Adding a subwoofer to a factory system:
The diagram on Page 3 shows the connections that need to be made to add a subwoofer to the
factory system.
Note: RCA jacks sold separately.)
Adding a full-range of amps & subwoofer to a factory system:
The diagram on Page 4 shows the connections that need to be made to add: Subwoofer (RCA jacks
sold separately)
Amplifier (SPDT relay E-123 required) or
Additional Amp (RCA jacks sold separately).
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. Disassemble the dash, unplug all connectors, and then remove the factory radio. †
2. Install the AX-DSPX-MI1 vehicle T-harness to the vehicle and make all necessary
connections, but leave the amp turn-on wire disconnected.
3. Plug the AX-DSPX-MI1 vehicle T-harness to the AX-DSPX-MI1 interface.
4. Plug the AX-DSPX-MI1 interface harness to the AX-DSPX-MI1 interface.
5. Download and install the AX-DSP-XL app from the Google Play Store or Apple App Store.
6. 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.
7. 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.
8. Connect the amp turn-on wire.
9. Adjust the settings in the app as desired. Press the Lock Down ‡ button to save any
new configurations.
† For dash disassembly instructions, refer to metraonline.com. Enter the year, make,
and model of the vehicle in the Vehicle Fit Guide and find instructions under Metra
Radio Install kits.
‡ Anytime the interface is locked down the key must be cycled off then back on.

MOBILE APP (CONT.)
Configuration
IDENTIFY: Click this button to confirm that the interface is connected properly. If it is, a chime will
be heard from the front left speaker.*
* Only installations where the interface is connected to a front left speaker.
RESET TO DEFAULTS: Resets the interface to factory settings. During the reset process the
amplifiers will shut off for 5-10 seconds.
VEHICLE TYPE: Select the vehicle type from the drop down box, select EITHER
EQUALIZER (EQ) TYPE: User has the option of optimizing the car’s sound quality with a Graphic
or Parametric equalizer.
LOCK DOWN: Click this button to save the selected settings.
Attention! This button must be selected before closing the app or cycling the key; otherwise, all
settings 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
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
• If installing a subwoofer, the front and rear outputs will 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.
• Selecting High Pass and Low Pass will provide one crossover frequency adjustment. Selecting
Band Pass will provide two crossover frequency adjustments, one for low pass, and one for
high pass.

Equalizer Adjust
Graphic EQ
• All channels can be adjusted independently within this tab with 31 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.

Parametric EQ
Each output has a 5 Band parametric EQ per channel. Each band will give the user the ability to adjust:
Q Factor
Frequency
Gain
The FLAT button above Filter #1 will reset all curves back to flat.

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 chime volume to be adjusted up or down.
Note: Chimes will be heard through the vehicle’s front left speaker.
• 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.
