Guest Posted May 23, 2008 Report Posted May 23, 2008 I put in various subs in the program, made a custom file for each, and the specs were near perfect to paper specs. i put in the rms rating for the power, ohm measure. and the damn thing says that 2 12's will only hit 120db, 4 12's is like 125. do any of you have this problem? its kind of annoying
banginAltima Posted May 23, 2008 Report Posted May 23, 2008 That part of WinISD never works right. I believe those number are with the box out in the open, like its just setting on the ground. WinISD is really only good for finding port length at a given freq. If you build it, db's will come... NSPL World Record Holder Trunk 0-1800 watts---147.9 with 1722 clamped watts @ 40Hz(9-20-09).

WinISD is really only good for finding port length at a given freq. x2 I've never used it for anything else since in-car response is most likely going to be completely different anyways.
