Metra Ballistic SSSK Speaker Kit

The Metra Ballistic SSSK kit supplies two 10 by 10 inch butyl and aluminium damping sheets. The elastomeric material bonds to sheet metal to reduce panel vibration and road noise. Adhesive performance is rated from minus 65 degrees Fahrenheit to 300 degrees Fahrenheit. Each piece measures 254 by 254 millimetres.

Suits owners upgrading door or deck speakers

Installers who want a quick acoustic barrier behind a speaker pair will find the pre-cut squares convenient. The kit only contains two pieces, so vehicles needing coverage across four doors or larger floor areas will require additional material. Buyers seeking a full-vehicle sound-deadening package should look elsewhere.

Two 254 millimetre square sheets per pack

The pack provides exactly two pieces sized at 254 millimetres by 254 millimetres. This fixed quantity and dimension determine whether the kit covers the intended speaker locations. Verify the mounting area before purchase.

Questions about this item

Will the 10x10 inch sheets bond securely to the existing metal door panels in my car?

The butyl and aluminum layers use a super strong adhesive rated for -65°F to 300°F, so they fuse firmly to sheet metal through seasonal temperature swings.

How can I confirm the SSSK kit is reducing panel vibration after I install it?

Tap the treated door panel; a dull thud instead of a metallic ring shows the dampener is absorbing resonance as intended.

Does the speaker kit include a roller or separate adhesive, or just the two 254 mm squares?

The box contains two 10x10 inch self-adhesive sheets; no extra glue, roller or tools are included.
