Black kick panels with speakers

Sorry guys for not replying sooner. I forgot I had listed the panels for sale and hadn't looked at my post in a while. The speakers and grids are screwed to the panels. I'm not sure how deep of a speaker could be mounted on them. The guy I bought them from told me the panels were originally from a 69 Dart. For some reason only one of the panels has the hole cut for the speaker and the other one does so one will still need the hole made.
