Sound Deadening

I personally use dynamat. Some people will tell you it doesnt work and it is too much, but it has worked for me and is easier than trying to put 3 or more layer of the cheap stuff to equal 1 layer of dynamat. You get what you pay for, I'd go dynamat.

check out secondskin... ask about it on caraudioforum.com, the guy who is the "head guy" on it is always on and gives great deals for it. some of the best stuff around, u get what you pay for in other words. it might be a little pricey, but its worth it.

I have DynaMat in the front and RaamMat in the back. I prefer the RaamMat. The price is much better, you can get a good deal on eBay from the owner. It was ~$75 for 62.5 sq/ft. DynaMat costs about 3 times as much for the Original Series. RaamMat is equivalent to DynaMat Xtreme.

Take your time installing whatever you choose to use. I purchased the roller and it help. A blunt object like the end of a broom handle helps too.

The RaamMat in the rear helped attenuate the buzz and reverb inherent to the car's body panels. The DynaMat in the front helped to control the lower notes. The front doors actually act like sealed sub boxes.

Thanks, that's the type advice I was looking for.

If you are going to do the kind of setup spridget has, spring for the dynamat extreme instead of the original, it is worth the few extra bucks.

I've ordered the RAAMmat60, it was 79 bones for 62.5 sq ft.

It's a whole heluvalot less expensive than Dynomat, and seems to be comparable in performance.
I'll post the before and after pics, though it'll be a week, cuz its in Cali and I'm in Carolina.

Thanks for the advice.

Ok im not sure on how well it works, but the audio shop back in wisconsin uses roofing material as sound deadoning material and claims it works 99% as good as dynomatt...

AFAIK, Dynomat and roofing shingles are made of the same substance. Both of them are made of a tar compound that damps the sound. Dynomat is just a helluva lot prettier and a hulluva lot more expensive...

BTW spridget, how much would you estimate you used to do your trunk area? My brother is interested in buying half of the RAAMmat from me, but I dont want to committ to it if 30 odd square feet isn't enough.

I did everything in my trunk except for the spare tire well with 20 sq feet of dynamat extreme. Only reason I didnt do the wheel well was because I ran out. Th only other part I didnt cover was Underneath the rear deck. I covered the trunk lid, floor and sides.

I used about 20-30 sq/ft. Not sure exactly, but I have alot left over. I plan to finish the rear doors someday........ someday...........

The RaamMat doesn't stink as bad as the DynaMat. The only reason I used DynaMat in the front was because I had not researched sound deadening materials and DynaMat was the only one I knew of. RaamMat does stick better, does not require a heatgun to install, and forms fairly easily. I'm happy with the results. My trunk lid does not rattle like it did before. I have 2 12's in the trunk.

Good luck. I spent an entire Saturday cutting, fitting, and sticking the trunk and rear seating area.

When I used the dynamat I didnt have any smell from it. And all I needed to install it was a small roller to help form around bumps and edges, no heat gun required and it stuck great.

Don't waste your money on Dynamat or the others ... if you can stand a smell for 2 days go to an auto parts store and get rubberized undercoating. $4/can get 5 cans and your set.

Or pay $100+ for enough to do your door...

Question for you guys. I have the Dynamat Xtreme trunk deal, I dunno what it is I had it installed "trunk kit" is what the guy said. How much does this weigh? Can you take it out easily? Is it reuseable if I take it out?

I am selling my subs, and will take it out if it's a considerable amount of weight.

Any information would be appreciated.

It doesnt weigh all that much, maybe 10 pounds at the very most. Plus, it is a real pain in the a** to take out. They probably used a heat gun to put it in which melts this tar like suff on it and makes it stick really well. So unless you want to waste a good day or two scraping this stuff off and sctatching the he** out of your trunk, I would just leave it. Its not hurting anything and it does not weigh that much.
