Ok, I think I bought something too quickly before thinking, LOL.  I just bought the factory subwoofer enclosure (and sub).  I've got an SEL without the audiophile setup.  So, my question is, I know I can just screw it in there, but what about the trim panel that installs over it?  I know with the factory setup, that cubby is not there and there is speaker grill cloth there.  Has anyone added a sub to an edge without the sub and what have you done? 
  
Any suggestions?
