Here's my project for the day: Install the tweeters from my set of separates into the door.
I originally planned to make tweeter pods to go up by the mirror, but since I didn't feel like fiberglassing anything, I decided the space between the vents and the door handle would be a good spot to mount my tweeters. I checked and there was abundant space, so I went for it.
Here's the spot I decided on.
Step 1: Figure out your placement.
Step 2: Trace it with a sharpie. Luckily for me, I had a hole bit in a drill kit that was the right size for this. I wanted the hole to be a bit bigger than the tweeter, because I would snug it in with the door covering.
Step 3: Drill a pilot hole in the center of your circle. Be careful!
You don't want to shred the vinyl covering on the outside of the door. All drilling/cutting/whatever takes place on the inside of the door.
Step 4: Drill your hole for your tweeter. I really suggest getting a hole bit like I used to make a nice, clean cut.
