Hi does anyone know if the factory subwoofer grill can be popped out of the parcel shelf as mine is non stop creaking so want to remove it to attempt to remedy the issue by re-seating. I don't really want to have to remove the parcel shelf trim complete as this will be a lot more involved!

 

A match book as a wedge fixes everything. Sorry Aaron, I just could not resist the urge.
I would not want to remove the shelf either. The creak would drive me nuts too.

 

I have wondered myself about wedging things in it! It's literally like a flexing creaking sound that is almost constant it's literally driving me nuts!!
