i just put dynamat all in the trunk of my car and behind the license plate and everything and yet it still sounds like it is farting when the bass is all the way up.. Anyone else have a del sol and know what else could be rattling?

 

i never dynamatted my sols ,, only rattle i had was the trunk welds eventually popped off due to the system. open your trunk up , look at the bottom of the trunk lid and see if the structural skeleton on the underside is still glued to the lid ... if its not .. theres your rattle .
