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.

perfect - makes a massive difference to the van sound, bought 2 packs for a transit custom. might need another pack to finish if I do the front and side doors. its quite heavy so I can understand why they dont do this out of the factory. get yourself a good roller. I regret not getting a better roller.

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

Excellent product

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 is good value for money and the black finish looks nicer than the usual silver. Seems to have done the job required too.

Really good so far. Has stayed everywhere I’ve put it. Lining the front cab floor, roof and doors of an older model transit which has a lot of road noise. Worth buying the larger pack!
