I need a design for a single 15" L7 for the backseat of a Nissan 720 kingcab. I was thinking a down firing slot, loaded box, ported up around 3.5^3 and I would like it tuned to about 30. Any help and ideas would really be appreciated.

I have like 24"dX36"wX20"h as I want to keep it below the window, The reason I would like to do the slot loaded is so it won't be seen, or touched, I have 4 kids and if they poke a finger or something through it I would be beside myself.

Is this the 08 version?
I know it will probably need more like 4-4.5cf and if it's the 07 it is best in about 5cf
Also how much power do you have for it?

i have a design for one, its tuned to 33hz but just fool with the porting and i could get it to 30hz. Its not shooting down but im sure I can tweak it. Its 3.5ft^3 with a 2.5" x 16.25" slot port. I know itll fit in that area. I built one for my truck it got pretty loud id have to say. I enjoyed it. Not the best pic but you get the idea:

this was before i cleaned up the hole and the box a good bit

I'm not sure what model it is. here is a pic I hope.

I could prob get another foot worth of space.

I have been driving my wifes car a 96 Gran Prix, and all I had in there was factory speakers and two Dynex (Best Buy store brand) 10" in a crappy 4th order, I just threw together, and it was pushed by an OS (early 90's ish) Crunch 50x4 that has the fronts outputs fried.Anything will sound better!

this is my plan

I haven't decide on port yet, I was thinking a 4" slot port that dropped down about 6" then went over about 24"ish then dropped another 6". But that is a lot of corners. Maybe just do a big areo

O k So with the box plan above I can get 6.5 cubic ft before speaker and port. I am thinking a 6 inch diameter port about a foot long should put me around 30hz. Any comments or criticisms would greatly be appreciated.
