Dude you crack me up . Its been 2 weeks since you started your build thread, and you are on V3 already.
You'll be happy with those IDQ's, my all time favorite sub.
FYI: Your box is still way too big. IDQ's love a very small enclosure!
I put 4 IDQ 10's in a customers Duramax several years ago. Unfinished pics of the box I made.
Box volume was right at around .45cuft a section. Note the box was essentially 4 separate sealed enclosures, and was very very stiff. It produced phenomenal sound.
