ok thinking slot port right now. now i have never done a slot port but how hard could it be. o well anyways i have outer deminisions of 36/16/27 which comes to a total internal volume of 7.38^ft3. what i want is about 3 cubes per sub after the port displacement and sub displacement. i was thinking something tuned around 27 or so. i think this is still a low enough tuning that i won't need a ssf. what ever size of port u guys think would work best then that is what i will probaly do. thank you in advance. i'm lost without u box geniuses.
