Speakers in doors?

Hi. I realize the auto makers never really cared about good sound in the 70's, and the one speaker in my dash sucks. My interior is in very good condition and I'm worried if I cut the doors I'll be some kind of bad f body owner. I can't put them in the kick panels because the car is a standard and I need the parking brake. Any suggestions? Or just go ahead and hack the doors? It's a 76 coupe. It's already got upgraded rear speakers and I just added an Alpine head unit
