Axxess AXSUB-GM2 Add-A-Sub Data Interface for Select GM Vehicles
Enhance your factory audio system with deeper, cleaner bass using the Axxess AXSUB-GM2 Add-A-Sub Data Interface. Designed for select 2010-2013 GM vehicles with non-amplified factory audio systems, this vehicle-specific interface provides a simple plug-and-play solution for adding an aftermarket subwoofer and amplifier while retaining the factory radio and its original functionality.
The AXSUB-GM2 utilizes Axxess Add-A-Sub™ technology to provide a dedicated low-frequency signal without replacing the factory stereo. It features a 2-channel non-fading 5V RMS output with a fixed 234Hz low-pass crossover, delivering an optimized bass signal for an aftermarket subwoofer amplifier while preserving the performance of the factory speakers.
Installation is quick and straightforward with the included vehicle-specific T-harness, allowing the interface to connect directly at the radio location without cutting or modifying factory wiring. A dash-mountable bass level control knob is included, making it easy to adjust subwoofer output from the driver's seat for different music styles and listening preferences.
The AXSUB-GM2 also features a 250mA remote turn-on output to activate an aftermarket amplifier and includes Micro-B USB update capability for future firmware updates and expanded compatibility with supported vehicles.
Before purchasing, vehicle compatibility should always be verified. The AXSUB-GM2 is designed for select 2010-2013 Chevrolet, GMC, Buick, Cadillac, and GMC trucks and SUVs equipped with compatible non-amplified factory audio systems.
Whether you're adding a powered subwoofer, improving factory bass response, or building a custom sound system, the Axxess AXSUB-GM2 provides a clean, reliable, and professional solution for integrating aftermarket bass while retaining the factory radio.
