I just had two 12" JL w6's installed and I'm getting major rattling basically everywhere in my trunk. Is there any other options to help stop the rattle besides the obvious Dynamat, Fatmat, Raamat, etc. Is there anything in particular in my trunk that I should remove, tighten down, tape, etc. Help me out guys!!!!

Most people are going to tell you to do what you don't want to do. There are so many threads on this that I coudn't possibly provide what might work for you.

I normally don't like doing this, but, I recommend that you type "Trunk Rattle" in the Search feature located in the menu bar at the top of the page. There will be several pages and it's possible you might come across one that works for you.

Good luck!

you have to use some type of dampening in this trunk. but there are things
you can do that dampening will not help.

1. the rubber vents in either side of the trunk will flap as your bass plays,
this noise is very audible. I've removed them in my car. Beware the
are flaps so that they let air escape in one direction and keep moisture
out in the other direction. So far there haven't been any problems with
me removing them.

2. adjust the rubber stops at the end of the trunk lid so that the trunk
shuts nice and tight. Be careful here. Too much in the outward direction
could stop a rattle in one place and cause the rattle to move toward
3rd brake light.

3. wrap electrical tape around the latch. be careful not to make it
too thick or your trunk will not close properly.

4. This is a very tight area. Get some closed cell foam (such as
weather strip material from a hardware store). Reach underneath
the car, between the bumper and rear fascia just behind the license
plate. Wedge the foam in between. This is extremely tight. If
you have access to a body shop, you could remove the rear fascia
and apply this to the bumper, then re-install. This will be very effective
to solve a rattle that will not be resolved by sound deadening alone.

5. Take the same weather stripping and add it around the trunk lid where
it contacts the trunk. your trunk lid is going to vibrate with bass, the idea is to stop the vibration from making noise.

Still say you need to consider sound deadening, but these should help.
