Fix for - HK Premium sounds horrible from outside

The sound of the HK audio system from outside the 1er is horrible - rattles and vibrates when the volume is moderate-high. I am aware this is a known issue. What I am after is someone who has managed to solve it, and how please? I have searched and come up empty. Please do not hit me with the "turn down volume" or "get back in the car" lines. I am after genuine advice and a fix if it exists. I was going to dynamat the area around the under-seat subs and the doors - would this work? Which panels actually vibrate causing this? Thank you in advance.
