Maybe the 83-1/2 and 87 are different then.  I can see no screws.
The door speakers are same as rear cabinet speakers, both have
plastic clips that spring out when speaker is pushed into location. I
checked the manual and it describes a process of removing the A/C
venting -- around 20 screws under plastic caps, then lowering the
rear cabinet to gain access to the speakers -- a major job.

Maybe the ones with screws are aftermarket replacements, but I'd love
to know how to get the OEM speakers out of there without
dissassembling most of the rear cabinetry and A/C.

thnx
