Anyone had issues with the inner door panel rattling when playing music at louder levels. I have my Utopia's crossover set at 63 hz, and at certain notes I can hear a very noticeable vibration/rattling coming from the passenger side door, seems to be in the middle of the door or towards the front. Anyone have any good suggestions on eliminating the unwanted noise. A friend of mine mentioned putting balled up socks between the plastic panel and the metal door panel. Any other suggestions or fixes? I have a ton of dynamat left over, and I read online its recommended to dynamat the inner plastic door panels too, but dynamat does not get rid of rattles, only reduces unwanted outside noise.
