CANOPUS Professional Car Sound Deadening Self Adhesive Mat, 80 mil (2 mm) 10 sqft Butyl Sound Deadener Mat Audio Car Sound Dampening for Car Trunk, Door, Floor and Ceiling, Sound Deadening Mat Black

Did the job as described, made a massive difference to the audible vibrations whilst driving and a nice addition to my driving experience. My forza speakers sound better too since. Can’t go wrong

Great stuff, works well and easy to cut and apply. Certainly quietened my 206 mini countryman when applied to the underside of the bonnet.

Easy to use and great quality.

Used to reduce internal resonance from a PA system subwoofer cabinet. Seems to do the job well - however adhesive is not best suited for wooden surfaces - stapled in place for extra security

very good product it did make difference how my car sound insulation interior

I got these to improve the sound insulation of my camper van bonnet. The mats are easy to cut with scissors or a craft knife and, as they are self-adhesive, they were easy to apply exactly where I wanted them. They are very effective at cutting down vibration and noise.

This has literally turned my Toyota Auris 2010 from being almost a shell leaking all my audio out, to literally soundproofing it to the extend you can blast the bass and can’t hear too much from the outside. Not only that but the sound quality has improved drastically now keeping the bass in from some cheap £20 pioneer speakers! A must have if you are improving speakers in your car! Very easy to cut and apply You are supposed to clean the surface. Most of it I didn’t and this stuff hasn’t moved since I installed it!

Good value & prompt delivery. Have used this product before and was pleased with the results

So to start I have degreased anything that wouldn't promote adhesion and they still don't stick very good. I have also rolled over the product with a roller to promote better adhesion and it almost made it worse at times. I'm not sure how long this will so a further review in the future may be necessary.

Upon opening the box I had that “this is going to be messy” thought. It is simple to cut, peel, and place. And it doesn’t stick to you or your scissors but very much to where you put it. Sound reduction is noticeable.

Perfekt zum entdröhnen aller Blechteile am Fahrzeug. Habe damit einen Kleinwagen und einen SUV gedämmt. Es ist ein spürbarer Unterschied.

Ottimo prodotto, molto pesante e di qualità.

I apologize for the more blurry pictures, it was a screenshot from the video. All in all, great product. The adhesive on the back is extremely strong. It's very easy to cut if need be. It does perform really good when it comes to sound deadening. I can hear a bit less road noise and no rattle after installing just the little bit on my door behind the panel. I'm sure if I did the whole door panel it would block out so much road noise. Definitely will buy more for any future products! It helps a lot with sound, especially bass. It makes the bass sound a lot cleaner and tighter!
