Axxess AXDSPX-GL9 DSP Interface With Pre-Wired Harness for GM 2016-2017

The Axxess AX-DSP is an all-in-one solution for a variety of car audio system setups, from fixed level output (digital) to analog OE systems or even the expansion of an OE system with a subwoofer. The Axxess preamplifier solution was developed to give you the option of expanding the factory amplifier or adding a subwoofer without losing sight of the OE features and controls of the radio.

With the Axxess T-wiring harness you can easily connect the AX-DSP to selected vehicles via plug & play.
