I need some help with a design and box. I have a 04 Ford f150 will be running 2 tantric hd 15's on a saz 2500v2. The space I have is 56 x 28 x 30(up to window). I have a 3 yr. old I would like to keep a seat back there. So what I came up with is taking out back seat making 2 separate boxes with jump seat in the middle. Max for each would be 18 wide 28 front to back 30 high. I can go higher but would like to stay around window line but not a must. I was thinking sub forward port up. Any help would be appreciated and I am not dead set on this, very open minded. Thanks.
