I'm happy to tell you that I had good success with the rigid insullation I fitted into the stepped own section of the trunk. I used Johns Manville rigid insullation 3 pound spun glass, number 814. It is 2" thick and comes in 2'x4' panels. Not easy to find. I made a template out of cardboard and cut the 814 on the table and band saws. It really was effective and removed a majority of the annoying frequencies---not all, but a bunch of them. The 2" thickness actually did a nice job of leveling out the floor in the trunk of the M Coupe. I'm sure more sound deadening will go further and I suspect placing more 814 along the back bulkhead behind the seats would really do the trick, but, for now, I'm going to take it for another test drive. Damn itchy stuff to work with when using saws.
