WHAT FITS MY VEHICLE?
TWO RZR-TUNED STAGE 2 AUDIO SYSTEM OPTIONS!
Depending on whether or not your RZR®vehicle has the optional Ride Command®system, you should have
selected the appropriate MB Quart Stage 2 audio system to suit your application.
ABOUT RIDE COMMAND®
All Polaris®RZR® vehicles up to 2017 do not have the Ride Command. It wasn’t
available as an option. From the 2017 RZR XP® 1000 EPS Velocity Blue Limited
Edition and later RZR model years, you can have Ride Command as an option.
VEHICLES WITH RIDE COMMAND®
If your 2017 or newer RZR model is equipped with the Ride Command system, the
MBQR-STG2-RC1-2 is the correct Stage 2 audio system for your vehicle. This system
does not include a source unit because you will retain the Ride Command system as the
source unit. MB Quart provides two vehicle-specic Ride Command adapters in this kit
to allow easy plug-in interface for connection to the amplier inputs in the Stage 2 system.
Throughout this installation manual, ensure the instructions you follow for installation
applies to your Ride Command-equipped RZR vehicle.
VEHICLES WITHOUT RIDE COMMAND®
If your RZR model is not equipped with the Ride Command system, the MBQR-
STG2-RAD-2 is the correct Stage 2 audio system for your vehicle. This system
includes the MBQR-RAD-2 digital media source unit in a vehicle-specic
housing intended to t in the storage pocket space at the center of the dash (once
the pocket is removed). Throughout this installation manual, ensure the instructions
you follow for installation applies to your non-Ride Command RZR vehicle.

POWER HARNESS
INSTALL POWER HARNESS AT BUS BAR (ALL MODELS)
You must prepare the power portion of the audio harness and run into the vehicle before wiring and
connecting any of the audio system components.
STEP 1 – REMOVE RZR BUS BAR FACTORY CONNECTIONS
Remove the connections to the RZR bus bar as shown in Figure 9-1 to allow connecting the audio harness
along with reconnecting the RZR bus bar harness.
STEP 2 – LAY IN HARNESS - IDENTIFY FIREWALL GROMMET
Beginning at the RZR bus bar, 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.
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 ampliers. Push the radio, rear speaker/illumination,
and amplier 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 the nal inspection.
STEP 4 – COMPLETE BUS BAR CONNECTION
Complete connections at the bus bar 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 MOUNTING
AMPLIFIER PREPARATION AND MOUNTING (2013-2018 Models)
Before installing the dual amplier plate with the amplier(s) in position, you must prepare the mounting area
in the vehicle to accept the plate.
NOTE - These instructions assume two ampliers and all speakers are present in a Stage 5 System. This
makes upgrading by adding a subwoofer and rear speakers easier. It’ll be prewired for those upgrades.
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.
STEP 2 – AMPLIFIER MOUNTING
Mount your amplier(s) on the dual amplier plate as shown in Figure 10-2 (below). This conguration is
critical to make sure you can access your ne-tune adjustments for crossover and bass boost.
STEP 3 – MOUNTING PLATE INSTALLATION
With the amplier(s) 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.
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 amplier plate for troubleshooting (if necessary).
NOTE - The dual amplier harness is designed to perfectly connect power and speaker connections on the
driver’s side of the ampliers while the RCA audio connections are on the passenger side of the RZR. Zip-tie
and secure the unused power and speaker harness for the subwoofer amplier if not used.

AMPLIFIER PREPARATION AND MOUNTING (2018.5 Turbo S & 2019+ Models)
Before installing the dual amplier plate with the amplier(s) in position, you must prepare the mounting area
in the vehicle to accept the plate. The amplier plate is installed centered, up high under the dash. Use the
information in this section to determine which installation steps are specic to your vehicle and options.
NOTE - These instructions assume two ampliers and all speakers are present in a Stage 5 System. This
makes upgrading by adding a subwoofer and rear speakers easier. It’ll be prewired for those upgrades.
STEP 1 – DETERMINE YOUR MODEL’S OPTIONS FOR DUAL AMPLIFIER PLATE MOUNTING
Factory-Installed (OEM) Amplier ONLY
• If you have ONLY the OEM installed amplier and are re-using it, you must remove it from the top of the
factory plate and reinstall on the bottom side of the plate to allow clearance for the other amplier plate.
If you are NOT re-using the OEM amplier you can disconnect the amplier and remove the amplier
and mounting plate. You will still reuse (2) 10mm bolts to secure the dual amplier plate with this kit.
Dynamix®ECU ONLY
• If you have ONLY the Dynamix ECU then set the
ECU and ECU mounting bracket back in the original
placement ensuring the wiring intended for the
amplier harness is routed through the gap area at
the forward section of the bracket. Loosely reattach
only the two (2) 10mm rear bolts for the ECU bracket
(nearest the dashboard) as shown in Figure 10-4. *It
is only important the ECU bracket is back in place for
trial tting of the dual amplier plate. It will not have
its nal reassembly at this step.
Factory-Installed (OEM) Amplier AND Dynamix®ECU
• If you have the Dynamix ECU AND the OEM installed amplier and planning on re-using the OEM
amplier, then the OEM amplier will need to be relocated elsewhere to make room for the amplier
plate provided in this kit. If you are NOT re-using the OEM amplier you can disconnect the amplier
and remove it. Loosely reattach only the two (2) 10mm rear bolts for the ECU bracket (nearest the
dashboard) as shown in Figure 10-4. *It is only important the ECU bracket is back in place for trial tting
of the dual amplier plate. It will not have its nal reassembly at this step.
NO Factory-Installed (OEM) Amplier OR Dynamix®ECU
• If you have NO Dynamix ECU or OEM installed amplier, use the (2) T40 screws provided in the MB
Quart RZR Stage 5 kit as shown in Figure 10-5. These screws attach the amplier plate in the two
identied holes as shown in Figure 10-6.

