I'll be getting 2 Fi Qs this summer and right now I planned out a box that has 1.3cuft net for each sub. Would I notice much of a difference if I upped that to 1.4 or 1.5 (1.5 being the upper limit of the recommendations)?
Also the opposite. If it wouldn't make much of a difference it'd be nice to make it a bit smaller (maybe 1.2 each) and save a good amount of trunk space.
