I am making a custom box for 2 10inch Kicker CRV dual voice coil woofers. My inside dimensions r 11.5 x 22.5 x 22.5. I have not separated the two chambers because I only have one side of the box available for porting. I would like to know what the volume of the port should b? I have used a formula and came up with the volume, but it does not seem right. And I am using a slotted port.

PORT Size Calculations and Formulas for WOOFER and Subwoofer BOXES (http://www.carstereo.com/help/Articles.cfm?id=31)

That will give you the length you need. Determining the actual length of each port piece is a bit trickier. For that you'll have to do some searching.

Port volume in cubic feet = (L x W x H) / 1728. Your total internal volume should be the expected net volume (Example: 4 cubes) plus port volume and subwoofer displacement.
