It is a 6.5" speaker be carefull though because it is a shallow mount speaker. If you are talking about the rear roof speakers they are 4x10 and you push gentle from the rear forward on the grille cover till the black tabs are free then pull down and back and the covers are off. Then take the four screws out then the speakers come out.

To remove the speaker grilles in the rear of a Mark VIII gently pry up on the lower forward portion of the speaker grille. Do not forceor pull on the grille, just pull it slightly out from the interior panel and then move your finger under the grille along the lower portion and up the back side. This SHOULD dislodge the clips that hold the grille in place. Now pull down very carefully on the entire grille assembly and it should be free of the interior panel. Now there are four TROX screws holding the woofer and two for the tweeter....
