INSTALLATION OPTIONS I N S TAL L ATIO N

Adding a sub to a factory system:

This feature offers the ability to add a subwoofer to a factory system. (refer to page 3)

Adding a full-range amp & sub to a factory system:

This feature offers the ability to add a full-range amp and sub to a factory system. (refer to page 4)

16-pin header port:

Inside the interface is a 16-pin header port for adding optional modules (sold separately). Page 5 and 6 will show the installation and use of these modules.

• AXDSPL-BT - Bluetooth streaming interface

• AXDSPL-SP - Toslink digital output

Note: 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.

1. Remove the factory radio †, then unplug all connectors.

2. Install the AXDSPL-VW2 vehicle T-harness to the vehicle and make all necessary

connections, but leave the amp turn-on wire disconnected.

3. Plug the AXDSPL-VW2 vehicle T-harness to the AXDSPL-VW2 interface.

4. Plug the AXDSPL-VW2 interface harness to the AXDSPL-VW2 interface.

Download and install the AX-DSP-X app from the Google Play Store or Apple App Store

Cycle the ignition on.

7. Open the app then select the Bluetooth Connection tab. Follow the instructions to pair the mobile device to the interface. Refer to page 6 for more information.

8. Scroll to the Conﬁguration tab then select the vehicle type. Press the Lock Down ‡ button to save the conﬁguration. Refer to page 7 for more information.

9. Connect the amp turn-on wire.

10. Adjust the settings in the app as desired. Press the Lock Down ‡ button to save any

new conﬁgurations.

† Refer to Metra online for dash disassembly. If Metra makes a dash kit for the vehicle,

disassembly will be within those instructions.

‡ Anytime the interface is locked down the key must be cycled off then back on

BLUETOOTH STREAMING INTERFACE

• The AXDSPL-BT Bluetooth streaming interface can be used to stream media directly to the interface.

• While streaming media the volume on the phone will be used. As an option, the AXBK-1 (sold separately) can be used to control the volume.

AX-DSPL-BT

Note: The bass knob included with the AXDSPL-VW2 can be used if it will not be used

to control a subwoofer.

1. Important! Unplug the interface from the vehicle.

2. Remove (4) Phillips screws securing the interface, then remove the top cover, exposing

the circuit board within.

3. Locate the 16-pin header on the circuit board.

4. Important! Referencing how the AXDSPL-BT is laid out in the picture, carefully line up

the header pins to the interface. Gently press down to secure.

Note: Both interfaces may be damaged if installed wrong.

5. Reinstall the top cover to complete the installation.

AXBK-1 Installation:

6. Connect the Brown wire from the interface to the Orange wire from the AXBK-1. Ground the Black wire from the AXBK-1.

REV. 8/3/2020 INSTAXDSPL-VW2

Bluetooth Connection

MOBILE APP (C ON T.)

• Scan - Press this button to start the Bluetooth pairing process, then select the interface once it is found. “Connected” will appear in the top left corner of the app once paired.

Note: The ignition must be cycled on during this process.

• Disconnect - Disconnects the interface from the app.

Continued on the next page

Conﬁguration

MOBILE APP (C ON T.)

• Identify - Click this button to send a test tone to the front left speaker* * Only installations using the front left output (white RCA jack).

• Reset to Defaults - Resets the interface to factory settings. During the reset process the amp(s) will shut off for 5-10 seconds.

•

Vehicle Type - Select the vehicle type from the drop down box, then click the apply button

• Lock Down - Click this button to save the selected settings.

Attention! This must be done before closing the app or cycling the key otherwise all new

changes will be lost!

•

Save Conﬁguration - Saves the current conﬁguration to the mobile device

• Recall Conﬁguration - Recalls a conﬁguration from the mobile device.

• About - Displays information about the app, vehicle, interface, and mobile device.

• Set Password - Assign a 4-digit password to lock the interface. If no password is desired, use “0000”. This will clear out any currently set password. It is not necessary to lock down the interface when setting a password.

Note: A 4-digit only password must be chosen otherwise the interface will show “password

not valid for this device”.

Outputs

MOBILE APP (C ON T.)

Output Channels

• 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 indicates 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.

Continued on the next page

MOBILE APP (C ON T.)

Crossover Adjust

• Select the desired crossover ﬁlter per channel, low pass, band pass, or high pass.

• Select the desired crossover slope per channel, 12db, 24db, 36db, or 48db.

• Select the desired crossover frequency per channel, 20hz to 20khz. Note: The front and rear channels default to a 100Hz high pass ﬁlter to keep the low frequency

signals out. If a subwoofer is not being installed, change the front and rear crossover points down to 20Hz for a full range signal, or to the lowest frequency the speakers will play down to.

REV. 8/3/2020 INSTAXDSPL-VW2

MOBILE APP (C ON T.)

Equalizer Adjust

• All channels can be adjusted independently within this tab with 15 bands of available equalization. It is best to tune this by using an RTA (Real Time Analyzer).

• The Gain slider on the far left is for the channel selected.

Continued on the next page

Delay Adjust

• Allows a delay of each channel. If a delay is desired, ﬁrst measure the

distance (in inches) from each speaker to the listening position, then enter those values to the corresponding speaker. Add (in inches) to the desired speaker to delay it.

Inputs/Levels

MOBILE APP (C ON T.)

• Chime Volume - Not applicable in this application.

• Clipping Level - Use this feature to protect sensitive speakers like tweeters from being driven past their capabilities. If the output signal of the interface clips the audio will be reduced by 20dB. Turning down the stereo will allow the audio to come back at a normal level. The sensitivity of this feature can be adjusted to the listening preference of the user.

• Amp Turn On

•

Signal Sense - Will turn the amp(s) on when an audio signal is detected, and keep on for 10 seconds after the last signal. This ensures the amp(s) won’t shut off between tracks

• Always On - Will keep the amp(s) on as long as the ignition is cycled on.

• Turn on Delay - Can be used to delay audio output to avoid turn-on pops.

• Subwoofer Input - Select Front + Rear
