4 DD 1508's Box design help :D

Like the title says, got 4 of these going in my truck (2001 Nissan frontier Ext. cab) and I'm gonna do a downfire design behind the seats and need to to know which would be the best way to place the port. I've been doing port up the last few installs with success but I heard a few people say port forward and I was thinking 2 ports out each side facing the side walls.

Anyways, any help would be appreciated. Thanks in advance //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Here's a pic of how the back part looks empty, the box would be downfiring on that, hope this helps.

Port too? How far away should I make it? Like 4" for loading?

Man that is a nice design, when I get an SUV in a year or so I'll have to come back and take a look at this.

Oh ok cool. So just multiply the two measurements and divide it in half? That would seem a little big.. Or do I just add the two measurements?
