right now im running them in a small sealed box that my buddy let me have but i feel im not giving them what they deserve so i want to design and build a new box. so far from messing around on the re calc i've come up with approx. 6 cuft tuned to 29 hz, i was thinking this would be good for lows and it would help since my amp doesnt have ssf. Any opinions on the enclosure only would be nice i know i could get better subs and a better amp and etc etc but im working on getting the best from what i have right now with the least amount of money possible. Also does anyone reccomend much if any bracing for such low power? Approx. 3-400 rms.
