Cranzy my understanding from researching this stuff is that it is mainly for vibration and as such does not need to fully cover every panel are you able to comment on this. I am also under the impression that a proper sound insulation rubber mat would cut down sound more than what you have achieved?

I'm under the impression dynamat isolates in such way that less noise can pass in or out through it. It is usually used for better sound performance inside the car, but it also cuts down road noise and such.

I haven't tried the rubber mat because I didn't have the energy/patience to put another layer on top of what I did. I would assume it will give you better isolation though since the factory OEM mat doesn't go past the strut bar.
