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 for the sub. Thinking the only way to save it 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! |

Port will need 6" clearance at both ends.. |
