Ballistic SSSK Sound Dampening Kit 2 Sets 4 Speakers 10x10in

SKU CH-9QAN-SV7R4

Two sets of 10 by 10 inch elastomeric butyl and aluminum sheets damp vibration for four speakers across a -54 to 149 Celsius range

  • Product typeInstallation Tools
  • Elastomeric butyl and aluminum layer damps vibration and road noise
  • Withstands -65 °F to 300 °F (-54 °C to 149 °C) for reliable adhesion in extreme climates
  • Four 10 × 10 in (254 × 254 mm) sheets cover all four speakers
  • Strong adhesive fuses to sheet metal without extra fasteners
  • Creates an acoustical barrier for clearer in-cabin sound

Two sets for four doors

The kit ships as two identical packs, each containing two 10-inch square sheets. Together they cover four speaker locations, giving a complete door treatment in one purchase.

Elastomeric butyl with aluminum layer

Each sheet is a layered vibration dampener that fuses to metal panels. The adhesive holds from minus 65 degrees Fahrenheit to 300 degrees Fahrenheit, or minus 54 to 149 Celsius, so it survives extreme cabin temperatures.

Installers sealing front and rear doors

Suited for anyone fitting a full four-door system who wants a single box that finishes the job. Not for buyers who only need a single pair of sheets or who are treating panels larger than the 254-millimetre squares supplied.

Questions about this item

What does the 10" x 10" size mean for fitting inside my door panels?

Each sheet measures 254 mm square, covering a typical mid-range speaker cutout; two sheets per set treat the front and rear of one speaker, so the kit handles four speakers total.

How does the elastomeric butyl and aluminum layer affect road-noise reduction?

The butyl damps panel resonance while the aluminum skin reflects heat; together they create a barrier that lowers vibration transfer into the cabin across the full -54 °C to 149 °C operating range.

What surface preparation does the adhesive need to bond reliably?

Clean the metal with a degreaser, ensure it is dry and above freezing, then press the sheet firmly; the adhesive is rated from -65 °F to 300 °F so it holds once cured.
