PREPARATION FOR INSTALLATION
Before dismantling your vehicle, we suggest you prepare all your components, enclosures, and wiring harnesses. It increases efficiency to have everything ready when each component is installed.

STEP 1 – CONFIRMING POWER TO BUS BAR (Applies to 2013-2018 RZR Models)
The Polaris RZR has a harness that connects the battery under the seat to the bus bar harness located under the hood. The bus bar is typically where aftermarket accessories easily connect.
The harness is shown in Figure 1-2. 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 specific RZR model you own. 2018.5 Turbo S and all 2019+ RZR models already contain a bus bar harness. The bus bar is the recommended location to connect the NA2-400.1 amplifier’s power and ground wiring.

WHAT FITS MY VEHICLE?

TWO RZR-TUNED AUDIO SYSTEM OPTIONS: ENHANCE YOUR SUBWOOFER!

The Stage 2 audio system compliments your MBQR-SUB-2 subwoofer installation perfectly! Depending on whether or not your RZR® vehicle has the optional Ride Command® system, you have two choices. This also provides amplifier mounting plates and a fully integrated wiring harness to make the subwoofer installation seamlessly integrated. The Stage 2 system would be purchased separately.

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-specific Ride Command adapters in this kit to allow easy plug-in interface for connection to the amplifier inputs in the Stage 2 system. Also includes 8” kick panel speakers and a 400-watt amplifier.

Ride Command Adapter

VEHICLES WITHOUT RIDE COMMAND®
If your RZR model is not equipped with the Ride Command system, the MBQRSTG2-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- specific housing that fits in the center dash storage pocket space (once the pocket is removed). Also includes 8” kick panel speakers and a 400-watt amplifier.

SUBWOOFER MOUNTING

SUBWOOFER ENCLOSURE MOUNTING (ALL MODELS)
Prepare to mount the subwoofer into the glove box and grab bar location. 2018.5 Turbo S and 2019 and newer RZR models, use only the rear mounting plate and four 1/2” bolts as shown in Figure 8-1. All other RZR models use both mounting plates and all eight 1/2” bolts as shown in Figure 8-2.

2018.5 Turbo S and 2019+ RZR Models use only rear mounting plate and four 1/2” bolts.

2013-2018 (non-Turbo) RZR Models use both mounting plates and eight 1/2” bolts.

STEP 1 – POSITION SUBWOOFER ENCLOSURE
Sitting on the floor of the RZR, hold the subwoofer enclosure up to the grab bar pipe and push it forward into place as shown in Figure 8-3.

STEP 2 – BEGIN MOUNTING ENCLOSURE
Begin mounting the subwoofer to the RZR using the supplied steel plates and bolts as indicated for your specific year and model. Start by hand-threading the bolts until finger tight as indicated in Figure 8-4, Then, use a 1/2 inch socket with a small ratchet to begin tightening the bolts. 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 amplifier connector.

STEP 3 – 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.
NOTE – When the subwoofer starts to seat into place, continue to push the subwoofer firmly forward as shown in Figure 8-3 as you tighten mounting hardware. This forward pressure will be critical when you reassemble the front dash for fitment into all the clips.
STEP 4 – ROUTE SUBWOOFER WIRING HARNESS
Route the subwoofer enclosure’s wiring harness over to the amplifier area. Connect it to the speaker output of the mono amplifier as shown in figure 8-5 if adding on to a Stage 2 system.

The next section describes connecting to the amplifier.

AMPLIFIER SETTINGS

AMPLIFIER WIRING

If you are connecting the amplifier into an existing Stage 2 system – either
MBQR-STG2-RAD-2 or MBQR-STG2-RC-1, simply plug in the unused power/ground connector of the mono amplifier into the Stage 2 harness. At the same time, if you have (or will later install) optional illuminated MB Quart SR1-120RGB LED light rings for the 8” compression horn front or rear speakers, connect the red/black wires as well. See Figure 9-1 for the connection diagram.

