The best way it to put matting on your rear deck and trunk lid. You can try dynamat or some other company and then install them.
i heard if i cut a hole or add ports in my rear deck that my sub will sound much better and my trunk will not rattle as much. can anyone back this up? i have a non-sport c230k and there is no hole where the rear armrest is. would this be the problem to all my rattling??

I just got (2) 12" Rockford Fosgate Power T1 subs in a sealed box. Then I removed the reardeck speakers and left that open and applied one layer of Xtreme Dynamat. And there is no rattle i can hear unless the bass drowns it out.
will this get rid of my rattling trunk?? i already fixed my license plate rattle but the trunk itself is still rattling
how did u take out the rear deck speakers?Originally posted by albanianbenz

The simple answer is you need to take out the rear deck. Please use search.Originally posted by ryhi

Yes, EXACTLY! Mine sounds like theres a piece of rubber or plastic, "flapping" around under neath the trunk. Is there any way to fix this, as it is so freaking annoying. thanks-Originally posted by audiophile

its the trunklid AND the flapping.
yea...what the heck is that flapping lol
i can't figure out what it is!
Are you guys talking about a sound heard from inside, or outside? Dynamat on the rear deck would only insulate the sub more from the cabin, am I right?
For inside rattles, try removing the black plastic tray inside the first aid kit area, it could be rattling against the sheet metal below it. Then, of course your first aid kit lid has nothing to latch to, which is a whole new problem. I know the lid to my first aid kit rattles quite a bit ever since the double sided tape I used on it failed. Also, make sure none of the speaker wires below the rear deck (between the carpeted surface and the sheet metal) are rattling against the metal. Felt and double sided tape can fix that.

When the rear deck rattle, you want to dynamat the surface between the metal reinforcement and the rear shelf. You do not want to block the hole. The dynamat will be a layer between the metal and the shelf so it will not rattle.Originally posted by vbrock1137

Please confirm that the whole holes have to be also covered by the dynamat.Originally posted by pnsji

Thanks a lot
Not for the real deck. You want to allow some air moving from the trunk to the cabin. This is how the bass created by the subwoofer could go into the cabin.Originally posted by 1998K

i dont think you can cover up that vent on the passenger side of the trunk (thats what causes the flapping noise on mine also) because it allows for pressure equalization when you close your trunk. i really want to get rid of those damn flaps though.

i think those flaps are for the battery, i.e. vent
So I assume this means they must stay... Damn, it sounds like a piece of linoleum floor tile is slapping against something when the bass is cranked. Ah well, the disadvantages of havingh a system...

thanks a lot, so you are saing that I cover with dynamat but keep open the 2 holes in order to permit the bass from the sub-woofer in the trunk?Originally posted by pnsji

BTW, matting the trunk lid:
Edit:
Here is matting behind the rear deck. Please notice that the speaker hole is not matted.
