is it possible to wire up the oem cd changer to the oem stereo and at the same time wire up the in dash cd changer to the oem stereo too?

its the #1 and #4 photos in the link.

 

It should be possible, you could plug the changer in on older Honda's even if you had the cass, deck added the the oem radio, cass. deck plugged into oem radio and CD changer plugged into cass. deck, [daisy chained] although because it is an indash changer, it may not have the multi disc changer input.

Why not contact them and ask if the indash has the changer input port on it? 94
