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

• 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.
Note: The bass knob included with the AXDSPL-HK4 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:

Configuration
• Identify - Click this button to send a test tone to the front left speaker .
• 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 ignition off otherwise all
new changes will be lost!

• 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”.

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.

MOBILE APP (CONT.)
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.

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.

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
Continued on the next page
• Chime Volume - Allows the BlueLink/UVO voice prompts to be adjusted up or down.
• 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
