Minigopherv25 Posted May 16, 2012 Report Posted May 16, 2012 I have a Fierce Audio Dual 12" Sealed PS212.1 (1.15 cubic feet per chamber) with 2 Rochford Fosgate P2D212 (rms 250). I wanna port that box, but I want to still feel it as much as I do know but I want it louder. If I can haha I also have an Alpine Type R SWR-1243 in a 1.0 cubic feet box. I wanna port that but I want to still feel it as good as I do know. I just wanna know if I can do that and what frequency to tune it at and where to put the port. Help please!!! Thank you!!
Crandis16 Posted May 16, 2012 Report Posted May 16, 2012 A lot of it really depends on what kind of vehicle that you have. A lot of people suggest 34Hz. I personally am going for 35Hz and I am undecided on if I want to seal off my trunk and have the port firing into my car or have it mounted in the back of the trunk firing towards a corner. It all depends a lot on how you position your box. My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL

Guest Posted May 16, 2012 Report Posted May 16, 2012 dont bother porting an already sealed prefab box. best bet is to build an entirely new one.
audio1der Posted May 18, 2012 Report Posted May 18, 2012 dont bother porting an already sealed prefab box. best bet is to build an entirely new one. +1 Not trying to be difficult (or a prick) but those boxes are too small to become ported enclosures for those subs. Not to mention the volume f the port which needs to be accounted for... If you do figure out something/build a new box, I prefer a 36Hz tune for a daily driver. That's personal preference- find out what guys with similar car to yours tune to and see if you like the way it sounds.
