Speakers/Rear Seat Removal
 

I have a 1997 Cutlass Supreme 4-Door, and I want to replace the factory speakers. I am able to remove the bottom part of the back seats but not the top part. I have also tried to remove the screens on the top shelf but they are not removable from that way. I also can't figure it out from the trunk everything seems to be bolted in and I can't reach anything to unscrew it. Any Ideas?
