Enclosure facing question?

[TC2k15x2]

In a trunk car that has non folding seats would it be best to face the subs and enclosure up, firing at the top? Its going to be 2 15's I have them and still havent built the box because I dont know which way to face them.

The trunk is not completely sealed the ski pass (Behind rear arm rest) will be open into the trunk and also air will be moving from the trunk into the cabin from the false speaker grills on the rear deck.

All help appreciated, thanks
