Default Sound deadening

What have you guys used for sound deadening I know there is dynomat and fatmat and others have used rolled roofing. What other possible off brand sound deadening material is out there that works and is at a reasonable price. Thanks in advanced.

I used these guys and their product worked well:

though they're not quite as cheap as they used to be. I did an install in my '08 about 6 years ago and has held up perfectly. Just had my doors apart a couple weeks ago to upgrade the front speakers and it looked the same as the first day I did it.

whichever brand you go with... PLEASE dont just go with the cheapest. You really do get what you pay for in most cases. Do your research and choose wisely. Lots of good products out there but there are also lots of products that are just a waste of money.

I used this stuff on my 71 VW Westy and the difference was amazing. Before doing this, while on the road I could barely have a conversation with my g/f. After covering the entire interior paneling with Bquiet it really decreased road, engine, and exhaust noises. Now I can actually talk and have a conversation with passengers in the back no problem.

Highly recommend from personal experience with this stuff. Price is pretty decent if you ask me. I will likely be doing my suby with this stuff to try and eliminate added NHV from poly bushings, group-N mounts, etc.

Cheers,

I used a combination of CLD tiles from http://www.sounddeadenershowdown.com/. A 10"x10" or (12"x12") of Dynamat for behind the speakers and then some HVAC insulation material. The Dynamat I bought from Amazon and HVAC material from Home Depot.

I basically mixed and matched from several sites including http://www.sounddeadenershowdown.com/how-tos.

Good luck and keep us posted.

EDIT**

Here's a link I posted a while back. It touches briefly upon the sound deadening materials I used. (As well as the background/organization of the install process.)

when deadening the key is to use the right product to get the end result you want.

If you want Mercedes/BMW "thud" when you close the doors, then you want MASS, aka peel-n-stick tiles. Do a checkerboard and save yourself the $$ you don't need 100% coverage. 100% coverage will be fine, but not absolutely necessary. On the roof of my '04 WRX Wagon, I did 100% and the rest of the floor, doors etc I did a 6" x 6" tile checkerboard on everything. Taking a 12" x 12" tile cutting it into 4 squares. Been doing this for 15+ years and impossible to count # of cars.

Next is the Mass-Loaded Vinyl Barrier. MLVB is basically a non-adhisve backed heavy foam with a vinyl final layer. THIS is your road noise killer. Wheel wells, outer door skins, trunk / lift gates etc. If I could find a MLVB that was adhesive backed like peel-n-stick I would put it on the roof for sure. Since out cars have a board-backed head liner you use CC (see below) spray glued tot he back of the headliner board instead.

Next is the Closed Cell Foam (CCF)which is your road noise/rattle initial barrier.

'showdown has some good hints and information. The original site was TONS more informative. But once he went into business selling product the content has suffered tremendously.

If you REALLY want to go crazy, spray on deadeners for the insides of the wheel wells, and over checkerboard peel-n-stick has proven effective and weight conscious for Jeep owners.

Just depends on what your expectations and concerns are. attack them head on with the correct product.
