figure 10-2Figure 10-3
You will tighten the 16mm nuts and washers next to the steering column once reassembly of the vehicle
begins. This allows easy removal of the amplier plate for troubleshooting (if necessary).
NOTE - The dual amplier harness is designed and laid out to perfectly connect power and speaker
connections on the driver’s side of the ampliers while the RCA audio connections are on the passenger
AMPLIFIER PREPARATION AND MOUNTING (2018.5 Turbo S & 2019 Models)
Before installing the dual amplier plate with the amplier(s) in position, you must prepare the mounting area
in the vehicle to accept the plate. The area where the ECU bracket was removed and set aside is where the
dual amplier plate installs. If a factory-optioned amplier was present, this would also have been removed.
NOTE - These instructions assume both ampliers and all speakers are present in a full Stage 5 System. If
not all components are present in your system, this makes upgrading much easier.
AMPLIFIER MOUNTING
STEP 1 – SET THE ECU AND BRACKET BACK IN
PLACE*
Set the Dynamics ECU (if present) and ECU mounting
bracket back in its original placement ensuring the wiring
intended for the amplier harness is routed through the
gap area at the forward section of the bracket. Loosely
reattach only the two (2) 10mm rear bolts (nearest the
dashboard) at this point as shown in Figure 10-4. *It is
only important the ECU bracket is back in place for trial
tting of the dual amplier plate. It will not have its nal
reassembly at this step.
STEP 2 – AMPLIFIER MOUNTING
Mount your amplier(s) on the dual amplier plate in
the conguration shown. This conguration is critical to
make sure you can access your ne tune adjustments
for crossover and bass boost.
STEP 3 – TRIAL FITTING THE DUAL AMP PLATE
With the ampliers mounted to the plate, place it into
position atop the ECU bracket as shown in Figure 10-6.
Be sure there is free movement of the wiring harness
with enough length to connect to the amplier’s onboard connectors. Loosely t the remaining two (2)
10mm bolts from the ECU bracket to check the t of the
dual amp plate. Connect the power and speaker wiring
to the harness as labeled. Do not zip tie anything at this
point as the amp plate will not have its nal reassembly
With the ampliers connected to the wiring harness,
place a towel or blanket over the open hood area.
Remove the rst two (2) 10mm bolts for the amp plate,
remove the plate and ip it over on the towel to avoid
scratching the amplier heatsinks. Next remove the
remaining two (2) 10mm bolts from the ECU mount (if
present) and place the ECU to the side as when initially
disassembled on page 10. This will allow you to continue
working on the other steps of the installation until you’re
ready to power up the system, complete nal testing and nalize the reassembly of the ECU bracket and
dual amp plate.

