Axxess Integrate AXSUB-GM5 Subwoofer CANbus Interface with Bass Knob — For Select GM 2021 and Up Vehicles

Add fuller, punchy bass to compatible GM systems with the Axxess Integrate AXSUB-GM5. It provides a 2-channel non-fading 5V RMS output for robust low-frequency signal delivery and includes a dedicated bass knob for on-the-fly level adjustment. Built specifically for non-amplified GM vehicles, the module connects via a vehicle-specific T-harness for straightforward installation at the radio location. A 250mA remote turn-on output handles switching for connected components, and the unit’s firmware can be updated through a Micro "B" USB port to maintain long-term compatibility.
