Posted May 5, 200916 yr I have a Fi Q 15" subwoofer in a 4 cu. foot ported box tuned at 30 Hz.I was wondering what range of notes it should be able to hit accurately and safely so i can tune it on my amp?The amp im running is a Hifonics 1606D turned down to around 1000 watts Edited May 5, 200916 yr by Joeys91
May 5, 200916 yr not sure about the range, but the gain doesnt limit the amount of power the amp can produce, fyi
May 5, 200916 yr You'll want to set the subsonic around 25 hz and the lowpass somewhere between 60 and 80 hz, depending on how low your interior speakers can play effectively.
