This AXXESS bass knob is an add-on accessory for AXDSP-X. If you are using AXDSP-X to install an aftermarket subwoofer, it provides a quick independent control of the subwoofer gain.
For use with your existing AXDSP-X subwoofer control.
Connect the orange wire on the AXBK-1 to the orange wire of your AXDSP-X 20-pin harness or your existing vehicle-specific harness. Connect the black wire on the AXBK-1 to the chassis ground in the vehicle.
There is a detachable mount so the gain control knob can be mounted under a dash or in a pocket. Also provided are a washer and locking nut so the gain control can be flush-mounted.