If you are connecting the amplifier on its own – please refer to the electrical connections outlined in the NA2-400.1 installation manual available at MBQuart.com.
It’s recommended that you connect the amplifier’s power and ground wiring at the RZR bus bar location as described on page 3.
Use at least 10 AWG power and ground wire. Be sure to fuse the amplifier’s main power wire with a 30-ampere fuse placed close to the point of connection at the bus bar. Connect the amplifier’s remote turn-on wire to our source unit’s remote turn-on output (typically a blue wire).
Depending on your chosen amplifier location if not using one of the MB Quart vehicle-specific RZR amplifier mounting plates, you may need to extend the wire from the subwoofer to connect with the amplifier.

AMPLIFIER SETTINGS
This manual provides the information for initial settings on the NA2-400.1 subwoofer amplifier accordingly.

STEP 1 – ADJUST MONO AMPLIFIER
Looking at the NA2-400.1 shown in Figure 9.2, 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 amplifier 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.

INITIAL TESTING
This step is to confirm that everything is working before you put the vehicle back together

STEP 1 – RECONNECT THE BATTERY
With the power/ground wiring connected to the bus bar, reconnect the negative terminal of the negative battery cable as indicated in Figure 10-1.
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
Confirm connectivity of the system you just installed.

● AMPLIFIER
Ensure the amplifier’s power connection has the fuse in place.
Ensure the amplifier is properly grounded.We recommend the bus bar location.
Ensure the remote turn-on wire is connected to the source unit.
Ensure the amplifier’s inputs are connected to the source unit’s output(s) properly.
Ensure the amplifier initial settings are completed. Refer to page 11.
● SUBWOOFER
Ensure the subwoofer’s wiring is connected to the amplifier.
If you extended the subwoofer’s wiring because of amplifier placement, ensure the correct polarity is observed – positive amplifier output to positive subwoofer wire and negative amplifier output to negative subwoofer wire.
If the subwoofer is working and producing sound, proceed to the next section – Fine Tuning.

FINE-TUNING

FINE-TUNING
When setting up your amplifiers you will refer to the manual inside each amplifier. However, through hundreds of installations, we have determined the settings shown on page 11 are ideal for MBQR-SUB-2 subwoofer system.
NOTE – Gain control, it is important to adjust each amplifier 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.

B. Level Setting

This is a critical step to insure your amplifier is properly adjusted to match the signal output level of your source unit.
THIS IS NOT A VOLUME CONTROL!
1. If possible, with the source unit off, confirm that the primary volume control is turned down (counterclockwise).
2. Turn on the source unit (CD, or MP3 player). Re-confirm that the volume is turned down. Make sure the source unit controls; balance, fader, bass and treble are all set to center or “0” adjustment. Make sure that the green LED on the end of the amplifier is illuminated.
3. Play a clean musical selection of which you are very familiar. CD is preferred. Do not use radio signals for level setting. Hit play and start turning the volume of the source unit up.
4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until you hear speakers begin to slightly start producing distortion.
5. Increase the amplifier gain (clockwise) until distortion is heard, then back the level down (counter-clockwise) until the distortion is eliminated. Small adjustments may need to be made to balance the levels of multiple amplifiers.

REASSEMBLY

VEHICLE REASSEMBLY
Follow along any wiring you’ve routed and zip-tie to the vehicle to assure it doesn’t come loose during rides. Do not zip-tie your wiring to any heat or moisture sources. Once your wiring is secure, you can begin reassembling all the panels. Here is an important checklist so you do not forget anything:
2013-2018 RZR Models
● TIGHTEN NEGATIVE BATTERY TERMINAL FULLY
● REINSTALL SEATS
● FRONT OF DASH – CHECK ALIGNMENT WHERE THE DASH MEETS THE SUBWOOFER
● ZIP-TIE WIRING WHILE AVOIDING HEAT SOURCES OR MOVING PARTS
● REASSEMBLE TOP OF DASH
● REPLACE HOOD
2018.5 Turbo S and 2019+ RZR Models
● TIGHTEN NEGATIVE BATTERY TERMINAL FULLY
● REINSTALL DYNAMIX® ECU BRACKET (IF PRESENT) – TIGHTEN TWO 10MM BOLTS
