TheBetterMethod Posted January 9, 2011 Report Share Posted January 9, 2011 You can use an online box calculator and port calculator to calculate box volume and tuning length for the ports. You should use 3-4 4" ports in a box that size (4 cubes). General rule is 12-16 square inches or port area per cubic foot of box. Each 4" port has about 12.5 square inches of area. 2005 Subaru Outback Wagon Pioneer 9400BH Fi Q 15, SAZ1500dV3 The first build>>> http://www.stevemead...-outback-build/ 140.9 @ 36hz Sealed on dash!

I can get you something set up with a box calculator give me a few. I'm using aeroports for the first time too in my box I'm building currently.

bumonskateboard6 Posted January 10, 2011 Report Share Posted January 10, 2011 I'm not having any luck if you have to do subs up port back there just isn't enough depth with 14" to get enough port area with an aero port and tuned as low as you want it...if you want to do some port bending it can be done but won't be simple and this is still on the low side of port area maybe someone with some more aero experience can chime in: Current Systems: 2011 BMW 335i Hertz HDP1 DC LVL3 12" Full Carbon Fiber 2002 Acura TlKenwood DNX9980HD2 DCLVL4 12" Subs with LVL5 Parts D.7 CoilsDC 3.5kHertz HSK-165 up front HCX-165 RearHertz HDP4 AmpDC Power Engineering 260 Amp AltBig 3 and amp powered with KNU 1/0XS Power D2400 Up Front i pulled out my dick in class many of times and had it shown. get over it bitch...stupid open legged hairy beavered bitch... going over rms = smaller box, under rms = bigger box...
