I am wondering if I can remove the half DIN cup and the region of plastic that holds it in, would there then be room to fit the Empeg unit?

I thought the same thing with my 94 Civic but there isn't enough clearance for the cords and you would need to build a custom mount for the second DIN unit.There is some space behind the cup for cords but not nearly enough for all the connections the Empeg needs. You would be better off putting the Empeg in the existing DIN slot and using it as the master and slaving the second head unit through the Empeg. That way, you have fewer cords going up and you should be able to store the unit in the space. Removing the cup holder is a must though for this project.

You might want to take it to a Pro Installer and get their opinion as well. They may have a more crafty way of putting the second head unit in.
