Speaker Adapter Thickness and Other Comments & Qs

1) I just installed some 6.5s in my front doors (infinity component system). I used 5/8" MDF to build the adapters for the speakers and of course the adapters were too thick (door panels won't press into place).

Do I have to use that flimsy 1/4" MDF for the adapters? Anyone know how thick you can go?

I *wanted* to use roughly 3/8", but couldn't find any small sheets (didn't want to buy a 4'x8' sheet for two little adapter plates, so I used a piece of 5/8" MDF shelving.

There was regular plywood available in the lesser thickness but - why is MDF the material of choice? Better density?

Also - Is it advised to enclose the entire baffle? I was sealing the mounting surface of the adapter to the plastic OEM baffle, then the speaker to the adapter, but all that seems somewhat overkill when the baffle is open in the rear, allowing the speaker to bounce all over within the doors.

Yeah but he is using the factory plastic piece to mount the MDF too not just the door.
