You will have to get the back seat out first. First you pull the bottom part out (there should be instructions on how to do it on the net, u just pop it up) then u will have to unscrew the back (there are 3 screws on bottom) and then push it all up so it comes out of little plastic latches which are on the top behind the seat back. What u then gotta do is remove the actual parcel shelf. The speaker covers are glued into it. From memory when I did mine, i think i undid the seatbelt plastic trims that are attached to the shelf, unscrew the child seat hooks if u got any, and then u need to pull it out somehow, being careful not to bend it to much as it might crumble. It's easy to figure it out anyway. Once u take it out u can access the speakers easy. Good luck!
