Hello. I am new here and looking for an answer to an easy question. I have a 2002 Civic and I am looking at a Q Logic Custom sub box. First, does anyone have any experience with those units. Second, the volume of the Q Logic enclosure is 0.65 cu. ft. The Fi Q I am looking at calls for 0.2-0.6 cu. ft. of volume, but it has a 0.12 cu. ft. displacement. Does this mean the Q Logic would work? The way I am calculating it is that 0.65-0.12=0.53 cu. ft. volume after installation. Thank you in advance for the help. Nick
