This manual assumes the full Stage 5 System and provides the information for initial settings accordingly.
STEP 1 – ADJUST TWO-CHANNEL AMPLIFIER
Make the following initial adjustments to the
NA2-400.2 shown at right:
● X-OVER - Switch to “HP” position.
● LEVEL - Rotate control to halfway starting at
9V (dial 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.
● HP - Rotate control to halfway from 15 Hz
(pointing up). This is approximately 80HZ.
● LP - Not used in this application (position does not matter).
STEP 2 – ADJUST MONO AMPLIFIER
Make the following initial adjustments to the
NA2-400.1 shown at right:
● BOOST - Switch to “0dB” position.
● LEVEL - Rotate control to 3/4 of the rotation
starting at 9v (dial pointing side to side). This
represents an input level to match the source
unit’s output at full volume allowing the full
power without notable distortion. Note source
unit’s “SUB OUT” level setting on next page
(35dB) to correlate with this recommendation.
● LPF - Rotate control to 1/4 turn starting at 50 Hz (dial pointing diagonal as shown). This is approximately
100Hz. Note that the source unit’s SUB OUT frequency setting on the next page is also set to 100Hz to
correlate with this recommendation.
● SUBSONIC - A subsonic lter protects the subwoofer from over excursion. Rotate control to 1/4 turn
starting at 15Hz (dial pointing diagonal) as shown. This is approximately 31Hz.

INITIAL TESTING
Conrm that everything is working as intended before nal tuning, tting and reassembly.
STEP 1 – RECONNECT THE BATTERY
First, ensure the battery is fully charged. Using a 10mm socket, then
reconnect the negative terminal of the negative battery cable as indicated.
STEP 2 – CONNECT SOURCE UNIT
Connect the electrical plug and two RCA audio cables to the source unit.
The “FRONT” RCA outputs connect to the high frequency (400.2) amplier.
The green “SUB” RCA outputs connect to the low frequency (400.1)
amplier. Temporarily set housing in place, but do not yet attach mounting
screws. This will allow for any corrections of wiring if needed.
STEP 3 – INSERT MAIN FUSE AT BUS BAR
With the source unit connected, place the 70a MAXI fuse in the fuseholder
near the bus bar main harness connection.
STEP 4 – TURN ON IGNITION
Turn the ignition key to the ACC position.
STEP 5 – INITIAL CHECKS
The following instructions are for conrming connectivity and basic
functionality. Refer to the full manual for the GMR-LED source unit to use
features like Bluetooth® pairing, adjusting treble and bass or working with
the EQ. Push the PWR button on the source unit and check the system for
all of the following:
● 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 for source unit and test a Bluetooth®source.
● AM/FM RADIO - Unless you have installed and AM/FM antenna, you will only hear static.
● SPEAKERS - Conrm all speakers play the correct range of frequencies (lows coming from the
subwoofer, mid to high coming from front and rear speakers).
● CORRECT LEFT/RIGHT BALANCE - Make sure you are using the controls on the source unit to conrm
“LEFT” is the left-side channel and “RIGHT” is the right-side channel. There will be no change on the fader
front/rear speakers as all speakers are on the same two-channel (400.2) amplier and “FRONT” output.
●SUB FREQUENCY and LEVEL SETTING - In the settings menu, set the source unit’s SUB OUT (Low
Pass) crossover at 100Hz. Next, set the source unit’s SUB OUT level at 35dB for the initial testing. A level
setting of 35dB will allow the recommended gain control settings on the subwoofer amplier to perform
distortion-free, while also allowing you to ne tune any bass-heavy music by easily reducing the sub level
setting from the source unit.
● AMPLIFIERS - If the speakers are playing, the ampliers are on. Conrm settings are correct if
something doesn’t sound exactly right. CONFIRM ALL SPEAKERS ARE CONNECTED TO THE CORRECT
AMPLIFIER before making any further adjustments. Refer to page 9, 11 and 17 for initial amplier settings
during the amplier plate installation. If everything is working and producing sound, proceed to the next
section - Fine Tuning.

FINE TUNING
After you have conrmed and tested that all components are working, you can ne tune the amplier
settings. Through hundreds of installations we have determined the following settings are ideal for the Can-
Am X3 UTV-Tuned Audio Packages. Reference source unit volume level for these settings is 30-35 with no
boost in bass, treble or EQ settings.
NOTE – Gain control, it is important to adjust each amplier 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.

*AFTERMARKET ROLL CAGES
Although MB Quart front speakers
come pre-installed in the Can-Am
replacement panels, they may
require removal from the panel to
t low-slung aftermarket roll cages
that t close to the hood area.
In these cases where t is tight or
would damage the speaker due to
the roll cage position, remove the
speaker from the panel rst, install
the panel in the vehicle, then
connect and install the speaker
into the panel.
Secure the front speaker panel by reinstalling all the remaining clips and T-30 hardware in the same
locations removed during the disassembly process. Do not forget about reinstalling the additional
hidden push pin under the driver’s side dash, between the steering wheel and console, just forward of
the tubular chassis support.

Place the source unit’s housing in the nal center dash installation location with wiring neatly secured
and zip tied in place. Attach the four included T-25 Torx screws through the housing’s mounting holes
into each of the four locations drilled out earlier. Two T-25 32mm screws in the front of the housing and
the shorter two T-25 24mm screws in back.
7
Reinstall four T-30 screws in the center dash. Two forward of the gear selector and two additional
in the upper center dash forward of the fuse panel. Once complete, reinstall the upper center dash
access cover behind source unit housing. Refer to page 4 for disassembly steps and simply do these
in reverse.
8
Reinstall lower center console cover with two T-30 screws and two push pins. Refer to the top of page
6 for disassembly steps and simply do these in reverse.
