I have a image dynamics id 12 v4 250 rms i want to put it in a 4.50 cubic feet port tuned to 20.5 hz for just home theater use but i know this is a large box for it so power handling should go down. I have linux so i cant use windows programs to figure this out. I would appreciate help figuring this out. I dont want to damage the sub and i have a 150 watt plate amp.

(please run this on winisd for me someone)

I got wine to work on linux so i ran winisd and got 3.75 net at 22.4 hz with a 4 inch precision port which should be enough with the flare for port velocity; especially since ill only be using a 150 watt plate amp.
