Here you can see where the butyl has stretched, easily cut with a sharp knife:

I was surprised by the butyl rope used to separate the door brace/safety-bar from the outer door skin.. nice! This saves me from buying the butyl rope..

I cut and applied the RAAMmat to about 75% of the outer door skin. I added an additional layer of mat (about 8"x8" square) behind the speaker driver location. I lightly tapped on the door and other bracing, listening for ringing or anything that would have rattled (using odds and end pieces of the RAAMmat here):
