here is what you need to do. go to the hardware store and buy the expanding foam that they use to seal windows in homes. . there is a black "under bumper" under your bumper cover... spray lots of the foam between the cover and the black plastic piece.. this helped mine immensely. and i am running about 1400 watts.

My car sound like major crap!!!!!!!!
all it does is rattle really loud outside the car when the bass hits.

does anyone know what is rattling and how to stop it?
it seems like the bumper is rattling and the exhaust too.
i bought some undercoating so im gonna coat everythign really really good. i hope it will quiet something down.
any help would be great.


thanks

You just have to have the system bumping and you have to listen for where they are. That'* why dynamat was invented as well as filler foam to stop those rattles.

I layered my trunk w/ dynamatt extreme but i think the bumper is still being a pain. il look for the filler foam the closest i found was undercoating.
