Suggestions for wall in explorer

[Eric]

vehicle is a 97 explorer sport 2D.  I have 2 L715's now, but I'm thinking about walling it off.  I'm wanting to do 6 L715's in a common chamber ported box.  Each sub will have a hifonics Bxi 2006D to it.  Any suggestions on sub volume and port area?  I know things change when you put multiple subs in the same chamber?  Just wondered if anyone had any suggestions or comments (good or bad) that might help me out!  Thanks,

Eric

6 L7s is gonna be crazy loud...Better get a good electrical system to back that up :^

That's what I'm hoping for    Electrical will be good if it all gets done

Oh yeah....Walls are for pussies (j/k)

I've plotted some specs into my program for the sub box (assuming it gives me an accurate representation of 6 in the same box).  What kind of response should I get if I tune it to say, 28-30 hz?  Being in a wall, I'm not sure what that will actually tune it to once it's all in there.  Any ideas?
