That's plenty of room for 18s. Plenty of port area is capable with this size and how does 34 hertz sound. Is that low enough?

Its not plenty of room for 18's .... you need to step it over the wheel wells.. doing this will get you around 10.5-12 cubes. Its a very tight squeeze but it can be done. I have my tuned to 27Hz .. its low but takes my net to ~10.4 with 135 sq in of port. Try to aim around 14-16 sq in per foot.

origional dimensions given were 39x25x30. I went 38x25x28 into 2 different box design programs I use. 13.15 is gross on those dimensions. With subs up and port up I can get 150.00 sq in of port which is 14.10sq in per cubic foot. final tuning on this was 34.94 hertz and net volume after port displacement was 10.64 cubes. So... 5.32 cubes per AQ 18 is plenty of airspace with an adequately efficient port. ?'s
