so brandon by looking at your calculator looks like you have the port positioned vertically while say if i do up fire(as in external box specs are still 33" depth, 23.5" height, and 45" width with subs on the top on the box. how & should i do that?? and you honestly think ill need more batteries? like how many would you estimate? cause im running all the amps at 2ohms which in theory it wouldnt drain or suck as much current at one time..

OH and i forgot to say ill be using 1" mdf all way around with quite some bracing inside.