SUBWOOFER ENCLOSURE MOUNTING (ALL MODELS)
With the subwoofer installed in the enclosure and the glove box door in position from earlier preparation
steps, you are ready to mount the subwoofer into the glove box location. For those applications on 2018.5
Turbo S and 2019+ RZR models, ensure you’ve completed the modication shown on page 6.
STEP 1 – POSITION AND BEGIN MOUNTING SUBWOOFER_ ENCLOSURE
Sitting on the oor of the RZR, hold the subwoofer enclosure up to the grab bar pipe. Sitting on the oor
of the RZR, hold the subwoofer enclosure up to the grab bar pipe. Mount the subwoofer to the RZR using
the supplied steel plates (2), the (8) nuts, and
(8) washers shown in Figure 11-1. Use your
1/2 inch socket with a small ratchet to begin
tightening the nuts. Space is tight for any larger
tools, a smaller ratchet will work best.
NOTE – Ensure 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 amplier connector.
Figure 11-1
STEP 2 – FINISH SUBWOOFER MOUNTING
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 enclosure comes
up against the grab bar pipe, before it is nally
secure, make sure that the speaker wire is not
behind the enclosure. Once veried, bolt the
subwoofer tightly into place.
NOTE – When the subwoofer starts to seat
into place, push the subwoofer rmly forward
as shown in Figure 11-2 as you tighten the last
thread with the mounting nuts. This forward
pressure will be critical when you reassemble the front
dash for tment into all the clips.
STEP 3 – ROUTE SUBWOOFER HARNESS
Route the subwoofer enclosure’s harness over to the
SUBWOOFER MOUNTING
amplier area. Connect it to the speaker output of the
mono amplier as shown in Figure 11-3.
Figure 11-2
Push Forward While Tightening
Mono
Amplier
Figure 11-3
The next section describes connecting the other wiring
With your amplier(s) mounted, subwoofer installed and connected to the mono amplier, you can now
begin laying in the front/rear speaker harnesses and plugging in all the remaining connectors.
NOTE - While you are working on your system, we recommend covering the ampliers to avoid scratching
them or inadvertently hitting the crossovers with a wrench or screw driver.
STEP 1 – POWER AND SPEAKER CONNECTORS AT AMPLIFIERS
Plug in the power/ground connector of the two channel and the mono ampliers
respectively. At the same time, if you have illumination, connect the red/black. Next,
connect full range speaker connectors to the two channel amplier. You should
already have connected the subwoofer to the mono amplier in the previous section.
If not, do this step now. See Figure 12-1 for the connection diagram.
STEP 2 – ROUTE FRONT SPEAKER HARNESS
Make sure your front left and front right kick panel
Figure 12-1
harnesses are set into place.
The left front harness for the kick panel should be
routed down the left side of the steering column to
the kick panel area.
HARNESS CONNECTIONS
The right front harness for the kick panel needs to
be routed over the subwoofer, not behind, and then
to the kick panel area.
The kick panel pod installation will take place at a
later step. For now, you are simply pre-wiring the
harnesses to their respective areas.
STEP 3 – ROUTE REAR SPEAKER HARNESS
Route rear speaker harness toward rear speakers
through the console area as shown in Figure 12-2.
You can route the remaining harnesses to the rear
pod area by either removing the oil lter cover on
the back wall or route your wires through small
gaps in the body panels.
NOTE – On a four seat RZR (4P RZR) you will need to include the 4P jumper to extend the rear speaker
harness, past the rear seats and then to the rear pod area. See Figure 12-3 for connection.

REAR SPEAKER POD INSTALLATION
Every roll cage angle is a bit different; therefore you should take the time to install the swivel mount
brackets. We suggest you do this on a at surface or work bench.
These brackets are designed to allow 180 degree tilt. This
guaranties that the speaker points directly forward. This exibility
in positioning improves sound quality and overall volume. Refer
to instructions for the swivel bracket packaged with the speaker
pods. Also ensure that the Adjustment Locking Screw is at the
rear of the assembly (not the front) as shown in Figure 13-1.
STEP 1 – TEST MOUNT SPEAKER PODS w/BRACKETS
Stock RZR roll cages use the 1.75 inch tube. If you have an
aftermarket or custom cage you will nd the correct bushings and
mounts included in the box with the pods. Refer to the manual
included with your pods for additional details on mounting and wiring.
Mount the pod and swivel bracket to the roll cage tube. Once the speakers are on the roll cage tube, you
can gently slide the pod up or down on the tube to determine where your nal height will be. Use painter’s
tape to measure and mark a general position so it’s even on both sides. Figures 13-2a and 13-2b show
potential mounting options to try out.
Figure 13-2aFigure 13-2b
SWIVEL STRAIGHT
This position offers
MAXX volume
This position will have less
volume to riders in the RZR
Figure 13-1
SWIVEL DOWN
Once the general mounting position is chosen, do not fully tighten the pods as you may want to do nal
adjustments for your ear height after the seat is in position and the system is playing music.
STEP 2 – CONNECT WIRING
Wire up the rear speaker wiring to the speaker pods. If your pods also feature illumination, connect those
wires as well. The harness ran in the vehicle should be color coded and have the correct male/female
REAR SPEAKER PODS
connectors to make this an easy task.
Do not zip-tie the wires along the roll cage or gather up excess wire until the system has been fully tested.
Through hundreds of installations, we’ve found once mounting holes are drilled, it’s best to start with the
driver’s side kick panel and then move on to the passenger’s side kick panel to complete the mounting and
wiring of the kick panels. This way you only need the drill out once, then completely nish the left before
moving on to the right. The subwoofer should already be mounted at this stage and both kick panel wires
run to their respective general areas.
STEP 1 – MARK DRILLING SPOTS ON FENDER
Using colored painters tape shown in Figure 14-1a, to mark the interior fender well of the RZR where you
need to drill two mounting holes. To do this, hold an empty left or right pod in your hand. Hold the pod
into place to approximate the position of the mounting holes on the internal fender. Set the unit down and
put colored tape onto the interior fender well area behind the pod until you can see the tape through the
mounting holes when you hold the pod back into place. Next, use a permanent felt-tipped marker to mark
the mount holes on the painter’s tape as shown in Figure 14-1b. Repeat this process on the passenger’s
side kick panel area.
Figure 14-1a

