Just a helpful tip on sound deading your trunk.

Go buy some of that paint on truck bed liner.... It raises up while it cures and will completly eliminate any rattle you have... Also will give your car that really nice low sound to your bass... It's really clean sounding.

This work 3x's better than dyno mat and is about the same price.

i used something like dynomat
i don't know the brandname...
i can ask it though
it's like dynomat but thicker and cheaper... => better

the effect is really nice

also great improvement is foam in your doors

my door panels rattled all the time

i took em off and put some foamy stuff between the panel and the metal of the door it rests on (at the top)

the foamy stuff was just something laying around in my garage, i think my tv was wrapped in this stuff on delivery...
it helped a lot!
you can still feel the doorpanel vibrate but there's no more rattling...
=> mission accomplished!

Duct tape is a thin form of dynomat. I had a friend do his tails and his plates with it and the rattle went away.

I used some sound deadener that's probably very similar to yours. I got it from Rick at http://www.elitecaraudio.com and it works great, but I've still got some rattles in the back panel of my trunk, because I can't figure out how the panel comes off. Sometime soon I'll figure it out and sound deaden what still needs to be sound-deadened on my car. By the way, is the foamy stuff like bubble wrap?

i couldn't figure out where my rattle was but then i took my spare tire out and loads of washers and bolts were down there rolling around. i took them out and now its fine.

yes coomer the foamy stuff is something like bubble wrap... sometimes electronical devices are wrapped in bubble wrap sometimes in a foamy wrap...
i didn't use real bubble wrap of course... the you'd hear bubbles burst when you turn up the volume


the panels in the trunk of our cars aren't that difficult to remove!
once you know exactly where the plastic is attached to the chassis it's a piece of cake
you just have to be VERY CAREFULL when you do it the first time otherwise you can break some of the plastic part holding everything together & you don't want that to happen...

there is another foam that works like the bed liner stuff but its cheaper. plumbers use it when they need to fill a hole that they made adding a pipe to a brick wall. it comes in a spray bottle. i dont know what it is called but it works great. me and a freind of mine have used it some installs it works like a dream. you spray on a thin cote and it expands. you can get it any hardeware shop.

mass load, brace or isolate.

mass load = make it so heavy that it doesnt vibrate any more.(whatever you can stick on it)
brace = think of a big piece of sheet metal. brace it in the middle and it will be harder to make it flop
isolate = stop it vibrating against something(foam,rubber etc)
