so within this next week i plan on getting an Fi Q 18 with the BP. Itll be powered by my elemental design nine.1 (and from reading through these forums, noone seems to like ED, but this is the amp im sticking to) and im guna be wiring the sub down to 1ohm. my enclosure is going to be in the ballpark of 4.5 cubes in my '01 extended cab ranger...but this time i want to go ported, and this WILL be my first ported box (and my 4th setup period) i want to do aero ports, but im still having a hard time trying to figure out how to get port dimensions and etc. and idk what to really tune it to either....i guess around 30hz or so and if it helps, i listen to rap (and country, but thats not what im focusing on lol) and i wanna hit some nice db's....not like im ever gunna get it metered, but i want to experience air pushing some body panels.. i used to have a sealed 19ov.2 and that thing HIT, and the 2 15" diamond d3's dont.....so i really want something that wont dissapoint me this time, and worse comes to worse, i can always plug the port if i dont like it...but i wanna try. so i guess my question is, can you guys figure out what sized port i need and how long. thanks a ton for helpin a newb to this forum out randy