Figure 14-1b
STEP 2 – DRILL HOLES
Drill (2) 5/16 inch mounting holes into the fender where you marked the tape shown in Figure 14-2. Repeat
this process and drill two more 5/16 inch mounting holes on the passenger’s side kick panel area. Remove
any tape in the drilling area from the interior fender wells.
STEP 3 – PUSH OUTER BOLTS THROUGH FENDER AND KICK PANEL
With the included hardware push (1) bolt and (1) washer mount through the fender into the pod. This leaves
only the head of the bolt visible behind the tire shown in Figure 14-3.
Figure 14-3
Figure 14-2
NOTE - Wait to mount passenger kick panel until driver’s side
panel is completely mounted and wired.

STEP 4 – MOUNT KICK PANELS
Using the 5/16 inch bolts, washers, and nuts, mount
the kick panel as shown in Figure 14-4. Make sure you
use a washer on the inside of the enclosure against the
internal wall of the pod which you sandwich against the
fender of the RZR. Use your 1/2 inch ratchet and wrench
to secure the pod.
NOTE - Make sure that the wires behind the enclosure
have remained accessible for connecting to the amplier
harness. Use some painters tape to keep them from
getting blocked by the enclosure if necessary.
STEP 5 – CONNECT WIRE HARNESS INTO KICK PANELS
Connect the wire harness from the amplier that you routed earlier to the wire harness from the kick panel.
STEP 6 – WIRE THE FRONT SPEAKERS
Identify the harness wires from inside of each pod and connect the wires to the back of the compression
horn speakers as shown in Figure 14-5a. Connect speaker wires as shown in Figure 14-5b. If your kick
panel speakers also feature illumination, connect those wires as well.

STEP 7 – MOUNT THE FRONT SPEAKERS
With the speakers properly wired, mount the speaker to the enclosure. Position the speaker (with the
compression horn backplate removed) in the enclosure and mount with the included hardware as shown in
Figure 14-6a. We suggest mounting with hand tools to stripping out the mounting hardware or damaging the
speakers. Final speaker position is shown in Figure 14-6b. Repeat steps 3-7 on the passenger’s side.