AMPLIFIER PREPARATION AND MOUNTING (2018.5 Turbo S & 2019+ Models Continued)
STEP 2 – AMPLIFIER MOUNTING
Mount the MB Quart amplier(s) on the dual amplier
plate in the conguration shown in Figure 10.7. This
conguration is critical to make sure you can access
your ne-tune adjustments for level, low pass lter (LPF)
and bass boost.
STEP 3 – TRIAL FITTING THE DUAL AMP PLATE
With the amplier(s) mounted to the plate, place it into position as shown in Figure 10-8. Be sure there is
free movement of the wiring harness with enough length to connect to the amplier’s onboard connectors.
• if you have the Dynamix®ECU and/or OEM
amplier bracket - Loosely t the remaining two (2)
10mm bolts to check the t of the dual amp plate.
This is shown in Figure 10-8.
• If NO Dynamix® ECU or OEM amplier bracket
- Use the two (2) T40 screws provided with the MB
Quart Stage 5 kit 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 dual
amp plate will not have its nal reassembly until after the system has completed the steps in the INITIAL
TESTING and FINE TUNING sections.
STEP 4 – REMOVE DUAL AMP PLATE FROM ITS LOCATION AND FLIP OVER
With the ampliers connected to the wiring harness, place a towel or blanket over the open hood area.
• If you have the Dynamix® ECU and/or OEM amplier bracket - Remove the rst two (2) 10mm bolts.
Remove the dual amp plate and ip it over on a towel or blanket to avoid scratching the amplier(s)
heatsink as shown in Figure 10-9. Next, remove the remaining two (2) 10mm bolts from the ECU or
OEM amplier mount (if present) and place the ECU to the side as when initially disassembled on page
8.
• If NO Dynamix® ECU or OEM amplier bracket - Remove the (2) T40 metal screws for the amp plate.
Remove the dual amp plate and ip it over on a towel or blanket to avoid scratching the amplier(s)
heatsink as shown in Figure 10-9.
This step will allow you to continue working on the other
parts of the installation and access other wiring until
you’re ready to power up the system, complete nal
testing and nalize the reassembly.

AMPLIFIER AND SPEAKER WIRING HARNESS CONNECTIONS
With your amplier(s) mounted, subwoofer installed and connected to the mono amplier, you can now
begin laying in the front/rear speaker harnesses and plugging in all the remaining connectors. While you are
working on your system, we recommend covering the ampliers to avoid scratching them or inadvertently
hitting the adjustment dials 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 ampliers
respectively. At the same time, if you have (or will later install) optional illuminated
MB Quart SR1-120RGB LED light rings, connect the red/black wires as well. Next,
connect full range speaker connectors to the two channel amplier. The optional
subwoofer amplier is prewired and can easily be added at a later date with the
MBQR-SUB-2 package. See Figure 12-1 for the connection diagram.
STEP 2 – ROUTE FRONT SPEAKER HARNESS
Make sure your front left and front right kick panel
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.
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
Even if you aren’t currently installing rear
speakers, we recommend routing the rear
speaker harness through the console area as
shown in Figure 12-2. You can zip tie the harness
in an accessible area for later use when you add
rear speakers.
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.

MOUNTING THE KICK PANEL SPEAKERS
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 HOLES USING SUPPLIED TEMPLATE
Use a few small lengths of painter’s tape in the kick panel area to
easily see marks left by a felt-tipped pen or pencil. Place the clear
plastic template on driver’s side as shown in Figure 14-1 and mark
the mounting holes to drill. Repeat on the passenger side.
STEP 2 – DRILL HOLES
Drill (2) 1/2 inch mounting holes into the fender where you
marked the tape shown in Figure 14-2. A 1/2 inch step drill bit is
recommended for this step. Repeat this process and drill two more
1/2 inch mounting holes on the passenger’s side kick panel area.
Remove any tape in the drilling area from the interior kick panels.
STEP 3 - PLACE DRIVER’S SIDE KICK PANEL
Place driver’s side kick panel pod in its location as shown in Figure
14-3. Ensure the positioning lines up with the holes you’ve drilled.

