Enhance your factory audio system with deeper, more powerful bass using the Axxess AXSUB-CH4 Add-A-Sub Data Interface. Designed for select 2013-2018 Chrysler, Dodge, Jeep, and Ram vehicles with amplified factory audio systems, this vehicle-specific interface provides a clean solution for adding an aftermarket subwoofer and amplifier while retaining the factory radio and existing vehicle functions.
The AXSUB-CH4 utilizes Axxess Add-A-Sub™ technology to provide a dedicated low-frequency output from the factory audio system. It features a 2-channel non-fading 5V RMS output with a fixed 234Hz low-pass crossover, delivering a clean and optimized bass signal for an aftermarket subwoofer amplifier while maintaining proper integration with the factory sound system.
Designed for a professional installation, the AXSUB-CH4 connects at the radio location using the included vehicle-specific T-harness, allowing for a cleaner installation without cutting or modifying factory wiring. The included dash-mountable bass control knob provides convenient adjustment of subwoofer output levels from the driver’s seat.
The interface also provides a 250mA remote turn-on output for activating an aftermarket amplifier and includes Micro-B USB update capability for future firmware updates and expanded compatibility with supported applications.
Before purchasing, vehicle compatibility should always be verified. The AXSUB-CH4 is designed for select 2013-2018 Chrysler, Dodge, Jeep, and Ram vehicles equipped with compatible amplified factory audio systems.
