Has anyone installed speakers on the hatch door? I was thinking of putting a pair back there and throwing in a couple 4 channel amps for the 8 speaker setup

 

Will have to look at the 6.5s last time I opened it up, I don't think there's enough room for 6x9s, but could be wrong.

I've always thought about doing that, kinda like when jeep did it, I believe it was them who made a drop down setup on the hatch.
