Hi,
All,
I installed a Clarion MCD360 Crossover, and boast my bass up 9db at around 38Hz, and everything at the back of the my car vibrates, HARD.
I need help in what to do, to downsized this, the only thing I can get at this moment is dynamat Xtreme sheets.
Thanks
Regards

You need to isolate the rattles and then attack them. Crank the system up, and then see if the noise stops by pushing on the trunk lid, spoiler, tail lights, bumper, ect. When you know what is rattling then you can use either damping sheets like the dynamat you mentioned(there is good stuff out there for cheaper), foam, tighten up loose parts, JB weld everything solid(just kidding!).

Ttocs is right. Before you can eliminate them, you gotta get back there and find out where it is coming from and what is it going to take to stop it.
Dynamat and other sheets are good products but, sometimes will not eliminate the rattle. So don't spend any money on damping products until you figure out what you need. Like stated above, it could be something simple as tightening something up or using another type of material sandwhiched in between the culprits.

ive had very good experiences with (5$) expanding foam.

expanding foam should only be used with
EXTREME CAUTION!!!!!!
I have seen so many vehicles ruined by this stuff.
I have had customers with doors that wouldn't open, trunk lids deformed, tail lights pushed out of their sockets, wiring pulled apart.
Be so so careful and use it a little bit at a time.

of course.
this is definately the kind of stuff you a VERY slowly and VERY carefully.
ive never seen the stuff you mentioned because mine came out fine. but just by watching the potential of this stuff im not suprised.
EXTREME CAUTION

Great Stuff is good for many things. However, the expansion rate of this product is difficult to predict until one works with it a while. It's best to use it sparingly and in stages. (Ie: small shots, let it expand and cure, add more as needed)
While in the "green state", (Uncured) one can tool this goop with a puddy knife or similar tool. After it cures, a razor knive or file/sanding can be used to cut or trim excess.
Tech Tip: This is a very difficult product to clean up after. Acetone is the only product that will even remotely remove green state residues. After it's cured, abrasives will also remove residue on tools and such. Cover everything you don't want to clean up later. Once it gets into carpeting and such, it's very hard to remove... period.
