Troubles installing rear speakers

[Sov13t]

Hey guys ... once again its me..

Im having problems trying to take off the trim above the rear speakers... when i pulled it upward the plastic snap in bolts/screws all snapped out in the middle... but the entire panel is still being held on the left and right side of the car where the seatbelts are... I can not see any screws on the panel.. and I am afraid to pull it to hard... So I am wondering if anyone has done this before and what I should do...

Thanks.
