I've just sent an email away to SHOK industries to see if they can tell me the displacement of the woofer. fingers crossed i'll get a reply.

So here is a suggestion, had to pick a smaller net and a slightly higher tuning to almost fit your dimensions, wood thickness set to 18mm, power: to sub(s) rated, amp subsonic filter to 28Hz, minimum port clearance 9 cm, figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.

45s as follows if you want to do them:

Cheers Joe X,

I'll make up in cardboard and check, I have a large trunk opening to work with.

just to note the displacement of the woofer(s) are .13 cuft per sub so .26 - my last calculations were based on .3 so pretty close.
