So I got a guy on here to build me a simple ported box. Dunno have many cubes it is, but I think its cubed to 32Hz. Im running 2 of these http://dls.se/en/car/prod.html?produkt=en_138 off a hifonics 1600W. Here is the box build http://www.caraudio.com/forum/showthread.php?t=361225
Its loud, but im wondering if a different box would be way louder. What do you think? A better box make a big difference?
