DEI Boom Mat XL Damping Material - 12.5in x 24in x 4mm - 20.8 sq ft - 15 Pack

If you're looking to quiet down your ride, DEI's Boom Mat XL damping material is a solid option. This material is designed to stick to interior panels like floors, door skins, trunks, and even overhead surfaces, trapping vibrations and reducing the noise that makes its way into the cabin. It's a popular choice among custom car builders for its effectiveness in creating a more comfortable and quieter interior environment.

The Boom Mat XL uses a thick, 4-mil aluminum top skin combined with an asphalt-free, pure butyl noise-constraining layer. This construction effectively stops panels from vibrating and generating unwanted noise. Because it's so efficient, you typically only need to cover 25-50% of a surface to get significant results, which saves on material and installation time. It also performs well in extreme temperatures and features an easy-to-peel plastic liner, making installation straightforward.

This material is great for improving your car's stereo performance by reducing background noise. It's meant to be used as a first layer to control noise and dampen vibrations, setting a good foundation for further sound treatment if desired.
