So I've had a brain fart and have came up with this little jewel to save my door speakers.....it's made out of antifreeze jug
I just cut out a good size square with about a 1" strip of the side of the jug,then I slit the strip every 1/4" or so....using my calibrated eyes
This is to let the plastic follow the contour of your doors hole
On the depth of it I just trimmed till it just touched the back of the door skin
After I got it trimmed like I want it I mount my new speaker and it holds the rain deflector in place.
