headliner and trunk issues

[neverfinished]

i was to pull down my headliner to dynomat my roof, can anyone tell me what i will need to do and how hard this will be?

also my trunk ratles some, i have put alot of dynomat back there and its pretty good, but it just doesnt seem to be able to handle all the presure, i'm wondering if u guys think it would work to put like a foam insilation in the area where my trunk seals to my car, do you think this could reduce my rattle and help seal my trunk better for more bass?

I know there are threads in here about this. I remember one a while back about the trunk latch not holding tight enough and creating a lot of rattle. That and dynamat is not a cure all. Sure it reduces the rattle enough so that you don't sound like a tin can being beaten as you roll down the street, but you will still hear it if you crank the system and stand next to your trunk.
