Dynamat?
With my new speakers I've developed more rattles and buzzes than I can even try to identify and fix. I've heard people talk about Dynamat sheeting. Supposedly it helps to stop all that, but my rattles are pretty bad and I'm not sure if the Dynamat works as well as people say, or if it is just another fine example of snake oil. Has anyone else used this stuff before? If so, what were the results?

Dynamat is a good thing, but it depends on what's rattling. For instance, if you're shaking the sheetmetal of the door so hard it's vibrating, then yes, Dynamat will help. However, if, say, a plastic panel (like the door panel, or in my truck, the stupid headliner) is rattling, then it won't do a thing for you. For plastic panels, some big, thick foam weatherstripping wedged behind the panel works pretty good, as does that expandable foam stuff, but it's a mess if you ever go to take that panel off again. Best areas I've found to do in these trucks is
Dynamat
1. Doors (The inner door, right under the door panel, the part that the speaker bolts to)
2. The cab rear, behind all the trim panels.
There are some people that dynamat like the entire car, and I've never seen a reason, except it does help cut down on road noise, but it's real expansive when you start throwing that much Dynamat on...

I did the whole interior of mine with a single layer of dynamat...with a JL w7 13.5 sub and about 1800watts RMS...u cant really hear any rattling on the inside of the cab considering your brain is the only thing thats rattling. But once u step outside youll more or less know where its comming from. It works great for me...i took off my passenger side door dynamat off to repair the window assembly and left it off after putting everything back together...slammed the bass and heard nothing but rattles from the outside...Ive read in many places that its wise to spray on a noise reducer and then apply 1 layer of sheet noise reducers...but its all about what your gonna do with it...sound competition etc...if not I dunno

Parts Express out of Dayton Ohio sells a generic version of Dynamat that costs about $20 for enough to do the door of a full-size pickup. Sealing up the doors is the single best improvement you can make in sound quality for $50. It gets rid of tons of rattles there and in other places too.

if you can get generic dynamat its worth every penny. you will cut down on every kind of noise, and rattle. you will make your truck sound like a lexus....quiet. i did the entire interior of my neon when i was in highschool, and it was amazing. felt like a solid car. i did the trunk, hood, firewall on both sides, it was nice.

I remember reading somewhere that you are able to use a product called "ice guard" or something of the like. It is a roofing material and comes in a 2'x225' roll, for about $75 I think. I heard it is almost exactly like Dynamat.

I have put Dynamat all in my truck, but I am pushing around 165 Db's and the sliding rear window seems like it is about to shatter.

you should be able to use Ice Gaurd. it is the asphalt based material used to heat up rooves so ice doesnt build up on them. i havent used it, but have known people that have gotton good results.
as for 165db. ofcourse your back glass seem like it is going to shatter. you have what maybe 1/4 in. glass not 2 feet from the speakers. pull the whole back window out and replace it with a piece of inch thick lexan. lay some window tint on it, and you will be good. now only your side windows will shatter.

That's just too much sound for me. I like loud, but I like it to be natural with just a bit of bass. My system is very loud right now, but to get that little bit of extra bass I like I need to fix all the rattles and buzzes for it to sound clean.

My entire interior on my Integra is covered. Trunk is all Dynamat Super, the rest is Original. I go with what you know. Dynamat is great. I can knock on the front fender, then move to the doors and other panels and they are ROCK solid. There is no vibration at all.
