dkahns51 Posted April 16, 2011 Report Share Posted April 16, 2011 Does the sealed part of the box have to meet the required sealed space for the sub? And then Does the ported part have to be the required ported space for the sub? For example.. DC 15inch Level 4. Sealed 2.75 Ported 3.25. If i were to do 2 of them in a 4th order would i have to have the sealed part 5.5 and the ported part 6.5 or is that not how a 4th order works? Ive been messing with Bass Box 6 Pro and i cant figure it out.. any idea or help would be appreciated. If anyone wants to setup a box for me if they are bored that would be cool lol. . Measurements of my hatchback area.. Front Height 26" Back Height 20" Width 37" Top Depth 6" Bottom Depth 23" **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
dkahns51 Posted April 16, 2011 Author Report Share Posted April 16, 2011 Anyone have any ideas on how the Cubic feet should be for these type of boxxes? **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
speedball1978 Posted April 16, 2011 Report Share Posted April 16, 2011 lol, don't worry, a few guys that knows 4th orders will help you out but from the threads i've read, its a 3 to 1 ration ported/sealed.. so if your sealed area was 1 cu ft, then your ported area is going to be 3 cu ft...

Ahh good stuff, thanks. So with that said i should probably match the Recommended sealed area for the sub that DC requires? **Clicky>>My 2009 Subaru Impreza Outback Sport Buildlog<<Clicky** I'm messing up 98% of the time Link to comment Share on other sites More sharing options...
speedball1978 Posted April 16, 2011 Report Share Posted April 16, 2011 honestly i can't answer that question because i haven't gotten that far, i've seen some people go with .76 on the sealed side.. read up some articles about 4th orders..
