Here's some ideas...... DIY-er stuff that can get you started without dumping a boat-load of money. I'm a big DIY-er guy....... to take as far as possible and when I can't make it happen anymore, then I pay someone to do the rest.


Wires...... wires rattle everywhere. Go through the trunk with a billion zip ties and make sure EVERYTHING is zip-tied down ...... EVERYWHERE. Under the rear deck in the trunk sides...... dig up everything. Wiring can even be found behind the pillar panels in some cars. Some guys go as nutz as EVERY 2 inches there's a zip tie and the wiring is wrapped in something like black hockey tape to cut down on any buzzing. *drink* Dollar store has zip ties cheapo.

Back deck....... remove it and put the box in again to test out what is rattling (after you have zip-tied everything down). If it's good, then check out the deck itself and look for loose bits. This is going to be about securing EVERYTHING down super tight.

Bumper and licence plate........ annoying to some.

Let me know how it goes..........

IF your back deck vibrates like crazy, gets some foam mat and install it between the deck trim and the metal deck. But it has to wedge in there tight.

Best job I EVER saw was the guy that cut two holes in his roof and mounted the subs ontop of his roof firing into the car............ magnets exposed to the elements. *th-up* Took my vote as the Best Install Eva.

use a sound deader like dynamat. take out the carpet from the trunk and put it down properly and then the carpet back. should take care of the rattaling.

heres an example of a trunk done with it

Dynamat alone will NOT get rid of the rattles.......... under most normal circumstances. The application of this sort of material is often misunderstood and people spend way too much dough on it................ to an installer that has no clue. There is no quick *fix* to rattles.

^^ I agree it will be hard to get rid of all the rattles. To do a whole trunk in dynamat can get very expensive. I never heard of the zip tie technique but I am going to try that our when I install my subs.

A way that I have used before to get rid of the rattle for the licence plate and it will probaly work for the decklid too is too put like a kitchen sponge between the metal and the plate and the metal and the decklid. It will cut down on the rattling but still may not eliminate it all. Just buy packages of cheap sponges from the dollar store *th-up*

hope this helps...just some things that i did..i took off the carpet with toolbox on the trunklid...and stuffed the insides with old tshirts...so the trunk lid was nice and tight...i also tighted the trunk down with the 2 knobs that control the tightness...i also put a port(3.5") on the back deck(above the rear seats)..so that it could take away some excess air..and the system sounded a lot better actually with the port...and i put rubber behind my license plate....that killed the rattling...the metal plate behind the rear seats create a lot of rattling..so i just cut mine out...no1 really sits in the back seats(seats are back in place)..and put lockwashers on the rear taillights..cuz the vibration makes them loose and they also rattle..i have no dynamat in my trunk and its just fine(with all those mods)....but that worked for me...goodluckkkkkk

It will definitely help though. e36 spare wheel wells are thin, and Dynamat (or equivalent) will reduce the rattling.
