Dood!

I am using a Sony CDX-M750 with 3 internal crossovers and a healthy 50Wx4 of
real watts, 4 infinity 3.5'' speakers in factory locations behind factory
grills, a Bazooka 300W sub amp bridged driving a bazooka dual-voice-coil
10'' speaker in a Q-logic enclosure.  The compact cube sub sits behind the
rear seat facing the rear window -- I would not put a sub in a van facing
the front.  The front speakers give me excellent imaging.  The sub is
crossed at 125Hz and the sound is quite impressive.  Bach, Kraftwerk, Pink
Floyd or the latest dance music all sound dynamic and I get a healthy dose
of bass down to 20Hz.  Yah.. it makes my rear-view mirror vibrate and my
nose hairs tingle.  Even my mom loved the way her CDs sounded in my Westy.
BTW, The sub is small enough so I can easily move it to the floor for
camping.

No, I would not omit the front speakers.  It's like putting a TV in your
house... behind a shower curtain.  Put larger 5 1/2 speakers in the front
doors, preferably a 2-way separate set up, if you're wiling to hack your
precious door panels, quality 3 1/2 in stock rear locations and a small sub
behind the rear seat.  That would give you excellent imaging and a
full-range sound good for any type of music.  Any more than that is overkill
in a relatively noisy vehicle like the Vanagon.