SOURCE UNIT PREPARATION
This applies to non-Ride Command-equipped vehicles. If your RZR is equipped with the Ride Command
system, you will use that as the vehicle’s source unit and this requires additional purchase of two adapters
(part number RC1-2RCA-F ) to provide signal and turn-on to the MB Quart ampliers. The MB Quart source
unit is not required to be used in Ride Command-equipped applications.
Make sure you have removed the metal clip from the OEM dash pocket
mentioned in the disassembly section of this manual. It’s required for mounting
the new source unit mount to the RZR. See Figure 16-1.
Figure 16-1
STEP 1 – PREPARE MOUNTING COMPONENTS
Working on your bench or another at surface, ensure
you have all the necessary hardware to install the
source unit into the dash plate adapter shown in Figure
16-2. Refer to the manual included in the source unit for
detailed mounting instructions.
Figure 16-2
Figure 16-3aFigure 16-3b
SOURCE UNIT PREP
\STEP 2 – MOUNT SOURCE UNIT USING BRACKET
Insert the long threaded bolts with the molded bolt closest to the source unit. When set face down, the
source unit should look like Figure 16-3a. Once the mounting bolts are secured, place the source unit
through the opening of the pocket replacement panel.
Next secure the bracket over the bolts and thread on the
remaining nuts to snug the bracket against the back side
of the panel as shown in Figure 16-3b.
STEP 3 – MOVE METAL CLIP TO SOURCE MOUNT
Locate the OEM metal clip from the dash pocket and
move it to the top side of the source unit’s mounting
INSTALLING THE SOURCE UNIT (Non-Ride Command-Equipped)
Reassemble part of the front dash around the dash pocket area. Utilize the reverse method of how you
removed the center section of the dash pocket. This will allow the source unit mount to be to be installed in
place so the harness can be nished and connected in the proper location. Final tting and reassembly of all
panels is the last step of the installation after testing the system.
STEP 1 – RUN CONNECTIONS TO SOURCE UNIT AREA
Run the (2) RCA audio cables from the amplier location into the area where the source unit will be installed.
Be sure to observe left and right channels at the amplier. Make note of which connects to the two-channel
amplier and which connects to the mono amplier.
Next, if not already done, run the source unit connectors to the area where the source unit will be installed.
STEP 2 – MAKE SOURCE UNIT CONNECTIONS
With the harness routed through the vehicle and everything
Figure 17-1a
connected to the amplier(s), the next step will be to
make the nal source unit electrical and RCA audio cable
connections in the dash as shown in
Figure 17-1a. Raise the completed source
unit mount to the dash area. Connect the
Mono
Amp
Two-
Channel Amp
electrical (Delphi-style) connector. Connect
the front RCA preamp level outputs to the
two-channel amplier. Connect the rear RCA
preamp level outputs to the mono amplier.
SOURCE UNIT INSTALL
Figure 17-1b
Figure 17-1c
Depending on the style of remote turn-on present on your source unit, follow Figure 17-1b for the
connection. Figure 17-1c shows the connections to the source unit in the dash.
NOTE – As you raise the completed source unit to the dash area, ensure you retained and installed the
metal clip described in the previous section.
STEP 3 – SECURE THE SOURCE UNIT
Push the dash assembly into place until you feel
and hear a snap as the entire assembly seats
into place. The nished look should cosmetically
resemble Figure 17-2.
Powering up the system and initial testing will be in
a subsequent step.

MOUNT THE USB & 3.5mm (AUX) DASH ADAPTER
Every machine and more importantly every RZR owner is different.
With the STAGE Tuned Audio packages, we include a dual
input dash adapter. This means that no matter how you connect
your audio system or which RZR you have, you have plenty of
connections.
STEP 1 – CHOOSE A LOCATION
Select a location for the USB/3.5mm adapter somewhere in the
vehicle that is accessible, but not too low in the vehicle where
it can be submerged in deep water. Due to the rubber gaskets
included for the front and the back of the mount all you need is a
small smooth surface on which to mount. If you are not installing
a subwoofer in your system, inside the glove box is a good
installation location.
STEP 2 – DRILL HOLE
Before drilling, check behind the location for adequate depth of at least 2 inches. Drill a 1 inch hole in the
substrate of your chosen mounting location.
USB/AUX Adapter Dimensions
STEP 3 – MOUNT ADAPTER
After you have drilled the hole in the mounting surface,
make sure to pull all the wires through the rubber
grommet with the small “door” for the front. This seals
the USB and 3.5mm (AUX) input on the front face.
Additionally, there will be a rubber grommet on the rear of
the mounting surface, all secured by the large nut as in
Figure 18-1.
NOTE – The large thumb nut only needs to be nger
tight. Two rubber grommets help the unit seal to the
mounting surface.
Figure 18-1
USB/AUX ADAPTER
STEP 4 – CONNECT TO SOURCE
There is a 10 foot (3.0 meters) cable that extends the
USB and AUX input from your source unit. After mounting
the adapter as demonstrated in Figure 18-2, run the
cable to the source unit and connect the USB to the
source unit connector and the 3.5mm RCA connectors
to the source unit AUX-1 input. After the TEST & TUNE
process is complete, zip tie and secure any excess cable
Nearly done, but it is smart to conrm that everything is working before you put the machine back together.
STEP 1 – RECONNECT THE BATTERY
With the harness connected to the busbar, you can now
reconnect the negative terminal of the negative battery
cable as indicated in Figure 19-1.
STEP 2 – TURN ON IGNITION
Turn the ignition key to the ACC position and push the
PWR button on your source unit.
STEP 3 – INITIAL CHECKS
The following instructions are for conrming connectivity
of the system you just installed. Refer to the full manual
for the source unit to use features like Bluetooth® pairing, adjusting treble and bass or working with the EQ.
Here is a check list so you know you did not forget something.
With the power “ON” use the list here to check the system for all of the following. Make sure you are using
the controls on the source unit to conrm Left is the left-side channel and right is the right-side channel.
There will be no change on the front/rear speakers as fas all speakers are on the same two-channel
amplier.
● POWER ON - Source unit lights up and responds to button presses
● USB INPUT (if used) responds when selected
● AUX 3.5mm INPUT (if used) responds when selected
● BT MUSIC - Follow the pairing instructions in your source unit and test a Bluetooth® source.
● AM/FM RADIO - Unless you have installed and AM/FM antenna, you will only hear static.
● SPEAKERS - Conrm all speakers play the correct range of frequencies (lows coming from the
subwoofer, mid to high coming from front and rear speakers).
● AMPLIFIERS - If the speakers are playing, the ampliers are on. Conrm settings are correct if something
doesn’t sound exactly right. CONFIRM ALL YOUR SPEAKERS AND AMPLIFIERS ARE CONNECTED
CORRECTLY

