Custom Box Dimensions
I took some measurements off my truck today to see what's the biggest box I can fit behind my drivers seat, with the x-cab jumpseat folded up.
The dimensions are:
15W x 16D(1) x 13D(2) x 15H
Based on y'alls past expierences, what are my options with a box this size??

inside a relatively small interior like that of a truck you will want
to use a slightly larger enclosure for your woofer(s) if possible
The woofers tend to sound real 'punchy' if not
also you some acoustic damping inside the box
I would recommend a sealed enclosore box with a single 12"
woofer
With the dimensions you took you will get about a 1.45cu ft.
enclosure-subtract woofer displacement .110cu ft.==1.34cu.ft
Find the woofer you plan on using and look up the recommended
enclosure volume in cu ft.--with a sealed enclosure you can give or
take about 10% of the volume --In your case I would go with the 0-10% greater than recommended which will lower your resonant
Frequency and lose some of the punchy sound--deeper bass
I just built a sealed enclosure for my extend cab f250
for a 12" woofer--it called for 1.0 cu ft.---I built the box at
16"H--16"W--10"TD--13"BD with woofer this yielded 1.10 cu ft.
sounds excellent --fits like a glove
Take your dimensions and subtract about an inch in the depth
and you will be in the ballpark for a 12" woofer
also note if you plan on sealed box--they generally sound better
firing up or to the rear of the xtend cab
post if you need more info

Just make sure when calculating dimensions to pay attention to inside dimensions and outside dimensions. It's very easy to make a box 1.5 inches to big. I did it on my first box and nox I have a box in my Explorer that fits perfect with not even 1/4" to spare any where.
