help- rear speakers
 

im at a loss. ive owner my 2000 oldsmobile intrigue gx for about 6 months. no major issues. when i bought the car, the passenger side rear speaker was blown so bad that you could barely hear out of it. in the last 6 months the driver side rear speaker has blown as well.

i bought new 6x9s.. and fully planned on replacing them myself as i always have in the past. but ive got NO idea who to get at these speakers. it isnt from below. and the grilles are attached to the big top carpet piece. i dont have fold down seats and for the life of me i cant figure out how to get that big top piece out of there. help? please?
