 I just toss the Bazooka under the rear seat. You have to fold the bed out
and take it in and out from the back, but its easy to do. I didn't even
strap it in as it stays in there, only two wires for the speaker itself. I
installed a 100 watt amp above the glove box to the bottom of the dash as
there is quite a bit of room in there. I use an on off switch for the amp
and an low level alpine gain control to set the gain on the sub from a tiny
knob on the dash. This way when a certain song comes on like some Lynard
Skynard ( http://www.magic-tab.com/a/Sweet_home_alabama/index.php) I  can
turn on the sub amp and crank up or down the sub to where I like it.

IT WILL ROCK YOUR VANAGON BABY! BELIEVE ME!

The only problem is my rearview mirrors JIGGGGGGGGGGLE
WHEEEEEEEEENNNNNN  THEEEEEEEEE BASSSSSSS ISSSSSS PLAYYYYYYYINNNNNNN.
