you need more port area if you are getting port noise
you have 6.28" of port which is like 3" per foot

  1. Turn off whatever bass boosts you are using.
  2. Turn up the subsonic filter and it will reduce the frequencies which are too low for your box.
  3. Larger ports.

I mean you have way to little port area for your box, making them longer makes your box tuned lower but they will still be over flowed and make noise
