Hatchback box design

[y2kbugger 10+ year member]

how should designing a ported box for a hatchback be approached

max dimensions:

35" wide

15.5" tall

deep enough

2 type Rs

low tuning

I can flare the port, so it can be smaller for less peakyness

there is a thin piece of plastic/fiberglass covering the "trunk" that I will be leaving in place, don't want my gear being seen as i'll be in on a college campus.

Its a second gen Ford probe

port and speaking directions, i mean i think it can only back or else it'd be hitting right on the plastic piece.

and why is it better to face subs away from you?

SUbs away from you is so the bass can reflect off the trunk lid and be louder.

I am not sure if this is true, but it would seem it works better sub/port back because it allows more distance for the sound wave to build, I have noticed in most vehicles, actually, the farther back you can get the port/subs the lower and cleaner it sounds. This has to be why, but I have no data to show it for sure other than testing in vehicles I have personally done....
