Help Me with 6x9s plz!

Ive never owned a Grand AM and I cant figure out how to get the old speakers out of my new 96 Grand Am :banghead:. I popped the back seat out so I could get back there and now I cant figure out how to unmount the old 6x9's. Any help would be appreciated.

im not to sure about a 96 GA but i have a 2002 and i had to remove the rear dash and the speakers were just screwed in and i just unscrewed them unwired them and just put in the new pioneer 6x9s and put the dash back on it
