I know your trying to maximize your airspace, but have u actually calculated
what your going to get by eliminating the indention's in the factory box?

I first thought that too, but realized i would just make the box weaker.

Plus the airspace is right in the middle of where the kicker woofer requires so
its okay. I know with more airspace you can get a deeper note, but if u
want that then you need to go ported to notice a difference anyways.

It's that whole "is the effort required worth the reward" conundrum.

Mine hits nice.. but not as big as my past setups.. but i like the whole
stealth install look in vehicles. It's a shame you cant come see/hear it.

For the cover rattling, I cut the square woofer shape out of the plastic cover
and have it stick thru. Looks good. Only thing I'd change is make the woofer sit
out a bit more so its fully seated in the plastic cover to look snazzier. I may do that this summer...
maybe.. as it requires me to make a wooded "washer" the shape of the woofer to make it stick out further.

Ill post a pic of my cover later... that is if I'm not too late to add my $.02
