INSTALLATION OPTIONS INSTALLATION Adding a sub to a factory system: 1. Remove the factory radio †, then unplug all connectors. This feature offers the ability to add a subwoofer to a factory system, whether amplified or nonamplified. (refer to page 3) 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. Adding a full-range amp & sub to a factory system: 3.

MOBILE APP Setup Instructions • General information tab for installing the interface. Continued on the next page REV.
PAGE 6
MOBILE APP (CONT.) Bluetooth Connection • 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. • Disconnect - Disconnects the interface from the app. Note: The ignition must be cycled on during this process.
PAGE 7
MOBILE APP (CONT.) Configuration • 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.
PAGE 8
MOBILE APP (CONT.) Outputs Output Channels 8 • Location - Location of speaker. • Invert - Will invert the phase of the 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. • Mute - Will mute desired channel(s) for tuning individual channels.
PAGE 9
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.
PAGE 10
MOBILE APP (CONT.) 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.
PAGE 11
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. Continued on the next page REV.
PAGE 12
MOBILE APP (CONT.) Inputs/Levels • 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.

MOBILE APP (CONT.) Locking Down Data Last and the most important. You must lock down your configuration and cycle the key!!! REV.
