Ok i'm just ready to put my system in(2 12" kicker L5's) and all im looking for is a cheap sound dampening product that i can use in the trunk so it doesn't rattle my car. i dont wanna spend $50-100 on dynamat or fatmat when i can get same results with something much cheaper. now i heard corkboard is just as good. if there isnt anything else i could find at home depot i'll probably use that. list what u used to sound dampen ur trunk and any other good materials or tips to use on when doing my trunk.
thanks

First reply says "Your trunk rattles because the "Brace" or "frame" of your trunk vibrates against the outer "panel" of the trunk. So by insulating the area where they meet, or will meet, You've killed the rattle."

Other members are also using a shielding technique to prevent the sound wave from ever reaching the "brace" or "frame" so that it never gains enough kinetic energy to really vibrate against the outer panel.

Apparently choice number 2 is popular stuff. Choice 1 is for poor people. biggrin.gif

Any other noises can be related to items you are storing in your car. a nano-decibel may be accounted for with the trunks plastic/carpeted covers. But you shouldn't be able to hear those in the cab of your car; especially if they're attached well.

One other thing to look for would be your Jack. make sure that it; and all components are secured.

It is also possible that you have something in your spare tire bay. But provided that you do regular car cleanings, than it shouldn't be an issue.
