Are the rear speakers in the 94 an actual 6x9 or some odd size. I regretfully found out the front speakers are 6.25' s and not 6.5's. I'm not in the mood for anymore suprises. Will a standard 6x9 fit right in or will i need to fabricate some sort of baffle?

 

This is my 'replacing stock back speakers' story.
I wanted to replace my 6x9 rear deck speakers. After pulling the rear seat, third brake light and all that I finally got at the speakers *wow* that was not easy! Welp, the 92-96 rear deck speakers are 6x9 alright. What I hadn't known is the fact that they are Glued to a plastic base/adapter. The holes in the deck (the metal shelf-like thing under the cover Do Not bear Any resembalance to usual 6x9 speakers. The first plastic thing Slowly & Carefully came off and onto the aftermarket speaker ( a Sony, but they basically all mount the same) End Saturday.
Then the second speaker. The plastic bracket immediately fell into six pieces. I both glued it back together and emailed my Lex Dealer about buying a replacement. The speaker & bracket are considered as one part and is Slightly Over $200.- Good thing I glued the old one!
Well after alot of work and stress I have my improved aftermarket speakers. If I had it to do over again, I would have left the whole thing alone! The sound if the front & rear speakers is quite different and its almost impossible to get a nice even sound from the front & rears. Thus I say this:
Either have a professional redo the whole system or leave your stock system alone. I wish I had.
