PREFACE
The MPS-DSPL-BT is designed for UTV, Marine and Motorcycle applications when a source is not required. The interface includes the AXDSPL-BT Bluetooth Streaming circuit board. This
board plugs directly into the DSP’s circuit board and will allow your phone or tablet to stream music directly to your aftermarket amplifiers. The MPS-DSP-BT is housed in a water tight
case making it perfect for ON/OFF road vehicles that are exposed to the elements. We recommend matching the MPS-DSPL-BT with our MPS-RZKIT for 2014-2020 Polaris RZR.
The MPS-DSPL-BT provides 6 outputs that are assignable to match your systems requirements. Outputs are commonly assigned as Front, Rear, and Subwoofer, which are all setup
through the free Axxess AX-DSP-XL application. Included with interface are two separate knobs that are used as an overall system volume control and a subwoofer’s volume control.
The interface provides a 12-volt 1-amp output to turn on aftermarket amp(s). If installing multiple amps, an SPDT automotive relay will be required if the amp turn-on current of all
amps combined exceeds 1-amp. Use Metra part number E-123 (sold separately) for best results.

• The AXDSPL-BT Bluetooth interface will be used for adding a Bluetooth interface to the
MPS-DPSL-BT for playing music from your smart device.
• While playing music the volume can be controlled from your streaming device or from
the included volume knob.
1. Important! Make sure the 16 pin and 20 pin plugs are disconnected from the
circuit board before installing the ASDSPL-BT.
2. Locate the 16-pin header on the circuit board.
3. Important! Referencing how the Bluetooth interface is laid out in the picture,
carefully line up the header pins to the AXDSPL-BT Bluetooth interface. Gently
press down to secure.
Volume Knob Installation:
• Connect the Brown wire (Volume Control Wire) from the MPS-DPSL-BT harness, to the
Orange wire from the volume knob you want controlling the overall volume of your
system. The black wire from your volume control will need to be grounded. Tapping
into the ground wire from the MPS-DSPL-BT harness is recommended.
Subwoofer Knob installation
• Connect the Orange wire from the MPS-DSPL-BT harness, to the Orange wire from
the bass knob. The black wire from your volume control will need to be grounded.
Tapping into the ground wire from the MPS-DSPL-BT harness is recommended.

1. Install the MPS-DPSL-BT harness and make all necessary connections but leave the
amp turn-on wire disconnected.
2. With the arrow stamped onto the cap facing upwards, push the 16-pin connector from
the MPS-DPSL-BT harness harness into the left side of the cap. The locking clip on the
connector should face upward. Make sure the gasket is seating properly in the cap.
(Figure A)
3. With the arrow stamped onto the cap still facing upwards, push the 20-pin connector
from the MPS-DPSL-BT harness into the right side of the cap. The locking clip on the
connector should face upward. Make sure the gasket is seating properly in the cap.
(Figure A)
4. Plug the 16-pin and 20-pin connectors from the MPS-DPSL-BT harness into the
circuit board. (Figure A)
5. Slide the assembly into the case, then click it shut. Zip-tie the enclosure to a secure
location. Make sure the harnesses are pointing down to ensure that no outside
elements can enter the enclosure.

From the configurations page you should first test
your system to make sure everything is connected
properly after the DSP. To test your setup select the
IDENTIFY button. This will play a chime thought
your setup to confirm your system is ready to pass
audio. (Figure 1)
Next select your VEHICLE TYPE (Figure 1)
The MPS-DSPL-BT interface will be using the
Bluetooth circuit board as the source select General
under the “Select Vehicle Type and OE Amp
Options” menu. Keep “Without OE Amp” selected.
Then select Apply. (Figure 2)

Next Select the OUTPUTS tab – This screen is where you setup your speaker’s output channels. Under the GROUP menu, select the first drop down arrow to the right of the word NONE.
Select the name from the dropdown menu that matches the location listed on the far left of the screen.
Example: #1 – Location - Left Front, under the Groups dropdown menu select Left Front. (Figure 3)
• Location - Location of speaker.
• Group - Used to join channels together for simple equalization. Example: left front woofer/midrange and left front tweeter will be considered simply left front.
The letter M denotes the speaker assigned as the master speaker.
• Invert - Will invert the phase of the speaker.
• Mute - Will mute desired channel(s) for tuning individual channels.

Next Screen will allow you to set your crossover points, filter type, and slope. If you would
like to pass full frequency range to your amps set all filters to High Pass and drag the slider
all the way to the left making sure the entire frequency bar is green. (Figure 4)
• Selecting High Pass and Low Pass will provide one crossover frequency adjustment.
Band Pass should only be chosen if installing just front speakers, with one dedicated
amp for the woofers/mids, a second dedicated amp for the tweeters, along with a
subwoofer.
• If you have a specific frequency you would like, select the number above the slider
and enter in your exact frequency.
• Select the desired crossover slope, 24db, 36db, or 48 db. Higher is steeper.
