Speakers

Ok im planning on replacing the speakers in my 92 z28 and i have a friend that says he'll do it for me if i buy the speakers and everything so i was hoping somebody could tell me the number, size, and location of the speakers in my car.  Thanks

rear's 6*9 back by rear seat's front's 4*6 under the dash

so there are 6 all together: 2 6*9s and 4 6*4s?

2 4x6 under the dash, 2 6x9 in the sail pannels standard. There were Bose option that also put speakers in the kick panels. But you would see them there if you had that.

Yeah my little trunk cover thing has holes for speakers and covers that say bose on them.  is that the bose option? if so, what size are they?
