i used at dynamat trunk kit for about 70 dollars.i have 2 12" alpine subs.mine pounds like crazy.before i put the kit in it sounded like s--- b/c of all the rattles.i had it coming from the tire well,sides,license plate,everywhere you can think of i had the rattles.now i have no rattles,awsome crisp bass!that s--- really works!

o boy did mine rattle with 3 12's 1000watts lol idc though didnt play it real loud no rooms for subs to hit hard.

i got 3 12s and 2500 watts <BR>yeah it rattles out side but man its loud inside

What kinda amp is pushing 2500 watts?

us accoustic 1000d pushes 2500w max at 1ohm at 12.9 volts<BR>im pushin about 2000 rms @1.3ohm at 14V

wow, thats impressive

I've still got a rattle somewhere in my door (the latch I think), but here's what I've done to reduce rattles & road noise:<P>Spray ruberized undercoating inside the doors and under the plastic panels in the hatch area (be careful & mask the area off). Lined the inside of my door pannels & tire well with polyester batting. Put all my tools that stay in the car in a fabric bag & aranged so they don't clunk around. Taped down all the wired inside the door with double sided padded tape.<P>My exaust had some rusted clamps on it, so those got replaced too.<P>polyester batting works better than sound mat for rattles, but for general noise spray or mat is the way to go.

my buddy has a probe that rattled alot from his system and bought some sound damping sheets, they worked better than i had expected and theres very little rattle, so ya guys might wanna try that. oh and i have the same rattle problem too and will be buying some of them sheets myself. ebays got them for pretty good prices.

go to lowes and buy some stuff called Peel-n-Seal It works and looks like dynamat extreme. Its good stuff if you are putting it on the spare tire area and floor.

i have tried a lot of stuff i think my rattles are here to stay but it sounds good in side so who cares what the other people here

i had 2 12" mtx in a ported box before which got stolen. anyway that setup rattled every part of my trunk, bumper, hatch and all. anyway i got a 10" solobaric. it sounds much better, and hits way harder, with tuning, and i barely have any noises now. im guessing its cuz i its sealed and one smaller sub vibrating in the trunk will make less noise as 2 or 3 subs.
