Good quality and can't beat the price. Its half the cost of dynamat and is a thicker mil which means more sound deadening. I have a 1000 watt RMS 2000 watt peak subwoofer and it would rattle everything. NOT ANYMORE! This kit did all my doors (4), roof and trunk area! Look no for further for a good sound deadener. I would buy again.

as stated this is a fantastic product and the price is unbeatable! It is very dense for the thickness, conforms very easily (I recommend using a heat gun as you roll it for ease of install), very sticky and most of all it works! Installed in my 92 K1500 which was a complete rattle trap to say the least... The stereo would have everything in the truck flexing and rattling so bad I didnt even want to listen to it anymore... I applied to main problem areas (roof, inner door skins, rear wall of cab) and wow what a difference! Sounds so solid and very little exterior/road noise (and I have 3" exhaust and super 10 mufflers)... Will soon be re-installing the stereo equipment so I will update my review to let it be known the improvement there

Very good product. Eliminated 99%of my trunk rattle. Be careful of the aluminum edges as I cut my fingers several times. Adhered very well. If you're installing on your trunk lid u may find it necessary to upgrade the lift supports because this stuff is heavy. Would definitely purchase again if needed for a car audio install.

Got the job done. No more rattling

Very happy with this stuff. So far I have only used it on my two front door but the results are outstanding. Very easy to cut with a utility knife, sticks very well and folds around bends and corners of sheet metal much easier than I was expecting. I used two layers on the outside door and 3 layers behind the speakers with a foam pad on top to absorb back waves. Then i put it on the inner door and sealed off all of the holes including the massive hole that the manufacturer leave to service the window mechanism...hope i don't ever have to get back in there lol... I tapped on the outside of the door and then the other side that wasn't treated yet and the difference in resonance and vibration was substantial. I also gained a SIGNIFICANT amount of midbass from my Focal 165 k2 speakers. Also big difference in road noise. Still have plently left over to do the trunk when I get some more time. I'll be using NVX sound deadening in all installs I ever do from now on. Do not spend thousands on great speakers, amps, processing,.etc. without proper sound deadening and install. Excellent quality at a great value
