Siless Max 120 mil (3mm) 30 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material (30 sqft)

Used this product to deaden a pair of large speaker cabinets, great product to work with, used a pair of metal sheers to cut and trim the material which worked well, cleaned the MDF and it adhered very well too. The speaker cabinets sound much better now, when knocking on them they sound much less empty or hollow, playback sounds cleaner and has less echo as well. Overall very pleased with the outcome. For application I also purchased a metal roller which was a must, I couldn't imagine applying this much by hand alone.

Used this on both my F-150 and Honda Civic. Did the floor pan, doors and back wall in the F150. It’s nice that it’s 50% thicker than the thin stuff along with the Aluminum coating for some heat dissipation . It was easier to install than just plain butyl rubber in the summer heat, the indents made it easy to see when it was properly set and rolled and easy to cut. Definitely recommend for the price point. Made a huge difference in exhaust noise and the sound system sounds much tighter as well as a result of less vibration and noise intrusion. I used this in combination with the Siless Hybrid to cover both vibration reduction and sound infiltration.

Muy buen material, le quitó lo tembloroso a la carrocería de mi auto, también lo aisla del calor y del ruido... Recomiendo ampliamente!

Great quality! A much needed product for a quiet drive.

Easy to work with, quiets doors very well, cuts very easily to any shape needed or wanted with scissors, sticks well, and molds in to place well
