Evening all!
I have a Rockford P2D4-15 sub (the older 250w rms ones) in a sealed 3.5 cu ft box. When I built the box I (obviously) got a bit zealous with the size, and its about 2 cu/ft too big to run sealed. Manufacturer specs are 1.58 sealed and 2.66 ported so I'm not sure if I could even port it being its almost a cu/ft larger than their ported size but Im thinking the only way to save it the box is to port it. How many ports would you suggest doing? Where on the box? I'm in a CRV, so would I want sub up port back or another way? Thoughts on port length/diameter @ 37hrtz? Thanks!
