ok right now i got a 3 in port and im getting allot of port noise .i was told this might happen but didn't listen o well live and learn i guess .according to the 12volt i need a 22 inch 4 inch port but my box is only about 13 inches deep so im thinking i need a 90 elbow bend so how dose that figure in to the over all port length and if i go flared how dose that calculate in so if any body knows a sight that has a flared port calculator let me know
