Use a dull flat head screwdriver and carefully pry the side closest to you up (farthest away from windshield)enough to see the metal clips going down into the dash, position the screwdriver as close as possible to these metal clips to avoid breaking the plastic that holds these clips on. once you have the metal clips clear then slide the cover away from the windshield, you will see the two slide in clips that hold the front in. To put the covers back on slide the two front clips (closest to windshield) into the holes, then line up the metal clips with their holes and snap them into place gently. To remove the speakers use a stubby Phillips head screwdriver to take out the four screws that hold the speaker down, be sure not to place them on the dash since they will fall into the windshield defroster holes very easily. After the screws are out just pry out the speaker. Installation is the reverse of removal.
