What's a dynamat?

My trunk rattles like its gunna fly off from a 12" HX2 power and I was wondering if anyone has dynamatted their trunk. Reason I ask is when I poked around in the trunk I couldn't figure out how to place the dynamat w/o cutting it into smaller pieces (Which would nullify the purpose of dynomat?)?
Pictures of it installed would be awesome!
Dynamat is a sound deadening product. There's other brands also.. A good solution to trunk rattle is to Dynamat the trunk (even if you have to use smaller pieces, it should still help) and to also try to tighten up the trunk latch. You should be able to adjust it.. Other people I know of have done this to various models of cars and it has helped a lot.

I know this thread has been dead for a while, but I just wanted to add something....
There is nothing worng with cutting dynamat into pieces and using it that way. You don't need to lay it in large pieces (although that's easier, it's not really more effective). You just have to make sure that you lay them edge to edge. I dynamatted my trunk (actually I used Brown Bread) and it helped tremendously. I actually Ordered some Raammat to do more and to do the floor in the cabin as well.
dead thread but.... dynamat doesn't have to be in continous peices or even stuck together. In one of my useless college classes we learned about resonant frequency. That is the frequency at which an object is 'excited' and vibrates massively. If you put dynamat on, it changes the resonant freqency, so that part will get 'excited' at a lower freq. With enough damping you can get it down to 20 Hz, at which point it is a non issue.

This spring I'm going to sound deaden just the passenger and drivers side floors. You think 12 to 15 sq feet would suffice?
I just want to cut down on a little engine bay and road noise...and minimize the sounds from a catless dp.

I just purchased 36 square feet of Dynamat Xtreme from Ebay for around $125 which is half the price in stores. I plan on doing the trunk and all 4 doors at the end of this week. I will tell you guys if it really makes a difference when I'm done.
I bought 62.5 sq ft of Raamat on ebay for 90 bucks. I think he frequently sells them out there. It's a great altertative to Dynamat.
Cool as the other side of the pillow.
Yep, here we go. He's got an auction going right now.

i'm looking to do doors and trunk floor.
curious as to what you folks found was an adequate amount.
right now im having all four doors dynamatted with dual installs, and a single trunk install. im putting a 4x80 memphis into memphis 6's and 5.25's in the car, with a 1100 watt memphis amp driving a 10 inch image dynamics sub in a .9cu.ft sealed enclosure, will let yall know how the dynamatting sounds with stereo on/off relative to what the car sounded like yesterday.
gettin it back tomorrow.........
I'm doing it more to quiet the road noise inside the cabin. especially on the hwy
yeah im doing mine because im an audiophile mostly, but I will let you know how it sounds without any music on, see if it quiets the ride down at all
Ok guys I finished the trunk today and used 8 out of the 9 sheets of Dynamat Xtreme which is 32 square feet. I covered everything I possibly could in the trunk and it actually makes the trunk look a lot cooler too. The kit the company makes specifically for the trunk is absolutly ridiculous. There is no way they give you enough to cover the entire trunk. If you are going the Dyanmat route definatly buy the Xtreme bulk pack. Anyways I think the other sound dampening stuff works just as good as the Dynamat if you don't want to spend as much cash but the Dynamat Xtreme looks the best IMO. I will probably buy some speaker kits next and I will tell you how that went as well.
