DYNAMAT SUBWOOFER TRUNK KIT This is a heavy, composite, Butyl/Aluminium, high-temperature, self-adhesive sheet that will dampen, reinforce and stabilise your vehicle's panels to reduce vibration and road noise and allow clearer, louder bass from you car's audio system. Just cut to size, peel-off the backing and stick it on. It is flexible, easy to cut and mould sheets which conform to curves and bond easily to sheet metal and other hard surfaces. Suitable for use in temperatures between -10°C to +60°C (14°F to+140°F). Material can withstand temperature extremes between -54°C to +149°C (-65°F to +300°F) and is highly resistant to ageing. Pack contains Five Sheets, 4sq.ft. each (0.37 sq. mtrs). Total 1.85 sq.mtrs (20sq.ft). Weight 4.8Kg. DYNAMAT SUBWOOFER TRUNK KIT #DYN19405 Acoustic Properties: The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-bourne sound by stating how much vibrational energy (in steel sheets for instance) is converted to heat rather than sound. For constructions containing several layers of damping material, the combined loss factor "n comb" is used. The theoretical maximum loss factor is 1 (no vibration). An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynamat Xtreme applied to that panel would increase the loss factor to 0.417 @ +20°C (+68°F). Multiple layers of Dynamat Xtreme improve sound damping even more.Installation: Use scissors, knife or die to cut Dynamat Xtreme to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the release liner. The simplest application technique is to bend the mat slightly and attach it along its shortest edge. Press the mat firmly into place, using a roller for larger pieces. The roller reduces the risk of leaving air pockets, which reduce Dynamat's sound damping capacity. The temperature of the mat and application surface should not be below room temperature during fitting. Heating the material is not necessary.
