Gold Member Username: InsearchofbassPost Number: 9828 Registered: Jun-04 | I cant believe im helping design a box for these subs but you have 11 cubic feet gross by your dimensions and I cant find specs for these subs anywhere but id say give them 2 cubic feet each net (after sub and port displacement) tuned to 36 hz with 50 square inches of port (25 square inches per box)....they probably werent designed to play real low but it should work http://www.carstereo.com/help/Articles.cfm?id=31 |

Gold Member Username: InsearchofbassPost Number: 9830 Registered: Jun-04 | you could build the box and try them and if they dont sound right use the box you made for another brand of subs that work in that space |
