I used the plastic OEM speaker mounts and although it took a little effort, they worked great. Photos of the front 6x9's. (I ended up going with a three way system so these were removed.)
As you can see, I sealed these with silicone so its a pretty permanent installation. The foam around the front of the speaker is cut from pipe insulation. It seals against the inside of the door panel. I had to trim about 1/4" off the plastic flange on the door panel so everything mated tightly but did not interfere with the door panel fitting against the inside of door properly.
