You're right there called sail panels. And your also correct with the install. You'll cut holes the size of the flush mount tweeter cups. Then place the tweeter cups inside the holes. Glue them in place with an epoxy mix or other very strong glue, whatever you can get your hands on. Check the fit and see if its flush or not, sometimes they fit flush and sometimes they don't it depends on the tweeter size and shape as well as the sail panel you've got to work with. Then you'd sand the panel down preferably with a red scuffing pad just to give a little grip to the plastic so the body filler and paint can stick to it. Then apply and smooth the filler as needed. If you had to much of a gap for the tweeter to be filled by the body filler you would want to us an mdf ring thats been trimmed to fit or a piece of pvc around the cup and glue that in place. Check the fit with the tweeter every so often to make sure it sits flush. Once it looks the way you want you can paint it with a matched vinyl and plastic paint you can find at O'reily's, or if your really up for the task you can coat it in a color matched vinyl. If you go the paint route make sure to apply it in multiple thin coats. That's how I've done mine on my past two cars in the and how ill be doing it on my GP soon.
