Sweet! I also believe the 6.5's firing into the seat won't matter, because the dash speakers do all the imaging & staging anyway.
Where did you put the 15 in the trunk, and what kind of sub? That's the one thing I haven't a clue how I'm going to do yet... how to get a whole pile o' bass without losing my whole trunk!
Have any photos of your Jehnert or subwoofer setup?
Thanks again,
