HushMat - Trunk Sound-Damping Kit, 19 Sq. Ft - Stealth Black Foil

With 2 pieces of 2mm-thick 10" x 12" butyl-rubber-composite material with an aluminum constraining layer, this Ballistic Hollow Point Series SDHP-SK speaker kit covers up to 1.7 sq. ft. and dampens vibrations to enhance the audio quality in your vehicle.

Reduce both the vibration and the noise that distorts the great sound coming from your car speakers with the USA-made material HushMat Ultra. Which sounds better—a home theater speaker or a car door speaker? Right—the home speaker! That's because it is the enclosure that the speaker sits in. The fine-crafted wooden cabinet is going to sound better than the metal door of a car full of holes. And that's a shame because in most cases, the quality of the speaker going in the car door is better than that in the home! The HushMat speaker kit solves that problem. It creates an anti-vibration gasket between the speaker and the metal door. When the speaker cone moves, the vibration of the speaker will not transfer to the metal door and create distorting vibration. Better sound from HushMat guaranteed! HushMat is the only OEM-specified and -approved sound deadening and thermal insulating material available to the automotive aftermarket. This kit contains 2 sheets of 10 in. x 10 in. Stealth Black Foil for 1.4 sq. ft. of coverage.
