Stinger Roadkill Sound Deadening Kit – 2-Pack (4 sq. ft.)

Upgrade your ride's sound system and silence the road with the Stinger Roadkill 2-Pack Sound Deadening Sheets. This compact kit delivers 4 sq. ft. of high-performance, self-adhesive sound insulation — perfect for targeted panel treatment or supplementing a larger installation.

Built with a rugged 6-mil aluminium top layer and an ultra-dense 0.65 lbs/ft² butyl blend, Roadkill delivers the highest damping-to-weight ratio in its class. Whether you're treating doors, roof, floor, boot, or firewall, it drastically reduces vibrations, rattles, and unwanted resonance — giving your speakers a solid foundation for tight bass and clear sound.

Why It Works

Most cars are built with thin metal panels that vibrate and resonate, especially near factory speaker locations. Stinger Roadkill mass-loads these areas, turning them into acoustically inert surfaces that absorb energy rather than amplifying it. The result is better bass, less distortion, cleaner mids and highs, and less cabin noise from road and engine. Even stock speakers can sound remarkable with a little Roadkill behind them.

What's in the Box

The kit contains 2 sheets (each 12" x 24") covering 4 sq. ft. in total. Each sheet features a 0.080" total thickness, a 6-mil aluminium layer, and a weight of 0.65 lbs/ft². Peel adhesion strength is 40.89 lb/in (after 24 hours), and the material operates from -80°F to 300°F.

Perfect For

  • Car audio upgrades
  • Panel resonance reduction
  • Bass speaker mounting locations
  • Reducing road noise in vans, 4WDs, and fleet vehicles
  • DIY soundproofing projects
  • Enhancing vehicle temperature control

Targeted 2-Pack Format

Two sheets covering 4 sq. ft. are ideal for focused treatments or topping up an existing installation.

Temperature and Insulation Benefit

Treated panels gain an insulating layer that assists with moderating interior temperatures in addition to noise reduction.

Everything you need to know

A deep dive into our industry-leading technology and high-performance standards.

What does this kit include?

Two sheets, each 12" x 24", covering 4 sq. ft. in total. Each sheet is 0.080" thick with a 6-mil aluminium top layer and a weight of 0.65 lbs/ft².

Can I use it in a van or 4WD?

Yes. The material is equally effective in cars, vans, 4WDs, and fleet vehicles wherever panel noise or resonance is an issue.

Why do thin factory panels cause audio problems?

Factory metal panels vibrate and resonate, especially at speaker locations. Roadkill mass-loads these surfaces, turning them into acoustically inert panels that support tighter bass and cleaner sound.

Does it also help with temperature control?

Yes. Treating panels with Roadkill adds an insulating layer that assists with moderating interior temperatures.

What temperature extremes can it handle?

The material and adhesive operate from -80°F to 300°F, making them suitable for the full range of temperatures experienced inside vehicle panels.
