Installed 3 of these kits in my car. The highway ride is noticeably quieter, the car doors now shut with a resounding thud instead of sounding like a hollow aluminum can. Much less rattling from subwoofers. Good stuff.

Used with with the 36 square foot kit to get my truck done, and it makes a big difference in sound, road noise and sound clarity, if your wanting more bass without having to upgrade your system you will want this.

A bit heavier than expected which is good considering it's use is to dampen vibrations in resonant panels. Buyers should keep in mind that the best use of this product is on 50-75% of the surface area of a body panel to effectively reduce vibrations; that's it. Completely covering every surface is a waste of materials. To effectively sound treat your vehicles interior you should be looking into not only this type of sound dampening product, but also into mass loaded vinyl to attenuate road noise and help contain the music from your speakers as well as closed cell foam (Ensolite®) which acts as a sound absorber and isolator of the MLV and the door panel. Also, look into modeling clay and proper speaker baffles to install the mid-bass driver to the door securely.

OK, if you have the need for stealth sound quality, you must buy this product. It is by far and away the single best investment for improved sound quality. I will further emphasize that sentiment if you have large doors or vast amounts of open sheets of steel body.
I did a test once on a cargo van door speakers with the stock stereo. I installed these dampening sheets before installing the new speakers. The sound quality difference from adding the sheets alone was much, much greater than swapping to the new speakers.
I will always use this product anytime I replace speakers or open up a door panel. It is really a phenomenal product.
BTW - I've used the other super expensive brand also, and this is the same stuff.

Went on easy and does a great job of insulating and soundproofing. My 1979 doors now close and sound like a new car. Has made a major difference in road noise.
The only reason I didn't give it 5 stars is the price and the only reason I did not originally purchase it. I did though get a special price because of a problem with the product I ordered. I guess it was a win overall for me and a chance to review a good product.
