sub box

hey guys, i have a dual 2ohm alpine type R 15" sub and at the moment its in a ported box which i dont think is the right size so im looking at building a different box, its going into a suzuki baleno hatchback im looking to build a ported box tuned to around 30-34hz i hear thats a good number what dimensions and what type of port would sound best with this sub setup ?

A friend of mine has that sub rockin louder than anyone else I've heard or seen. His box has a gross of 4.5 ft3, 1.44 ft3 of vent space, which is about 50si. Your vehicle probably wont allow for that so post the dimensions of the space you are going to allocate for the enclosure. The amp type can have a effect on the performance so that may be a good thing to mention too. "Best Sound" is opinion based only. Do you want to hear or feel you sub? J. Reed probably will have the numbers you need based off the info gathered.This is what I do for FUN!

im more looking to feel the bass, ive got a fusion am2000d (the 1000watt rms at 1ohm amp) and the box i have at the moment is around 3.56 cubic feet from memory and its about as big as will fit in my car.
