Rear Deck

Has any body replaced rear speakers in a 2001 olds alero, G.M. dealers said it cannot be done without breaking something..NEED HELP

i havent done them on that particular car but. let me ask you something, are the speakers on a rear shelf or are they in back passenger doors? If they are on rear shelf, pop the trunk and try to find where they would be. let me know what you come up with. it probably isnt that hard a job (though im not familiar with olds aleros).

Im not familar with the olds alero but it can be done