FINE TUNING
After you have conrmed and tested that all components are working you will tune the ampliers. When
setting up your ampliers you will refer to the manual inside each amplier. However, through hundreds
of installations we have determined the following settings are ideal for the following STAGE Tuned Audio
Packages.
NOTE – Gain control, it is important to adjust each amplier gain as described in the manual. Remember,
these settings are NOT volume controls. Gain controls, properly adjusted help properly balance the system
sound between lows, highs and minimize distortion that comes from the source unit. Listen for a clear, crisp
audio sound. The ideal gain setting should allow full volume from the source unit without audible distortion.
FINAL AMPLIFIER MOUNTING (2018.5 Turbo S & 2019 Models)
Now that the system is tested and tuned, if you have a 2018.5 Turbo S or 2019+ model RZR, you’ll now be
ready to nalize the amplier mounting and complete the install.This will be much like the earlier trial tting
on page 15, but the hardware will be fully tightened and the wiring zip tied neatly in place.
STEP 1 – SET THE ECU AND BRACKET BACK IN PLACE
Set the Dynamics ECU and ECU mounting bracket (if present) back in its original placement ensuring the
wiring intended for the amplier harness is still routed through the gap area at the forward section of the
bracket. Replace the two (2) 10mm rear bolts (nearest the dashboard) as shown in Figure 20-1 and fully
tighten them.
Figure 20-1

STEP 2 – FINAL FITTING THE DUAL AMP PLATE
Carefully place the amplier plate into position atop the ECU bracket as shown in Figure 20-2. Be sure the
wiring harness and connectors are all intact and nothing has come unplugged. Replace the remaining two
(2) 10mm bolts from the ECU bracket to secure the dual amp plate in its nal position.
Figure 20-2

STEP 3 – SECURE WIRIING HARNESS
Secure the wiring harness with zip ties to complete the installation. Ensure the routing of the harness avoids
contact with any sources of heat or moving parts. Should the ECU (if present) ever need servicing, be sure
to leave enough slack in the harness so that the amp plate can be removed and either set aside or ipped
over as it was during intial tting.
27
VEHICLE REASSEMBLY
Follow along the dual amplier audio harness and zip tie the harness to the machine to assure it doesn’t
come loose during rides. Do not zip tie the harness to any heat or moisture sources. Also ensure the point
at which the harness passes through the lewall grommet is sufciently sealed with electrical tape, siliconebased caulking or equivalent. Once your harness is secure and the rewall grommed is sealed, you can
begin reassembling all the panels.
Here is an important checklist so you do not forget anything:
