john253a Posted June 19, 2012 Report Share Posted June 19, 2012 the port per sq" is just a guide the port area is really has more to do with the cone and xmas of the sub then the size of the box, so with out knowing the car sub and power, it very hard to say, another thing the port wall surface area also helps alot, the lower the better Link to comment Share on other sites More sharing options...
