The supposed port does not go in to the B pillar, as there is sound insulating foam there.
Having a small, sealed enclosure should also assist in their power handling - when amplified.
Midbass sounds far more accurate (less boomy) in the sealed enclosures and I've fitted a pair of inductors which has removed the high-end superbly (thanks Jim!).
FYI - my X3 has 6.5" midbass - not 8"! The top looks 8" but the woofer itself is a 6.5"!
It's sounding pretty darn reasonable now, with the staging back up just above the centre of the dash (inductors worked wonders with this) - just need to sort out the loud mid's with some more EQ...






What did you end up using for the inductor value on the under seat subs?
