Clean up your interior and mount your bass knob the right way with the Trail Grid Pro Tall Bass Knob Switch Blank Mount. Designed and manufactured in-house by Trail Grid Pro, this mount allows you to install a bass knob cleanly into a factory switch location for a truly OEM-style finish.

*Bass knob shown for installation reference only to demonstrate how the mount looks once installed. Bass knob sold separately.
Instead of drilling holes or using adhesive mounts, this blank switch mount lets you integrate your bass knob directly into the dash using a Small Style switch opening, keeping your setup secure, accessible, and visually seamless. It’s the perfect solution for anyone looking to maintain a factory look while upgrading their audio system.
This mount is specifically designed for use with the AudX bass knob included with our 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 clean, factory-style appearance with easy access to bass control.
Built for durability and precision fitment, this mount is ideal for custom audio installs where clean design matters just as much as performance. Whether you’re dialing in your subwoofer level on the trail or cruising 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.
