Blowthrough through back glass of truck

[daltone34]

So. I just got a camper shell and plan on doing 6 12s in a blowthrough through the back glass of my truck and I have a question. If I were to build the box like the picture on this post, would it be considered a sixth order or would it be fine to build it To the specs of a ported box?

That would be an unloaded 6th order

Seal up the rear and make the front a port for a 4th order

Also you should be able to fit 12 12's no problem with a design like that

Or you could do flat sealed wall with the 6 and port through the window

This is 6 15s in a 4th through the back window in a friends truck.

See I tried a 4th order with an 8 just to test the sound and all and I didn't really like it.. they're just too complicated and unless you meter it while you tune and build and such then you'll never get the sound and pressure you want.. and I've never really liked a sealed box but it just depends on how much air I could be pushing if I did do a flatwall sealed.. would I just do a regular sealed wall to specs and leave the window alone? Wouldn't it act kind of like if you had a c pillar wall with seats (the back wall) in the way?
