Hello, I am building a box for two Kicker 8L7's under the rear seat of a '98 chevy full size pickup. My question is this. How do I know how long to make the port? for example when I plug all the specs (1cu.ft. tuned to 33hz) into winlsd it tells me a 4" dia port 29.5" long will do the trick. am I reading this right? I guess I don't understand 100% how WinLSD works. Could someone please help me understand what I need to do to get this done?
Because of the size of the drivers and depth of the box I can't wrap a slot port around the inside of the box.
I guess what I realy need to know is what the "Vent length" box is used for

Yep, that sounds about right. I got 28 inches with WinISD Pro. I guess you're using the beta version.

alright, but there arent any sides of the box that are even close to 29" long. when I say I want two ports it says vent "length" should be 58" long. is a vented box not possible in the space alowed?
I'm not even 100% what size the box will be yet but iw will be aprox. 20.5" X 10.5" X 8"
