RoadKill Ultimate combines the benefits of our Expert aluminum/butyl material and Overkill acoustic foam to create the Ultimate noise killer. The combination of these two products will more than double the results than when used on their own.

Reduce a massive amount of unwanted resonating noise (panel vibrations, road noise, exhaust, engine noise & vibration) allowing your audio system to sound even louder and with more clarity and definition.

Our new line of noise and vibration damping material, RoadKill Ultimate, combines the benefits of Stinger’s line of Expert aluminium/butyl material and Overkill acoustic foam.

With the RKU8, we’ve removed a step that many audio installers are currently taking applying two different materials on top of each other for added insulation and noise damping. Not only are audio builds sounding better, but they’re also being completed more efficiently with outstanding audio definition. RoadKill Ultimate is the best solution to reduce a massive amount of unwanted resonating noise including but not limited to: panel vibrations, road noise, exhaust, engine noise & vibration; all of which degrade audio quality. Having a build designed and installed with RoadKill Ultimate allows the audio system to sound even louder and with more clarity and definition.
