port placement & box advice 15XXX
I have 15" RE XXX in my Focus ZX-3. 2400rms to it. I am going to build a new box for it. It will be 35" wide up to 20" tall and up to 20" deep. I have 3 4" aeroports. And a lot of questions. Car is daily driver, non competition. Plan to tune to 33hz, good freq and fs of driver. I plan on, but don't have to, face ports and sub up (don't want to beat the hatch open) . I have termpro and can figure fb and vb, and have built a lot of boxes but now I have a few questions.
slot port (if slot how big? 5x12?) vs 3 4" aero ports
Should the port(s) be close to the sub? Or sub on one side, ports on other?
What size box? 4ft? 5ft? could be 6ft. how much is too much when ported?
