it was the box, and sub. 20 is too low for a bandpass box, and i dont think that sub can drop to 20hrtz safely

You were probably listening to distortion. 20Hz bass note should be something that will not be heard, but felt. More like a "wind" vibration.
If you ever look at a sub that can actually produce 20Hz note, you'd notice that it's movement is very rapid while producing very low audible bass. The notes that your ear picks up are usually 30Hz and above. Anything below that just shakes and rattles windows and chests.
