Well, you could probably relocate the tweets up into the A-pillar and the mids you might be able to put in that panel by your feet. Might be easier to go smaller. Say like a 4" instead of the 5 1/4".
Yea thats about the only idea Ive come up with thus far too. The only downside to putting them in the lower panels is Im going to have to keep taking that on and off in order to connect/disconnect the wires for the doors.
Maybe bundle all the door wiring into a quick connect/disconnect plug and just leave them where they are?
that may be possible- heres the write up for doing it all, after looking at it again, Im not sure theres even enough room behind those panels to even fit a speaker.
