Bass that rattles your trunk lid instead of hitting your chest is wasted output, and sound deadener helps you get it back. Sundown Audio offers a 90 mil mat in a 36 square foot pack plus its Premium line in 80 mil and 190 mil thicknesses for doors, floors, trunks and roofs.
Car Audio Bargain is an authorized Sundown Audio dealer shipping from Newton, North Carolina.
Thin sheet metal panels vibrate when a subwoofer or door speaker moves air, and that vibration shows up as buzzes, rattles and a muddy low end. A dense deadening mat bonded to the panel adds mass and damping so the metal stops ringing. The payoff is twofold: less road and exhaust noise reaching the cabin, and more of your system's output heard as music rather than noise.
Thinner mat, such as the 80 mil Premium version, conforms easily around curves and door bracing, which makes it a sensible choice for doors and roof skins where weight and fit matter. The 90 mil SA-9036 pack gives you 36 square feet, enough to treat a trunk or several door panels. The 190 mil Premium sheet adds considerably more mass for trunk lids, rear decks and floors near high-output subwoofers.
For vibration control you do not need wall-to-wall coverage; treating the center of large flat panels does most of the work. Full coverage makes more sense when you are also trying to block road noise. Wipe each panel clean of dust and oil, press the mat down firmly with a roller so it bonds without air pockets, and work in a warm area so it stays pliable.
Most builders begin with the trunk lid, license plate area and rear deck in a sedan, or the rear hatch and quarter panels in an SUV, since that is where subwoofer energy hits first. Doors come next if you run component speakers. Pair sound deadener with subwoofers in a solid enclosure, and wire the system in the right gauge with amp wiring kits or 4 AWG power wire.
