so my trunk makes the system sound like crap on the outside i was thinking on gluing some foam around it but not sure if it would work anyone have some ideas?
you dont need to glue it, its self adhestive nub, and fatmat is just as good, and much cheaper! thats what i use. it holds up in the heat pretty swell. idk how it handles cold yet.
second skin SPL tiles. seen them and they work. pricy but its for your trunk so you wont need too many. the other stuff mentioned works too. what do you want to spend on deadening BTW?
There is also peel and seal you can get at lowes, I got some more the other day.. a 50 foot roll for $16.97 it's in the roofing section. I can tell a major difference since I added it.
