4 4" or 2 6" aero's would work nicely. You even have the room to run them external. If you want to go with a slot port, I'd do at least 70 sq in. My truck LOVES port area.

if you end up running aero ports internal be sure to keep them at least 4-5 inches away from all walls

Most of the trucks I've seen are louder with subs forward. Then again, it can depend on meter placement and other factors. I typically meter at the headrest, and I'm louder with the subs forward. But, I do pretty much the same score in the kick whether the subs are forward or up.

You can make your own or buy them off of partsexpress.com

Subs up is a full dB quieter than subs forward.

I did get a little excessive with the exclamation marks A dB is quite a big difference, especially when you get into the 150's. People would get a lot more sound out of their cars if they spent more time learning their car.

There's a tuning calculator on psp-inc.com

The calculator will tell you the length that each aero must be. The more ports that you add, the longer they must be. If you don't like the way that the tuning sounds, you could always simply change the port length Yes, the flares do help.

thx so i did the calculator put everything in for 4 4" aeros it gave me 42.50 overall length... so i divide that by 4 correct to give me 10.650" there for each flared port will be that length. so with the length of my box i can port them to the sides but not down will that affect n e thing?

here is a pic of the box
