On my '79 the speakers are behind the q-panel (it just has holes for sound no grill). I have not removed them or gotten in their yet but it is in my future as I have a dud for music and no original fader or radio.

There is a write up on taking the panels out somewhere, I did not bookmark it. IIRC, you have to remove the q-panel retaining screws (2-4 screws, I think) then push the panel forward towards the engine but not lifting. Pushing it forward will allow it to be lifted forward and out...then access. The rear seat may have to be out of the way??
