Sundown zv4 15 rev2 d2 in a 4th order help??       I'm trying to figure out what sqft I should go with on the ported and sealed side and how many sqin's my port should be and what to tune it to for a good musical daily box?? I've been told to do a 3:1 1.75sealed and 5.25 on ported tuned to 40hz then I was told to go with 1.5sealed and 4.5ported tuned to 32hz by 2 different people?? The tuning seems completely different from each other and I would just like to get it right the first time around or at least close. Any info would be greatly appreciated, thanks!!
