Hey guys, I have a pair of JBL 660GTI in my doors. I installed them about 4 years ago. Recently I decided to add sound deadening to my doors. When I pulled off the door panels to apply the sound deadening, I discovered that the panel sits too close to the woofer in the door and is damaging the surrounds. I'm looking for ideas for how to create more space in front of the woofer. I think I'm probably going to have to cut the panel, but am open to other ideas.

That's an interesting idea. I don't want to replace the driver, but I might consider having them refoamed and invert the surround.
Is that an enclosure behind the speaker or just an adapter?
I can see the oval-round adapter you made, consider ways to inset the speaker another half inch or so. Use a Dremel, router, even a hack saw. I used a Dremel with a 1/8" drill bit on medium slow speed, and a hack saw blade to modify those plastic things.
You'll probably have to modify your adapter, or make another adapter, possibly a two-piece, to mount the speaker back in place.

Contact cement glue an extra set of speaker gaskets on top of the existing ones to add thickness and separate speaker,including its foam surround, from actual panel cutout.
If unavailable or impractical to order (postage 5X the actual part cost), make your own out of EVA spongy rubber, 5 or 6 mm should be enough , maybe 8mm at most.
You just cut narrow strips , bend anf glue them over the current ones.
If you want to get fancy/sophisticated, use cork.
Just do not tighten mounting screws so much that you compress the new gasket to zero thickness 😉

Use a pair of spacers made for increasing clearance behind a speaker but mount them on the front of the speaker to prevent the door panel from hitting.
You can also try new cardboard spacers on top of the surround, recone suppliers sell that stuff.
I was thinking the same thing as Perry. Mount the speakers to the back side of the spacer if you can. That will give you plenty of clearance. Otherwise you have to buy an aftermarket speaker spacer that is set up for that. You may be able to modify the current spacer to accept the speaker on the back side of the spacer versus the front of the spacer.
I think they are called inset spacers or something like that.

I just found these, and think they might work. They are designed to be mounted onto but I could mount them in front of the speaker instead and that would prevent the door panel from pressing on the surround.
