Once the doors were done, it was time to focus on the floor. The floor in these vehicles is pretty stiff, thanks to the awesome chassis, but all metal is resonant.
I plan on using the Resonix Barrier to build covers for the front kick panel openings as that is a source of tire noise. I will stuff Fibermat inside those cavities as well.
I lifted the wiring channels up off the floor to gain access, a bungee cord worked well.
I even foamed under the Styrofoam blocking to prevent any squeaking. The Resonix CCF is awesome to work with.
With the floors treated, the cabin is much less resonant.
This process will continue throughout the rear of the vehicle.
