View Full Version : Port Help

04-07-2009, 06:50 PM
I am about to run 4 fi ssd 12's on a memphis mojo4kw. I am doing my box 8 cubes after all displacements. I am going to do flared aeros this time so I really need some help. I want to tune to 35htz but don't know what size aeros to get, how many, or how long so if someone could please help I would really be thankful

Any chance you have the box dimensions?

(3) 6 inch aeros will give you roughly 85 inches of port area. Make the ports 18.7 inches long to acheive a 35 hz tuning.

Are you sure? Last time I tried this I got a bunch of different answers. I guess I am just asking if you have dealt with aeros before

Check my build thread and yes Ive used aeros in about 5 different setups :cool:.. If you can get dimensions that would be great though.

precision ports has a website?


click on calculator. Don't forget to (re)calculate for port and sub displacements.
