what size of speakers will fit in my 1999 GMC Jimmy 4dr?

[Epic]

My speakers are rattling. I need new ones. What size are they?

 

[Jester]

just like KaeZoo said it 6.5 or 6 1/2 size but make before making your decision on the speakers that the depth of the speakers won't hit anything inside the door like the glass or the window mechanism i and believe the maximum depth is 3.5"

Just get rid of the old speakers and
listen only to Mozart at a very low level.

Your Jimmy uses 6-1/2" speakers in the front and rear doors.
