The Essential Car Door (Pair) Sound Deadening Kit: Stage-2

This is our best bang-for-your-buck option for sound deadening your car doors, whether you're aiming to improve your sound system’s performance or reduce road noise while driving. It offers excellent performance at a more budget-conscious price point.

The kit includes ResoNix CLD Squares, your choice of ResoNix Fiber Mat in 1.0″ or 0.5″ thickness, ResoNix CCF Strips, ResoNix Butyl Rope, and a ResoNix Roller. These materials work together to reduce resonance, eliminate rattles and buzzes, absorb external noise, and seal your door-mounted midbass speakers to the grille or trim.

While it doesn’t include the full range of materials found in our Stage-3 and 4 kits, it still provides a high level of performance that’s more than enough for most systems. It’s a great option if you want serious results without stepping into the more advanced treatments found in our higher stages.
