MESA Mat is the sound damping material we use at Audio Express Inc in Longview, Washington when we're treating door panels, floors, and trunk areas for customers who want a quieter cabin. Sound damping makes a real difference in how a vehicle sounds and feels, reducing road noise and panel resonance that competes with your audio system. MESA Mat is a product we stand behind because we've seen the results firsthand in hundreds of installs. If you're investing in a quality speaker or audio system, treating the vehicle's surfaces first is often the step that makes everything else sound better.
