OK Im kind off a noob so please bear with me. Im planning on getting these subs...
Amazon.com: Rockford Fosgate P2D4-12 Punch P2 DVC 4 Ohm 12-Inch 400 Watts RMS 800 Watts Peak Subwoofer: Car Electronics (http://www.amazon.com/Rockford-Fosgate-P2D4-12-12-Inch-Subwoofer/dp/B004UFHXIS/ref=cm_cr_pr_product_top)
And Im planning on making a box for them. Everybody/sub box calculators keep telling me to make a sealed box. Why is that?

I just want to know why having a sealed box is better than a ported.

The sub's specs determine the kind of box it needs.

p2's will do way better in a ported box. Give em' around 1.75-2.00 cubes a piece, tune it around 32-34 and you'll be all good. You won't get the output you're looking for with a sealed box. Trust me... By the way, if you want throw another 15 bucks a speaker these will own the p2's in every category: http://store.soundsolutionsaudio.com/products/sundown-audio-e12-subwoofer-400w-e-series.html
