I've done almost this exact mod, except my 4" speakers
up high are just cheapo pioneer units, and the 6.5's
down low are coaxial infinities.  At the time i was
happy with the 4"s, but now i can tell that they can
get pretty shrill in some instances.

>The 4" speakers have a passive filter (just a cap) on
them - didn't really notice much of any difference.  I
bent the handles slightly to clear.
>The 6.5" speakers fit in the bottom of the door panel
(just barely) with no sheetmetal cutting.  It was a
close fit.  The map pocket did have to be clearanced
around the speaker, but i don't notice that in
practice.
>The 10" sub in back adds some oomph.

The best bang for the buck is the 6.5" down low.  It
really adds to the richness of the sound - especially
if you are not an audiophile.  A big ol' sub is just
showing off :-)

I really do enjoy the way my van sounds now, but there
is only so much *bump bump* that i can take from that
sub, so if i were to do it again, i'd probably be
happy not having it in there...

Hope that sheds some light,
