speakers in door panel on saturn

[Benny212 10+ year member]

I just bought some infinity 3 ways and installed them in the door of my 98 saturn SL2 for some reason anytime the woofer moves at all the door vibrates, even when it is at almost inaudible volume. The stock speakers didn't do anything like this, I think it might be because the infinitys have a much larger magnet and are much heavier, but other than that I have no idea what is causing it. I'm hoping that one of you experienced guys has seen this problem before. I just ordered some RAAMmat (cheap dynamat knockoff) from ebay. I'm hoping that will help. One thing I have tried is making a little ring of open celled foam to put between the speaker and mounting surface. it helped a little bit, but still horrible vibrations happen.

Thanks
