09 ceiling speakers

Has anyone actually scene them? If so what size are they I have thought about upgrading them I have a set of 6 1/2s sitting arround and was thinking about putting them in the doors for now till I get some 6 x 9s ( that is if 6 1/2s fit in the door). But if they fit in the ceiling they r going there first I like having speakers above my head but the stck ones suck. I have done a bit of searching but can't find out much info besides disconnect them and run speakers to the rear door. Anyone got any answers?

 

Take a look at this site. (you will need to get an account to see the pics).
This is not my post. I'd be interested to hear if you figure anything out. Those ceiling speakers really do suck.

The ceiling speakers are little 2.5 " computer speakers. There are spaces in the rear doors to mount speakers.
