well i couldnt find a tread that tells me how to get rid of it. im running a jbl gt5? in a 1.6 box, the box has 2 tube ports 2in by 7 inch. im getting what i think is port noise( sounds almost like a whistle) when deep bass notes hit. how can i get rid of said noise?

  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.

jbl recommended a 4 inch port, so i figured 2 2s would be similar. so should i just lenghten my ports?

i see. and shat......


but in theory i could add 2 more ports right? or would that be too much? ACTUALLY SHIT JUST CHECKED each of the ports would have to be about 20 inches lol
