ResoNix Stage-2 Car Trunk Sound Deadening Kit

The Essential Trunk Sound Deadening Kit: Stage-2

This is the perfect starting point for sound treating your vehicle's trunk area, whether you're looking to reduce road noise, eliminate rattles, or improve your system’s low-end clarity and impact. Designed for performance without excess, this kit gives you serious results without going overboard.

It includes 10 square feet of ResoNix CLD Squares, one sheet of ResoNix Fiber Mat in your choice of 0.5″ or 1.0″ thickness, and one roll of ResoNix Butyl Rope. These components are selected to target the most critical parts of the trunk area, your trunk lid (or hatch) and interior quarter panels. Whether you drive a sedan, wagon, SUV, or crossover, this kit is optimized to treat those high-vibration, noise-prone sections.

While it’s not as comprehensive as our higher stage kits, this Stage-2 setup is more than enough for many daily drivers and sound system builds. If you’re new to proper sound treatment or want to upgrade without diving all the way into advanced multi-layer kits, this is a smart way to start.

Kit Includes:

• 10 Square Feet of ResoNix CLD Squares with a free Roller

• 1 Sheet of ResoNix Fiber Mat 0.5″ OR 1.0″

• 1 Roll of ResoNix Butyl Rope

We are offering a special on this kit at 10% off the price of purchasing these items individually.

Note: Please ensure your trunk lid and quarter panel areas have enough room for the thickness of Fiber Mat 1.0″. If not, choose the 0.5″ option. If you’re unsure, feel free to reach out for help.
