Make it a snug fit or use some 3m tape. it'll be pretty easy to figure out once u start working on it.
The installation manual for your tweeters will show you now to mount them to a panel.
1. Make a perfect circular hole larger than then back but smaller than the front flange.
2. Remove metal ring.
3. Insert tweeter from front, the front flange will be tight against the panel.
4. Screw ring on from the back, this clamps the tweeter in place.
5. Wire tweeter normally. I recommend adding a quick release harness so you can remove the panel.
