help with installing fornt and rear speakers

i am have a little bit of problems installing my speakers for my 89 grand am le. i cant seam to figure out how to get the back dash off. it seams to be glued on there and i cant get to the rear speakers from the trunk. please help.

You'll have to remove that back seat to get at them.

thanks brandish i didnt think i would have to go through all that trouble just to get to my back speakers.

i changed the 6x9's in my 95 GA and i not only had to remove my seat but i had to remove the side panels as well and i STILL had to force the back dash to come out. Im not sure why GM made it so difficult to change something so easy.
