SkiD87 Posted June 5, 2008 Report Share Posted June 5, 2008 Hi @ all i'm new on this site, but i thought i dont make one of those "hi im new here how are you!?" threads, so i just start this one and see if somebody can help me... This sub is currently in this enclosure tuned to 34 hz... the amp is an jbl bpx 2200.1 the problem is, with around, lets say 800-1000 watts it sounds very good and deep but above those wattages it seems like is it pushing more and more air but it is not getting much louder so is my port to big? enclosure to small? idk.... all that is in this car : http://tbn0.google.com/images?q=tbn:8uSIAS...rre/1574672.jpg this it not exactly mine but it is the same model i got the big three done, and my voltage drops from 14.7 to 13.4 full tilt on a stock 100 amp alt ps the sub is tc 3hp based tnx in advance Quote VW Passat 3C/B6 Variant Stock Vw Navigation System with Audio System Hi/Low Converter ( 3.sixty or something like that in the Future) JBL Bpx 2200.1 JBL Px 300.4 Dynaudio Front & Rear 2x Ground Zero Gzuw 15xii Link to comment Share on other sites More sharing options...
Elite Posted June 5, 2008 Report Share Posted June 5, 2008 (edited) Your box looks too small for a 15" sub. Try with a 90-100L box. And this sub is rated 2500w rms so get a better amp. Edited June 5, 2008 by Elite Quote Link to comment Share on other sites More sharing options...
Decaf Posted June 5, 2008 Report Share Posted June 5, 2008 sounds exactly like too small of enclosure, kinda reminds me of 2000+ sealed boxes, its loud no doubt but the sub moves so much for so little sound to be produced how many cuft and how many sqin port Quote Link to comment Share on other sites More sharing options...
SkiD87 Posted June 5, 2008 Author Report Share Posted June 5, 2008 I dont think the amp is the problem the box is around 4 cu ft and the port has 58.9001178002356 sqin that is what i got from my calculator after the math from cm² to sqin ^^ Quote VW Passat 3C/B6 Variant Stock Vw Navigation System with Audio System Hi/Low Converter ( 3.sixty or something like that in the Future) JBL Bpx 2200.1 JBL Px 300.4 Dynaudio Front & Rear 2x Ground Zero Gzuw 15xii Link to comment Share on other sites More sharing options...
