Has anyone used Dynamat or any other sound deadening material in any of their cars? How well does it work and is it noticeable? I will be upgrading my sound system soon and might want to stick on some of this stuff.

 

It's essential IMO. Start with the doors as it makes very big difference there.

 

I also used some in the trunk as well.

 

I've used sound deadening products from http://www.b-quiet.com/ and have found them to as good as Dynamat and at a lower price.

 

That sounds great! Thanks a lot guys. I know it reduces vibrations, but can I stick it on anywhere for the side and rear view mirrors to not shake as much? Simply driving without music vibrates the rear view mirror so much as to where I can barely see out of it. I'll tighten it, but that won't do much justice.

 

You need to screw thee rear view mirror the wrong way to tighten it.
