ResoNix Stage-4 2-Door Sound Deadening Kit Specifications
The Complete Car Door (Pair) Sound Deadening Kit: Stage-4
This is the go-to kit for those who want to take their door treatment to the highest levels, a real one-and-done solution. Sitting above our most popular Stage-3 kit, Stage-4 adds additional layers and materials that allow for even greater noise reduction, further improved midbass performance, a potentially time-saving and easier fabrication & installation of block-off plates, and a more refined driving experience overall.
It includes everything found in Stage-3, plus added components to help seal large access holes and further block external noise: ResoNix Mega CLD Squares, original ResoNix CLD Squares, ResoNix Fiber Mat Black Edition, ResoNix Guardian, ResoNix Barrier, ResoNix CCF Strips, ResoNix CCF 3S Tape, ResoNix Butyl Rope, and a ResoNix Roller.
This kit is designed to reduce panel resonance, eliminate rattles and buzzes, absorb airborne noise, block sound through openings in the inner skin, and seal your midbass drivers to the grille or trim. While Stage-4 isn’t always necessary for every vehicle, when your doors allow for this level of treatment, the results are unmatched by anything else available.
