I pulled the back panels & subs & foam inserts from my 2007 M coupe. The carver sub fits into a metal box/closure with foam insert. One of the foam inserts were incorrectly installed, I guess my car was built on a Friday. I decided to add dynamat to the inside of the box and to the inside metal mounting bracket. I noticed the subs are ported at the top of the box were air is forced in the rear cabin behind the storage bin. I always wondered why I heard vibrations in that area. I think the system sounds much better in the rear; I don’t have the same vibrations behind the seats. I only spent 4 hours and the dynamat was cheep because C-city stores are closing so I got it for 70% off. The true test will be tomorrow when I take it out and drive it for a couple hours.
