I promise to hold back on the marine-life jokes.

There is a steel panel in the middle of the rear seat where the ski-bag would go.
Its not structural, and its held in with four little spot welds. It's there to
keep the noise level down. You can literally remove it with a good kick, and it
will give you a pass-through roughly equivalent to the cone area of a 15" woofer.
This should be big enough for the bass to swim through. (OK, so i lied. Impeach
me.)
