Is this generally louder?

Better SQ?

Also how much port area should I run (18"DR)

from test, yes the sub up/port back is loudest.

18" DR = IA Death Row?

works great for me in the windstar!

i since move the port facing inside and the subs up (was short on wires)

and it doesnt sound as great...there is far less rattling from the hatch but

weaker bass

110 square inches or so; or 2 6" areo ports.

wouldn't 2 6" aeros be like 60 square inches

areo ports are more efficient at moving air than rectangular ports.

They can use less area and (therefore) less depth to achieve the

same Mach rating (whistle/port noise factor) and tuning.

Oh. Ok.

What about corner loading the port(s)?

You could put the areo ports, if you went that way; low, rear firing and equi-centered (not right next to each other in the middle). You would also want to give the port 6-8" of distance between the box and the rear hatch of the SUV. Basically, your loading off the back wall, then up along the roof line primarily, and secondarily into the corners and back along the sides.

In a previous setup I gained 1.5db subs up port back over subs and port back. In my current setup I gained 0.5db sub up ports to the driver's side over sub up ports back. This doesn't work in all circumstances though. Subs up and ports back is a good safe route. I agree that two 6" ports are perfect for that sub.

No problem. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

6 cubes is not a huge box, so you need to look into whether

it is better to build the box with a gap between the side walls

for the wave to come back forward, or if you want to force most

of it up by building the box exactly wide enough to fit in the back.

I'm actually not sure which is better.
