[QUOTE="Terrum, post: 8812966, member: 657229"] No worries man I just really hope you get better soon as it's never nice to have to deal with pain in general, let alone health-related pain. The design shows a 'Net Internal Volume' of 3.51 cubic feet so I'd assume that is fine. I would go for an aero port but I think all the builders I know would only be willing to use a slot port, plus if I were to build it myself I would definitely not be confident in making an aero port :ROFLMAO: As for power, that's on my to-do list as per another thread that I will soon update, where I am trying to find out the true amp power of my setup. The battery is 1850W so I'm hoping it's near enough that at least. The site does offer an option for 'Woofer Displacement' in cubic feet but on Sundown's site the displacement section was empty so I wasn't sure what to put there. So you suggest I put 0.2 cubic feet into the 'Woofer Displacement' field of the design? [B]IMPORTANT EDIT[/B]: Going by a quick Google search someone had the same problem where they couldn't find the displacement. [MEDIA=reddit]CarAV/comments/gtd1xy[/MEDIA] A response suggests 0.14 cubic feet (I assume per sub). Although I am curious how they got 'great lows but lacking punches'.
