The Stinger RKXSK Roadkill Expert Series speaker kit supplies sound damping material for vehicle doors and speaker mounting areas. The kit includes two 10 x 9 inch adhesive-backed sheets designed to reduce panel vibration and improve speaker performance.

Constructed for installation on door skins and speaker buckets, the sheets use a damping layer with a foil facing to control resonant noise and tighten low-frequency response. The material is trim-to-fit for universal door applications and enhances speaker output by reducing enclosure vibration.
