and the guy @ the shop said that it would cost $100 for a ported box (he's building me the sealed for free), which is understandable b/c it takes an additional hour, and another sheet of wood. i told him to build a sealed, b/c im broke now that ive paid for the subs, amp, wiring etc etc. but im sure it will be fine cause i will get a lot of reflection off my back glass anyways, even though i would PREFER ported but...**** happens.
