I also have a Bazooka tube under the left side of the rear seat.  It rests
on a piece of foam and is strapped in with typical black pull straps....can
be removed at any time.

Sounds great with my Sony head unit, CD player, amp and ADS speakers.

Its not a hip-hop ...shake store windows type woofer...but sounds great
with the jazz I like to listen to.
