The KICKER SX amplifier monitors and prevents any low pass
crossover point from being any closer than 1/3 octave from the
high pass crossover point. If you cannot set the low pass
crossover where you want then check the
HPF indicator and see
if it is flashing. If it is then you need to go to the HI-PASS menu
and raise the high pass crossover point.
This is done as a safety precaution to prevent a notch filter
condition.
