ok, im about ready to order 2 MTX Thunder8000 10" subs, a RF amp (1001bd), and a 1 farad cap. i measured the boxes for the truck (standard cab) and it comes out to, roughly, 1.5 ft^3. the recommended ported box size is 1-2 ft^3, and sealed is .5-1 ft^3. I want spl, not sq, and i regularly crank metal up VERY loud. Also, its one big box, not two seperate ones, so would that affect porting, anything like that?
