Frequently Asked Questions - AXDSPL-GM30 AXESS
How do I install the AXDSPL-GM30 in my GM vehicle?
Disconnect the negative battery terminal. Connect the included T-harness between the factory radio and vehicle harness. Plug the DSP into the T-harness. Secure the DSP with screws or double-sided tape. Reconnect battery and power on.
Is the AXDSPL-GM30 compatible with my car?
It is designed for select GM vehicles with factory radios. Check the compatibility list on the AXESS website or contact support for your specific make and model.
How do I adjust the audio settings?
Use the AX-DSP mobile app (iOS/Android) via Bluetooth. The app allows you to adjust equalizer, crossover, time alignment, input gain, and more.
Can I use the DSP with an aftermarket amplifier?
Yes, the RCA outputs can connect to aftermarket amplifiers. Ensure the amplifier's input sensitivity matches the DSP's output voltage (up to 5V).
What does the time alignment feature do?
Time alignment delays each speaker channel so that sound waves from all speakers reach the listener at the same time, creating a better soundstage. Adjust in the app per channel.
How do I reset the DSP to factory defaults?
Press and hold the reset button (small pinhole) on the unit for 5 seconds using a paperclip. All settings will revert to default.
Why is there no sound after installation?
Check that the DSP is powered (LED should be on). Verify the T-harness connections. Ensure the radio is turned on. In the app, check that the master volume is not muted and input source is selected.
Can I update the firmware?
Yes, firmware updates are available via the AX-DSP app. Connect to the DSP via Bluetooth and follow the update instructions. Ensure the vehicle battery is stable during update.
What is the warranty period?
The AXDSPL-GM30 comes with a 1-year limited warranty from the date of purchase. Keep your receipt for service claims.
How do I clean and maintain the DSP?
