I installed a Rockford Fosgate T400-4 with Polk MOMO10" subwoofer in custom enclosure, etc. It sounds absolutely amazing except there's a panel that's vibrating when the subwoofer is at certain frequencies.

The panel is the one behind the seats just below where the roof connects to something - it's the rear panel of the area where the roof folds down into. The problem is that I can't figure out how to get the panel off and I don't want to risk cracking/breaking something as it seems like the panel is made of hard, almost brittle plastic. How do I get the panel off to add some soft insulation so it stops vibrating?

Any help will be appreciated. Thanks.

 

People have removed the soft top tray or covered it with dynamat. Moving to Electronics subforum.

 

So how to remove it? How is it secured?

 

there are a lot of little .... tabs i guess? you have to depress the middle, and then you can pull out the whole "tab"... do that all the way around and then you can remove the soft-top "tray"
