i'm not into SPL, but im building a ported box(slot port) for a friend.. just curious how do you tune a box? also what about if the amp can only produce to 50 hz or maybe 40hz, can you still do it lower? i already installed winisd, but i just dont have any clue how to use it.. any help would be appreciated..
