It’s been a while since your post here and you’ve prolly found answers since. So I post this now for others who might have need for this data.
In ’93, overhead speakers may have been standard in the GS and optional with the amplifier in LS models. Dunno about ‘92 or ‘94.
To access/remove these small speakers, first turn off the dome light switch.
Then gently pry off the center “lens” (the one with the opening for the light switch in it). Remember; old plastic often gets brittle after a decade-plus in service, so pry easy.
Remove the bulb and the single bolt from the center of the speaker housing/grille.
At this point you should be able to see the speakers, if they’re installed,
Disconnect the 4P connector for the dome light.
Remove the two screws that attach the speaker mount and disconnect the pair of 2P connectors for the speakers.
A single screw attaches each speaker to the common mount that holds both speakers. There may be another pair screws, one each for a pair of speaker connector/wire retainers, or maybe just one.
Hope this helps.

Actually, I haven't touched the dome speakers, since no one responded previously. Thanks for the assistance!
So does that mean Vigor GS's have 8 speaker setups? I noticed there are dash speakers right at the windshield, so that would count with the headliner speakers, dash speakers, front door speakers, and rear deck speakers. I'm impressed for the audio on a car made 13 years ago.
