fecupe2001 Posted June 4, 2013 Report Posted June 4, 2013 have you tried what works better? im talking about port and subs direction, subs up/port up always work great on hatchbacks, i would start with maybe 3.2 cubic feet and a 8" aeroport on the middle of the 2 subs, do you have a meter to work with and test? without it, you are blind! I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.
