Opening up my late MBP I messed up the membrane of my left speaker, an authorized Apple repair center quoted me 650 euros to replace the entire top case (the speakers are glued to the body of the MBP). I managed to find a set of speakers for 70 euros harvested from a dead machine, so it is possible to remove them. I was wondering if anyone knows what is the best way to soften the adhesive holding the speaker in place? Do I need to use heat? Is it the same glue use for the battery? Do I need to get the battery solvent from ifixit? Thanks!
