I would not filter the main speaker as this negatively affects the whole music signal. The 30.1 goes only down to 50Hz. Set SAM to 0% and the lowpass for the sub to something between 40 and 60 Hz.
SAM will not effect the sub as Jean-Marie already said. Try if SAM set to 0% is doing good things at all, otherwise leave it off.
