Good insulation mat

This is a good insulation matt for the value. I think this is the best for the buck. It's easy to cut, shape, & sticks very well. Can't say anything bad about it.

Unsung hero

often overlooked,but given the price and performance of this kit,i say its a must have for everyone who wants to uprgrade their door speakers. Brought out the most out of a 40 dollar alpine type e component set.(also from sonic) :)

Great Value for what it does

Made a noticeable difference on the vibration coming from my door panels. Also covered up some huge gaps that were around my speaker so it even sounds like I got a little more bass response in the cabin.

Great product!

Made a huge difference! Stinger Sound deadener really made speakers louder.

Big Difference

After installing inside my door panels, it made a huge difference in the sound quality. Eliminated the rattle from the subwoofer.

Much needed

Good for lining doors for mid speakers. Keeps the rattle down

Thick Sound Absorbing Material

Clean area first, and make sure you have a roller. Nice adhesive, but you need to be patient to roll out the material to cover the area thoroughly. Does a good job with the vibration on my Harley fairing. I would recommend the product.
