hi guys, need some advise just fitted front and rear kenwood 200w speakers on my 2001 model xsara. they are still alot better than the factory ones apart from a annoying vibration in most the door panels when i have the slightest amount of bass, what would be the best way to solve this problem? could it be loose door panels or maybe the speakers vibrating on the original speaker covers that i had to put over them? any advise would be great, thanks
