Frequently asked questions

What is Dynamat Xtreme Squared 18 used for?

Dynamat Xtreme Squared 18 is a self-adhesive sound deadening material applied to vehicle panels, doors, floors, and roofs to reduce road noise and vibration. It also improves the acoustic performance of in-car audio systems by deadening the sheet metal panels that speakers are mounted to.

How much coverage does one pack provide?

One pack contains eight sheets of 46cm x 46cm, giving a total coverage of 1.67sqm (18 sq ft). This is suited to treating a door pair, a floor section, or targeted panel areas in a vehicle.

What is the 1-inch cutting grid on the Dynamat Xtreme Squared 18?

Each sheet has a 1-inch grid printed on the surface, allowing the material to be cut to size without needing a ruler or measuring tape. Simply score along the grid lines for a clean cut.

How does Dynamat Xtreme improve speaker sound quality?

Dynamat Xtreme deadens the resonance and vibration of sheet metal panels. When speakers are mounted in deadened door panels, the panel acts as a more solid acoustic baffle, reducing unwanted vibration and improving the speaker's dynamic range and bass response.

How is Dynamat Xtreme Squared 18 installed?

Dynamat Xtreme is self-adhesive. Peel the backing, press firmly onto a clean, dry panel surface, and roll flat with a roller or firm pressure for maximum adhesion. The 1-inch cutting grid allows easy trimming to fit irregular panel shapes.
