speaker size

[MustangGlx]

does anyone know what speakersizes go where in a 69 mustang grande?

Probably the same size speakers that go in a 70' grande.

If so.. then:

They are not common sizes. I believe the door speakers are 4"x7" and I believe the speakers in the rear package tray are 5"x9".

I had to do some slight sheetmetal tweeking in order to get 6x9's to work in the rear package tray. For the doors I just went with a set of round 4&1/4's
