About: Axxess AXSUB-GM6 Add-on Subwoofer Data Interface for Select 2021-Up GM Vehicles

Axxess provides a simple plug-and-play solution for adding an aftermarket subwoofer to select Chrysler, Ford, and GM vehicles. The patented Add-A-Sub™ interface (AXSUB) restores and extends the low-frequency response that is often limited by factory radios, delivering stronger, more accurate bass so your subwoofer can perform at its full potential. Installed directly at the radio location, the AXSUB kit includes vehicle-specific harnesses and a dash-mountable bass control knob for convenient adjustment.

Features:

  • Designed for non-amplified systems
  • 2-channel non-fading 5V RMS output
  • Fixed low-pass frequency of 234Hz
  • 250mA remote turn-on output
  • Bass knob & vehicle-specific harness included
  • Installation done at the radio location
  • Micro “B” USB updatable
  • 1-year limited warranty

Includes:

  • Interface
  • Vehicle T-harness
  • Bass knob
