hey guys, My R53 06
MCS has the HK system installed, Now the problem is not the speakers itself but the brackets and fancy grills around them coming loose, i dont wanna have to drive for an hour into the city and them have the car for a whole day just to tighten a few screws,its happened twice already and its only the left side

so i was wondering how i can remove the shround myself ? any ideas of how i can get to it ?
Cheers
Callan
