You've installed speakers and subwoofers so you can hear clear, vibrant music in your car. Why put up through road noise? The Dynamat 10425 Xtreme Wedge Pack minimizes your car's irritating resonances and screens out noise from the wind, your engine, and surrounding traffic, all factors that can jeopardize sound quality.
Dynamat designed this self adhesive Xtreme sheet for general use on rear decks, doors, floors, and trunks. Apply this sheet to a car door before mounting a speaker, and you'll transform flimsy metal into a solid, non resonant baffle. Unlike Dynamat original, you can also install Xtreme on trunk lids, roofs, quarter panels, and even under your car's hood. And Xtreme proves four times more effective than original in reducing noise, so you'll hear your music and nothing else.
One 32 x 18" sheet, 0.075" thick, 4 square FT total.
