Polyester fiber mat insulation:

Many vehicle manufacturers neglect adequate insulation of sheet metal parts, engine mounts, trim panels, and other components.

This reduces the sound reproduction of aftermarket speakers due to their vibrations and resonances.

Furthermore, rearward sound reflections from the speakers distort the sound.

Sufficient insulation and damping optimize bass response according to the speaker quality, while also improving midrange reproduction and soundstage.

Decoupling and contact damping of trim panels prevents the generation of unwanted noise. Vehicle acoustics are improved, and road noise is reduced. Polyester fiber mat insulation is used for airborne sound insulation, decoupling of trim panels, and damping of midrange speaker enclosures . 

Note: Clean contact surfaces for bonding to be free of grease and dust using suitable agents. Not suitable for use on the outer door panel. Water-resistant, absorbs water.
