I have a need for good tunes in anything I drive.  I consider the fact
that even if the vehicle leaves me sitting on the side of the road...i
still have my music - so I've always gotta have a nice system.  I
imagine the dash dimensions are the same for the Westy as the Vanagon.
I have an 85 GL and my Alpine am/fm cdplayer with its own can slipped
right into the dash and fits like a glove...didn't even need to put an
adapting faceplate on it.  It's rated for 30amps x 4 and i power just
the rear speakers on it (which need replacing - any suggestions please
let me know!) and power the front speakers and subwoofer (under the
middle seat) from a 40x4 amplifier that fits quite nicely concealed
under the rear seat.  I bought the head unit new, and the amp used.
Most auto/stereo specialty stores will take the time to drop different
units into your dash just to see how they'll look and fit, and have used
goods from trade-ins that can save you ca$h.

..never without Uncle John's Band