AMPLIFIER SETTINGS
Before preparing the source unit and dash reassembly, make the following adjustments to the setting. See
the INITIAL TESTING and FINE TUNING sections for additional information on nal system adjustments
and personalized settings. The chart below provides general crossover and bass boost switch settings
depending on the RZR tuned package you have.
TUNED PACKAGE TWO-CHANNEL AMPLIFIER MONO AMPLIFIER

MBQR-SUB-2 N/A Bass Boost to 0dB
LPF to 100Hz
This manual assumes the full Stage 5 System and provides the information for initial settings accordingly.
STEP 1 – ADJUST TWO-CHANNEL AMPLIFIER
Looking at the NA2-400.2RC shown in Figure
15.1, make the following initial adjustments:
● LEVEL - Rotate control to slightly past
halfway (about the 1 o’clock position). This
represents an input level that will closely match
the source unit’s output at full volume allowing
the amplier to achieve full power without
notable distortion.
STEP 2 – ADJUST (OPTIONAL) MONO AMPLIFIER - IF PRESENT
Looking at the NA2-400.1 shown in Figure 15.2, make the following initial adjustments:
● BOOST - Switch to “0dB” position.
● LEVEL - Rotate control to halfway (pointing
up). This represents an input level that will
closely match the source unit’s output at full
volume allowing the amplier to achieve full
power without notable distortion.
● LPF - Rotate control to halfway (pointing up).
This is approximately 100HZ.
● SUBSONIC - Leave in the lowest (15Hz
position). If the subwoofer has trouble with
the lowest notes in your choice of music upon
testing, you can adjust up slightly about 1/4 turn.

RIDE COMMAND®ADAPTERS
CONNECT RIDE COMMAND AUDIO ADAPTERS (Ride Command Models Only)
With the Ride Command STAGE Tuned Audio packages, two plug-in audio output adapters are included.
These allow the vehicle’s Ride Command system to easily connect to the system ampliers while retaining
Ride Command’s functionality and features.
STEP 1 – LOCATE AUDIO OUTPUT PLUGS
There are three AMP plugs located behind and on either
side of the Ride Command dash unit as shown in gure
20-1 and 20-2.
Identify the labels on the plugs. You are looking for
“AMP1” and “AMP3” plug labels.
In this installation you will only use “AMP1”, but
“AMP3” plug location is good to know for later
upgrade to the optional subwoofer system.
STEP 2 – CONNECT ADAPTERS
Connect the Ride Command adapter to AMP1 plug as
shown in gure 20-3. Both adapters included in the kit
are identical. Simply choose and connect one.
STEP 3 – CONNECT REMOTE AMP TURN-ON
Route and connect AMP1 blue wire (remote amp turn
on) from the adapter to the blue wire in audio system’s
four-wire source unit harness. Only the blue wire
connects. The three remaining wires are not used in a
Ride Command application. See Figure 20-4.
STEP 4 – CONNECT RCAs TO AMPLIFIERS
Route and connect the RCA audio cables from the
AMP1 adapter to the NA2-400.2RC two-channel full
range amplier. See Figure 20-4.
Note about Ride Command fader operation - Although
the Stage 2 system ONLY includes front speakers,
you can add optional rear speaker pods (part# NHT1-
120BPR) using the pre-wired rear speaker harness,
installing the speaker pods and simply making those
connections as shown on page 15.
When rear speakers are installed in that way, front and
rear speakers in a MB Quart RZR-tuned system are on
the “front” of the Ride Command outputs so there is no
function for the “rear” on the fader once the system is
installed and operating.

MOUNT THE USB & 3.5mm (AUX) DASH ADAPTER (Non-Ride Command)
With the non-Ride Command STAGE Tuned Audio packages, a PSAP-2S dual input waterproof dash
adapter is included. This means that no matter how you store and play your music, you have plenty of
connections.
STEP 1 – MOUNT ADAPTER
Route wires from the PSAP-2S input adapter through the switch opening
in the vehicle-specic panel where the source unit is already mounted.
Press the adapter into place to ensure the snaps lock it in.
STEP 2 – CONNECT TO SOURCE
There is an 18 inch (0.5 meter) cable that extends the USB and AUX
input from your source unit. After mounting the adapter, 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 INITIAL TESTING and FINE TUNING process is complete, zip
tie and secure any excess cable length.
