DatDude619 Posted July 8, 2014 Report Posted July 8, 2014 2 RF p3 d4 15's .249 displacement each 45w 15h 21d (exterior) (3/4 MDF) total volume 6cu after woofer displacement Splitting into 2 chambers to ease bracing so each chamber is 3cu after woofer displacement. What size and length aero ports? What would the ports displacement be? Looking to use this to make the port: http://m.lowes.com/product?langId=-1&storeId=10702&catalogId=10051&productId=3133049&store=2370&view=detail&nValue=SEARCH Also fired up port back best solution for this box in a 02 mountaineer?

DatDude619 Posted July 8, 2014 Author Report Posted July 8, 2014 So how many ports to get the port space using the 4 X 8 aero ports
Krakin Posted July 9, 2014 Report Posted July 9, 2014 (4) 4" ports will get the required port area for each sub. You need to take into account the displacement of the ports when trying to get the right length. I can tell you for sure that 8" long ports will not work.
