How do I remove the rear deck speakers out of a 92 Bonneville? Also, Really sorry to hear about the car.

Just take off the covers and undo the bolts. (Or are they screws? Can't remember...)

They are bolts. Getting at them is difficult though, because the carpeted plywood cover gets in the way. I ended up hacking it up so I could get a socket in there. Of course with the speaker cover on nobody knows the difference

I never had any problems getting mine out.
