For a build this large that SPL is the goal you should be using 1"HDF throughout the encloser. The metal brackets are awesome. Good work on those. Get a really good silicone caulk for the joint inside the box. Coat the exterior with fiberglass epoxy.
Drivers that large and horns are a waste in the doors. You should have for example some JL Audio ZR 8 + 6.5 components in the doors. Run two 15" RE Audio xxx in a large ported box. No bandpass. You are choking those subs in the bandpass.
Without being rude I will have to kindly disagree with 99% of what you said. HDF/ MDF is crap for enclosures. the only reason I even used a little of it was because it was already in the garage. Choking subs with a bandpass is possible, if not properly designed or tuned. However this is not the case. My front stage is full active with the 10'' crossed from 50-400hz ported, 8'' sealed playing from 400-4000k and the horns playing 4k+ with an 18dbslope. This is not an SPL build either. This is just my daily driver. And silicone for the joints is also terrible as it does not bond to MDF/HDF well if a all. And incriminator audio will walk all over an RE audio **** today. 9-10 years ago they were neck and neck when David was running RE, now theyre straight chinese garbage. The new XXX is alright but still nothing compared to the old.

Ignore the haters. When I get my build log up, you'll laugh at my setup.
But, its very nice so far! Looking forward to some more posts and pictures. I know I haven't heard it, but unless my eyes are deceiving me, I think it wouldn't hurt to maybe have some tweeters or horns in the dash?
But, its nice seeing a audio build like this, you dont see them too often up here, at least the ones who lift them too.
