CleanSierra Posted August 12, 2013 Report Share Posted August 12, 2013 Oh, you never told your port length either, that is helpful info. As far as the port width changing, yes, that could ABSOLUTELY be your issue with the change in width. Im not the one you want to try to troll. Just a fyi for you.

stroupe79 Posted August 12, 2013 Report Share Posted August 12, 2013 I would personally set subsonic no lower than 5 below tuning...tune to 29-30hz and you should be able to play 20s pretty well, not sure about actual 20hz but in the 20s... I would like to mention that other than Decaf your not really going to have very much music that's actually in the 20s anyways, so tuning to low 30s is a nice area to start I would also do between 12-16 inches of port per foot...I personally run 12ippf @35hz with subsonic @30hz...and wish I would have tuned lower with a bit more ppf, but I don't listen to anything but Decaf/Rap/HipHop... http://www.stevemead...cherokee-build/ 2005 Jeep Grand Cherokee Alpine CDE-hd148bt Alpine PKG-RSE2 PRV Audio (4) 6MB200 front/rear doors PRV Audio (4) TW350Ti dash/rear doors Kicker KX350.4 Obsidian Audio (1) 18 D4 v2 revamp (2) Stereo Integrity HT 18d2DC Audio 1.2k5.25ft^3 tuned @34hz revamp Infinite Baffle Cpillar AudioTechnix 60mil deadenerKnuKonceptz & SkyHigh wire (complete setup) Link to comment Share on other sites More sharing options...
DCdakota Posted August 12, 2013 Author Report Share Posted August 12, 2013 I do listen to decaf, and I feel like running to 29-30Hz would be pointless with a fs of 30 does that sound right Link to comment Share on other sites More sharing options...
