While that install looks amazing I'd like to just butt in here and mention that shallow drivers aren't necessary at all. I have CDT Audio ES-6s (6.5" drivers with full dept) in the front doors of my Golf with no sizing issues; I just have to use 1" spacers. In the rear doors (I have a four door) I slapped in Peerless SLS 6.7" mid-bass drivers with no sizing issues.
Shallow drivers may be slightly more convenient here but they aren't necessary at all.
that is very interesting. do you pics of waht you did? becuase i know from personal experience that most beefy and powerful midbass have that issue.
if you use a 1" spacer, how far is your surround from the door grille? is it possible that your door grille is hitting the surround with out you knowing it? a quick chaulk test will confirm.
refer to this thread for waht i mean:
having spent over 3 hours just trying to get a set of Arc audio black series to fit into the door of another mk6, with measurement up on measurement, find routing it to make it thinner to make it work, i am surprised you an so easily fit a normal 6.5" with a 1" spacer....beuacse a 1" spacer is what i started with and the surround hits the grille on excusion. i ended up with a 7/8" spacer and shavbed the grille a lil for that to work.

in either case, my point was never that other midbass are unfittable, but this is a sure fireway to easily fit a mid that has the output performance, the impact and extension, without having to spend time worrying if it will fit and carefully crafting a spacer with precision.
