INSTALLATION OPTIONS I N S TA LL ATI O N

Adding a sub to a factory system:

This feature offers the ability to add a subwoofer to a factory system, whether ampliﬁed or nonampliﬁed. (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, whether ampliﬁed † or non-ampliﬁed. (refer to page 4)

For ampliﬁed models the amp must be bypassed/unplugged, and With OE Ampliﬁer chosen in

†

the Conﬁguration tab under Vehicle Type.

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 AX-DSPX-GL1 vehicle T-harness to the vehicle and make all necessary

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

3. Plug the AX-DSPX-GL1 vehicle T-harness to the AX-DSPX-GL1 interface.

4. Plug the AX-DSPX-GL1 interface harness to the AX-DSPX-GL1 interface.

5. Download and install the AXDSP-X 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.

† 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

Setup Instructions

• General information tab for installing the interface.

MOBILE APP

Bluetooth Connection

MOBILE APP (C ONT.)

• 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.

Conﬁguration

MOBILE APP (C ONT.)

• 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 ONT.)

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 ONT.)

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.

MOBILE APP (C ONT.)

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.

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 ONT.)

• Chime Volume - Allows the chime volume 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
