Axxess Integrate AXSUB-GM6 — Subwoofer CANbus Interface with Volume Control for Select GM 2021 and Up Vehicles

Add deep, controlled bass to compatible GM radios with the Axxess Integrate AXSUB-GM6. Engineered for non-amplified GM systems, it provides a 2-channel non-fading 5V RMS output to drive a subwoofer with consistent low-end performance. A user-accessible bass knob is included for on-the-fly level adjustments, while a vehicle-specific T-harness makes installation at the radio location straightforward. The module offers a 250mA remote turn-on output for system triggering and uses the vehicle CANbus for integration. Firmware can be updated via Micro "B" USB to maintain long-term compatibility.
