Installation Video

Designed and manufactured in-house by Trail Grid Pro, this mount allows you to install a bass knob directly into a factory square switch location for a clean, OEM-style finish.

Instead of drilling holes or using adhesive mounts, this blank switch mount lets you integrate your bass knob seamlessly into the dash using a Square Style switch opening. This keeps your installation secure, accessible, and visually factory-correct while preserving the clean look of your interior.

This mount is specifically designed for use with the AudX bass knob included with Trail Grid Pro Kicker and Alpine amplifier kits. For proper installation, the outer housing of the bass knob must be removed so the knob can be mounted correctly inside the switch blank. Once installed, the result is a professional, factory-style appearance with easy access to bass control.

Built for durability and precision fitment, this mount is ideal for custom and professional audio installations where clean design matters just as much as performance. Whether you’re dialing in subwoofer output on the trail or fine-tuning bass on the highway, your bass control stays exactly where you want it.

Proudly made in-house at Trail Grid Pro, this mount reflects the same attention to detail and quality that goes into every product we design.
