Greetings!

Some folks I know at work are working on getting an empeg and a second head unit (for tuner and physical media) installed in the dash of a 1999 Honda Accord. I see that it has been sort of done before, but a few questions:

a) Is the factory opening dual DIN, or is it 1.5 DIN?
b) Has anyone succeeded in getting two DIN units installed?
c) Is there a special mounting kit that can be used to get dual DIN working?

Any comments, recommendations, suggestions or ideas are welcome. Fortunately, the person doing the install is much more competant in this than I am, but I am on the board more (thus I am posting).
