long shot question about supercrew box

I realize im usually not so helpfull with my JL hating, but it stems from years of other pro audio boards that stress the same thing, so its in my blood

but anyway, getting ready to start on the audio upgrades

my main question is, will my saz-1500d which is 17" x 9" be able to fit vertically in the middle of the supercrewsound dual 10" box and still be able to fold the seats back?

To my understanding the height of the box is 14.5" which leaves 2.5" above the box, will the seat still fold back? and if not, is there enough room to angle the amp forward a bit or something?

what are you guys doing with larger amps?

also hows the stock (towing package) alternator holding up to 2k+ watts?
