PREFACE

The AX-DSP-X can be used with an aftermarket system, OEM system, and also an OEM system that is ampliﬁed with either an analog or digitally controlled (ﬁxed signal) OEM ampliﬁer The AX-DSP-X can also grow as your stereo system grows. Start off by adding a subwoofer to an OEM system, then add on from there. Simply reference the Installation Options page to change the AX-DSP-X to the new system. All 10 channels of the AX-DSP-X can be assigned however needed for the installation at hand. If 10 channels of a subwoofer signal is needed, the AX-DSP-X can do it.

In the following section,

It is highly suggested to use an AX-DSP-X pre-wired harness (sold separately) unless you are installing it with an aftermarket radio. As such, the instructions are written in that manner. Certain connections to the vehicle are unique per vehicle and will require the pre-wired harness to reference to.

The AX-DSP-X provides a 12v 1-amp output to turn on an aftermarket ampliﬁer. If installing multiple ampliﬁers, an SPDT automotive relay will be required if the current exceeds that amount. Use Metra part number E-123 (sold separately) for best results.

If installing the AX-DSP-X behind the radio to install a sub amp, the OEM amp can be retained for mids/highs. If installing the AX-DSP-X at the OEM amp location, the OEM amp must be fully removed.

In most cases the CAN Bus wires need to be connected in order for the AX-DSP-X to communicate with the vehicle to turn on and provide an amp turn-on output.

INSTALLATION OPTIONS I NSTAL L AT ION

Aftermarket radio system:

The AX-DSP-X can be used with an aftermarket radio to improve the overall listening experience for car audio enthusiasts. Installers will connect the RCA inputs from the AX-DSP-X to the outputs from the aftermarket radio; Front, Rear, Sub (sub is optional). When using an aftermarket radio with the AX-DSP-X, General must be chosen for the vehicle type. (refer to page 4)

Adding a subwoofer to an OEM System:

This feature offers the Installer the ability to add an aftermarket subwoofer to an OEM system, whether the OEM system is non-ampliﬁed, or ampliﬁed with an analog or digitally controlled (ﬁxed signal) ampliﬁer. If the vehicle is equipped with noise canceling mics, they must be disabled for this type of system. (refer to page 5)

OEM System without an ampliﬁer:

This option allows the Installer to wire the AX-DSP-X directly to the speaker outputs from the OEM radio for an audio signal (high-level). (refer to page 6)

OEM System with an “analog” ampliﬁer:

This option allows the Installer to tap directly to the output of the OEM radio and feed an audio signal into the AX-DSP-X. This type of installation requires the removal of the factory ampliﬁer, and will provide a full range signal to the input side of the AX-DSP-X. (refer to page 7)

OEM System with a “digitally controlled” ampliﬁer:

Digitally controlled systems function differently than analog systems. They have a ﬁxed level audio signal that is controlled through the vehicle’s CAN bus. In most cases the programming content (audio) provided is just two channels, which can be either front or rear. The other channels are for content like Phone/Bluetooth, SMS reader, SYNC, or OnStar. The AX-DSP-X can retain these OEM features, and also provide a clean audio signal. This type of installation requires the removal of the factory ampliﬁer, and will provide a full range signal to the input side of the AX-DSP-X. (refer to page 7)

Factory Radio Systems

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

2. Install the vehicle speciﬁc T-harness (sold separately) and make all necessary

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

3. Plug the 20-pin AX-DSP-X harness into the AX-DSP-X.

4. Plug the 16-pin AX-DSP-X harness into the AX-DSP-X.

5. Plug all connectors back into the OEM radio.

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

7. Using the app, select the vehicle.

8. Connect the amp turn-on wire from the AX-DSP-X.

9. Test all functions of the installation, then reassemble the dash to complete the

installation.

* Refer to Metra online for dash disassembly. If Metra makes a dash kit for the

vehicle, disassembly will be within the instructions.

Aftermarket Radio Systems

1. Complete all necessary connections to the radio and vehicle, but leave the amp

turn-on wire disconnected.

2. Plug the 20-pin AX-DSP-X harness into the AX-DSP-X.

3. Plug the 16-pin AX-DSP-X harness into the AX-DSP-X.

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

5. Using the app, select the vehicle.

6. Connect the amp turn-on wire from the AX-DSP-X.

7. Test all functions of the installation, then reassemble the dash to complete the

installation.

Conﬁguration

AX-DSP-X APP (CONT.)

• Identify - Click this button to conﬁrm that the AX-DSP-X is connected properly. If so, a chime will be heard from the front left speaker.

• Reset to Defaults - Resets the AX-DSP-X 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

• Without OE Ampliﬁer or With OE Ampliﬁer, then click the apply button

• 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.

Page 11

Conﬁguration (Cont.)

AX-DSP-X APP (CONT.)

• Apply Conﬁguration - Allows a recalled conﬁguration to the AX-DSP-X. The AX-DSP-X will need to be locked down to save the recalled conﬁguration. This process will shut the ampliﬁer off between 5-10 seconds while the conﬁguration is uploaded to the AX-DSP-X.

• About - Displays information about the app, vehicle, AX-DSP-X, and mobile device.

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

AX-DSP-X APP (CONT.)

Output Channels

• Location - Location of speaker.

• Group - Used to join channels together. Example, left front woofer/

midrange and left front tweeter will be considered simply left front to the AX-DSP-X. The letter M denotes 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.

Amp Turn On

• Signal Sense - Will turn the ampliﬁer on when an audio signal

is detected, and keep on for 10 seconds past the last signal. This ensures the ampliﬁer doesn’t shut off between tracks.

• Always On - Will keep the ampliﬁers on as long as they is cycled on.

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

Crossover Adjust

AX-DSP-X APP (CONT.)

• If installing a subwoofer, the front and rear outputs will default to a 100Hz high pass ﬁlter to keep the low frequency signals out of the full range speakers. 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 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

AX-DSP-X APP (CONT.)

• 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

Page 15

Delay Adjust

AX-DSP-X APP (CONT.)

• Allows a delay of each channel, up to 10 milliseconds. First measure the distance (in inches) from each speaker to the listening position, then enter those values. If a delay is desired, add to the desired channel(s), up to 99 inches.

Levels

AX-DSP-X APP (CONT.)

• Clipping Level - Use this feature to protect sensitive speakers like tweeters from being driven past their capabilities. If the output signal of the AX-DSP-X 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.

• Chime Volume - Allows the chime volume to be adjusted up or down.

Note: In newer Ford vehicles chimes will be heard through the gauge

cluster if the OEM ampliﬁer is removed
