removal of Bose door speaker amplifiers from 89 C4.

Any information on removing Bose speaker amplifiers?  Removed the door cards, miscellaneous rods, locks and hardware, but still can't remove the speaker box and amplifiers.  Are they glued in to door panels or what.?

I found that the Bose speaker amplifier units in the door of my 1986 were attached with 4 bolts and were sealed with a type of very sticky calk material. I very carefully worked a small putty knife around the edge of the housing from the inside of the door. Once the seal was broken I was able to carefully pry the housing loose. Good luck working inside the door can be challenging, lost some skin off my knuckles.

yep they use some damm good adheasive caulk but they come out    I put some pioneer round speakers in the bose box   with a little help from my air saw and sheet metal  good luck  that took up my whole weekend
