Just an update: They ended up going with the 12W6's in a custom box. I had an issue from day one as the emblem popped off the face of the sub, jackhammered the speaker between the seat, and cracked the sub. They just got a replacement in from JL and popped in right back in.
So now as it sits I've got 2 JL 12w6's, a MMats 6150D amp, 2 Hertz Hi Energy XL components, Stinger roadkill in the speakers and doors, and an Alpine W910 touchscreen nav HU.
I'll post some photos this weekend.
