NU B Q's.

Hello all from John, a newbie from Melbourne, Australia, doing my first SW install.
I plan to make a 10 litre/0.35 cubic foot subwoofer enclosure per the Polk specs for my db840DVC and this will go in the trunk of my '98 Mitsubishi Diamante.
Here are my dumb questions:
(A) Does it matter in terms of sound dispersion or percieved volume which way the sub speaker box is pointed- ie. side, front facing or rearwards?
Or for that matter, where in the trunk the sub is placed?
The 2 candidate positions in my car, a sedan, are:
(1) As far forward as poss. and thus close to the rear seat back (in fact potentially mounted on the rear seat back, if not the floor of the trunk), or
(2) At the rear of the trunk and to one side behind a wheel well, but up off the floor, hung on brackets. I need the floor space for my v. long bass case, among other things.
I'm asking this because, unlike the situation of passengers hearing door mounted or rear deck speakers, with a sub in an enclosure sitting in the trunk there is of course a barrier to the subs sound entering the passenger compartment and thus the listeners ears, formed by the rear deck/parcel shelf and the back of the rear seat. And these barriers being formed by a thin sheet of steel plus some upholstery, surely some muffling of sound originating in the trunk must occur. At least, you would think so.
Some sundry related Q.'s
(B) Are the frequencies subs produce sufficiently deep that these barriers don't matter much?...or is it the case that the whole trunk compartment acts as a speaker enclosure and the vibrations are felt in the passenger compartment?
(C) If the trunk is filled with luggage, is that going to muffle the subs output as heard inside the passenger compartment?
Over to you. Hope these Q.'s aren't too dumb to bother with answering.
Thanks, John

Hello John. Welcome to club Polk. I recommend you re-post your question in the Car section located at the bottom of the main page for this forum.I refuse to argue with idiots, because people can't tell the DIFFERENCE!
