1. Locate the factory amp in the passenger side kick panel. Unplug and remove the amp.
2. Install the AX-DSPX-HN3 harness to the vehicle and make all necessary connections, but
leave the amp turn-on wire disconnected.
3. Connect the AX-DSPX-HN3 harness to the AX-DSPX-HN3 interface.
4. Connect the AX-DSPX-HN3 interface harness to the AX-DSPX-HN3 interface.
5. Download and install the AXDSP-X app from the Google Play Store or Apple App Store.
6. Cycle the key 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 5 for more information. (Figure A)
8. Scroll to the Configuration tab then select the vehicle type. Press the Lock Down ‡ button to
save the configuration. Refer to page 6 for more information. (Figure B)
9. Connect the amp turn-on wire.
10. Click the Identify button to confirm the interface is connected properly. A chime will be heard
from the front left speaker. Test all functions of the installation for proper operation.
Note: The outputs may need to be configured within the Outputs tab.
11. Adjust the settings in the app as desired. Press the Lock Down ‡ button to save any new
configurations.
‡ 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.

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

• 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.

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
• 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.

MOBILE APP (CONT.)
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 - 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 Subwoofer
