well this new amp makes my car THUMP. and it moves so much more air my trunk rattles alot more so i bought "great stuff" expanding foam and did the trunk lid. it acted more like a glue than anything else and "glued" the trunk sheet metal to the frame. so i have that under wraps, now the panel where the licesn plate is is taking all the brunt of the pressure and rattles like whoa. but it seems to big of a gap to use the foam on and it accually work. any suggestions? im not going to mat because i dont want all the weight but i hate rattles. also behind the pillar plastic covers rattle. any ideas on a light weight way to get rid of this? DONT SAY DYNAMAT, but anything else is cool.

Turn the stereo down...that will work ;)

You know there is super lightweight Dynamite...

More than likely most of the rattle is coming from the licence plate, since it screws in the top but not the bottom...so the bottom is probably flapping.. Your idea of putting something soft under it like small pieces of foam in the corners then screw it down will probably work.

If you were really concerned about weight then why do you have a thumping stereo ? ;)

i used the little strips of insulation foam that you're supposed to put on your doors and windows if you have a draft coming thru

its sticky on one side with some decent adhesive (but not too strong)

available at your local Home Depot or Lowes

its not huge. its a rather small box accully, its just that i have it facing the rear of the car and its quite powerful. but i can take it in and out with ease. i know its heavy but i took the spare wheels out and i dont want to add more weight to it. and i put those felt pads they have for the bottom of chair legs on the bottom of my plate and bolted it together on the bottom as well. its the rear panel of the trunk, im going to try some of the foam and see it that wont work, if not ill figure something else out. as for the pillars im going to take them all off and see whats lose behind them and put some of that stick on insulation just to silence it.

Dynamat it........and get more horsepower. :)

Deep down, you know you can't have it both ways. That's like asking how to build a 10 second Sentra that gets 45 mpg.

I just used four screws to hold down my license plate. Drill 2 extra holes, pad the back of the lic. plate, add screws and call it a day.

.........what?

its more or less true though. i have found a few things that could work that are lighter than dynamat, there was a vynal damping stuff i found, it most likly wont work quit like dynamat to help increase sound, but im sure it would get rid of rattles. but im looking for cheap ass (typical b14 owner here) getto tricks. and let me say the expanding foam (great stuff big gap filler) worked perfectly on the trunk lid it wont rattle at all now because it is either 1mm away from the under bracing or the stuff foam wont alow it to move.

the next hurtel is the rear where the plat is, that may be tricky.

We plan on using this for the upcoming audio install articles.

Check out the compare link... vs dynamat in weight and sound deadening

They have several versions.. We're going with the lightest.

go to home depot and see what you can find, you can get amazing ideas. i would think something like a sticky backed heavier rubberish vynal would work great. the roofing section may be a good section to look in. just pull the piller cover off and put a sheet on the inside of it and press into any crevaces.

also an expanding foam may work for you, i used large gap filler by "great stuff" you may have better luck with the small gap filler. this stuff comes out and expands (like hair moose.....exactly like it, a dime sized dab of moose will expand almost the same size of the foam did) but this stuff is very very VERY sticky. get some and experiment before you use it. it get pretty solid and will prevent anything it is attached to from vibrating.
