I had some time to install the gasket material on the BavSound subs and I had some extra Dynamat in the garage. I installed the Dynamat and the gasket and the bass has more punch but my wife was outside the car when I was listening inside the car and she said it sounds horrible from the outside. I stepped outside the car and when the bass note is played there was a rattling noise coming from the bottom of the car. Reminded me of a license plate frame vibrating on the back of a car when a bass note was played. I was wondering if you are having the same issue. I could not hear the rattling while inside the car only when I was outside. My thoughts are, the bottom of the sub enclosure has a hole in it and the floor board where the sub enclosure attaches also has a hole. Now the hole inside the sub enclosure is now closed do to the Dynamat being placed over the hole. I am thinking I need to either remove the Dynamat completely or at least from over the hole in sub enclosure.
