all right i came up with this in bbp and i would like someone else to double check it. i want a 4 cube box net, tuned to 35 hz. using 2 4" areo ports. i did not factor in driver displacement yet, since bbp won't let me for some reason :confused: i will do that but for now, my internal dimensions are 34.5" by 15.5" by 13.5" with 2 4" areo ports that are 11.25" long. when i run the areo's on another calculator, i come up with they need to be 11.75" long. also is it a good idea or not to run the areo ports through the 6x9 holes in my rear deck and have the sub fire towards the rear?

For driver displacment, click "Interior" then next to driver mounting, hit lock and enter the value manually...

Box = 4.02ft^3
Ports = 11" long
Tuned to 34.8hz - same thing as 35;)

Driver displacement will decrease net volume and increase tunning.

Good question.

Not a good idea....baffle seperation means that the ports won't work as they are supposed to ....even with rear firing ports, the faceplate should always be in the same airspace (but im just a noob...so take that with a grain of salt).

That box is 4 cubes net before the port(after a decent sized sub). Don't think the ports will take up that much, not sure how much it will effect tunning either.
What you running? Gotta be a beast if you want even more output that your previous setups.
Oh and go with a single 7" port :)

figured i'd give an sx a try. if it doesn't work out these people gobble up re on this forum, like a virgin picking up a hooker
