Finding stock replacements are difficult (and expensive) The speakers are 6 1/2" round. The door speakers are the same size. You can purchase most any speakers, but make sure they will fit the depth. The rears seem to have a good amount of clearance, but the speakers in the door are VERY tight. I used Polk Audio db 650's in all four and they seem to work well. They are about 2" deep. To get at the back speakers, you need to remove the rear seat and then remove the side trim panels.
How do i replace subwootfer 2002 xj8
6.5front & 6.5 rear
If its a convertable, remove the the screws under the rear seat and remove. Then remove the screws holding the leather enclosures and remove from sill plate. remove the speaker boxes and replace. If you don't have new speaker boxes remove cover a speaker box, access speaker and replace, you will probably have to solder the wires, then reverse the order and put back together.
6.5 inch front and back.
6.5'' Front 6.5'' Rear IIRC
4x8 in the front and 6x9 in the rear
Rear is 6 1/2''
Front Speaker Size- 4"x6" and Rear Speaker Size- 6"x9"
I did this with my 1996 Lumina APV. If you have rear speakers, remove the speaker cover(s), remove the speaker and reach in and find the mechanism, turn it to open. May have to do simultaneously for both sides. Then remove the tailgate panel and repair.
very very deep
