    so you think that with that big of a box these subs will perform well,
    In the owners book to the subs, ALpine has the optimum ported box is gross internal 1.8 cubic feet and says net internal 1.3 cubic feet and a 24" long 12" by 1" vent, tuned 28Hz, 4.5db, 32hz whatever that means, lol im a lil new to building a custom box, jus wanting the get the most outta my subs

    yeah, their specs are a bit undersized. you can go double that on the type X and it'll sound much better. Altho i personally love the type x in a sealed box myself....about 2.5-3.0 cubes
