Mitchaford Posted October 14, 2015 Author Report Posted October 14, 2015 I just watched car audio fabs video on box design and how to get the port area but I'm stumped. I just dont know how the port is going to be:/ 2008 VW Jetta Team Fi 12 CT 4000.1 CT 125.4 PWX 6.5 80 PRS EB Flex 2/0 Second Skin ^^^ Build ^^^

Using max dimensions and I'm just stumped :/ I would like to use up all of that space, hopefully that is enough for 6.5 cubes This is going in a 08 Jetta trunk with sub facing the trunk. With those dimensions. your going to have to eat up some space. Maybe do double baffles all the way around. Those dimensions with even 1.5" thickness all the way around your at like 8.6 cubes net before bracing, woofer displacement and port being added. If you get down to 7 cubes net. 4" wide 17" height and port length about 18" your around 32 hz. Use a calculator and play around with it...

I was converting inches to feet Then multiplying them all together well that is how you figure out the wrong figure... lol "6.448" is the sqft using 3/4" just multiply all the inch figures and divide by 1728 you cant get anymore simplistic with the math
Mitchaford Posted October 18, 2015 Author Report Posted October 18, 2015 I got 7.9 . . . . What is the significance of 1728? 2008 VW Jetta Team Fi 12 CT 4000.1 CT 125.4 PWX 6.5 80 PRS EB Flex 2/0 Second Skin ^^^ Build ^^^
audiofanaticz Posted October 18, 2015 Report Posted October 18, 2015 I got 7.9 . . . . What is the significance of 1728? lol There are 1,728 cubic inches in 1 cubic foot. So dividing the total number of cubic inches by 1,728 gives you the actual cubic feet of the box.
