Dynomat(sp?) sound deadening. Does this stuff really work?

[SillyClown]

I could have the wrong name or mispelling of this product. My problem is this: I have a '95 eagle Talon and it has an alright factory speaker system(Infinity). I have a pioneer deck(45x4 ch). Well I decided to include a little bit of bass to my music listening experience. I didn't want to over do it and look like some of the idiots that go driving around here. Individuals here feel the need to take there beaters and turn them into a rattling theater for the neighborhood to hear. There trunks rattle something horrible with every bass note that is projected. Anyhow, I just put in two 8" subs in a small custom box I made earlier today. I hook everything up and it sounds perfect. Not too much bass and a good mix of mids and highs. But here in lies the problem. I kept my car running and stepped outside to take a look at the amp and box while the music played. Well right when I stepped out there was a bit of that rattling that I hate so much. It's not a lot and it's not really loud, but it's enough. Now does this dynomat stuff help with this sort of problem? Or is this product for something else?

Thanks for any suggestions, comments, etc that anyone may have. I am not at all an audiophile so please don't flame me because I like my factory speakers

Why don't you jsut tighten up whatever's loose in the trunk?

I use the stuff...It basically prevents vibrations in larger body panels....doors, hood, deck lid. Won't prevent rattles in other body parts. Tighten everything down....lay carpet material everywhere you can. It'll help.

i used dynamat in the trunk of my old car, and it helped dampen things a bit. But it's expensive.

If it's not a plainly visible body panel vibrating, you might be better off with "spray foam" sound deadening stuff....it just kinda hardens up and fills space where things rattle.
