Easy install
5 out of 5 stars
Easy install
Very easy install. Backing is adhesive and sticks very easy. Make sure you line up the peicr before pressing down or you gonna have a hard time tearing it off to realign. I’m by no means a professional at this but it definitely was t difficult. In terms of sound deading I honestly can’t tell a difference however maybe after I do the rest of the car I will notice the difference we shall see.

Product stuck very well immediately and was easy to flatten using any flat firm object to fit into all sizes to properly adhere. I was also incredibly impressed by the integrity and helpfulness of the owner who kindly and quickly resolved a unique situation I encountered. The sound of my new speakers is much enhanced and there is zero vibration when I crank up the tunes. The grid measurements on the backing made it simple to cut out equal sections. And for custom spots I simply overlayed the paper side and slowly cut off pieces until I had a perfect fit! Then strip off paper, align and stick. Pull up and adjusts easily if need be. Rub flat and presto your soundproofing is in place. Double layers were no problem either right behind my woofer to ensure proper sound proofing. You will love this product. Can't wait to use it again on my next project.

    This sound deadening was as easy to install as any other sound deadening you can buy. The adhesive was strong yet malleable. It made a great deal of difference in the cabin sound and resonance for my single cab truck. I was looking to get the most bang for my buck by using a head unit and some decent speakers (no amp), so I figured adding sound deadening would help make the listening experience better and I can say it definitely did! The doors also sound more "solid" when you close them which is nice. Still have more to do, but simply lining the doors and door panels made a great deal of difference. I won't do audio work without adding this from here on out!

    I used this to help deaden the road noise and enhance the clarity of the sound system in my Jaguar F-Type convertible.
    Such a great product. Easy to apply, good quality and sticks well. I have only done the two doors up to now, but I have to say the difference is night and day.
    The Meridian sound system in the F-Type Jaguar has been given a pretty bad rap. But to be fair, the system is great, it was just drowned out by the road noise and the supercharged engine. And the F-Type is a very loud car.
    But now I have this product and seen how easy it is to apply, I plan on doing the whole car. Although, just the two doors being done has really impressed me.

    I started a small cargo van conversion over a year ago. This was one of the first things I purchased for that effort and I've gone through two full boxes so far. I've used it on almost the entire rear of the van with the exception of the two sliding side doors. The floor, walls, ceiling, and rear doors.

    It definitely deadens vibration and reduces noise slightly. However, I don't think my van has turned out any quieter at high speeds. Maybe I'm expecting too much. And to be fair, I haven't installed this anywhere in the cabin area, the front doors, or the engine firewall. In the back, I'm using it in conjunction with foil bubble wrap, foam insulation board, and fiber insulation. When combined with all of that, the impact on noise is significant. Of course, stand alone it is acceptable and eventually I will finish install on all other possible surfaces in my van. Price wise, this is unbeatable compared to the name brand, but I'm not sure how it compares on function. A professional audio tech could better review that.

    It does a very good job at reducing noise and are easy to install. Do get a good set of rollers and make sure to clean the surface with alcohol. I will be buying more. Wish they offered a thicker version but they do a good job at reducing low frequency noise.

    I bought this to deaden the sound in my parents' RV. It's an older converted van with the engine compartment extending into the cabin. I used this to completely cover the inside of the doghouse (engine cover), and the noise levels dropped considerably after putting the cover back on.

    It is easy to trim using scissors, and the adhesive is strong after the piece has been pressed down firmly. I was impressed with the price and delivery was relatively quick.
