Should be on LPF and at or around 80 Hz. What ohm load are you going to be running these to the amp at? Do the Square root of the RMS you will be putting tothe subs divided by the ohm load you're running at. SQRT (rms/load). That answer is your voltage the amp should be putting out to your subs.

Use this equation to figure out voltage power output:
- Take the RMS wattage per channel and multiply by speaker(s) ohm load
- Now take that number and push the square root button on the calculator
Example: 50 Watts RMS x 4ohm load = 200, square root = 14.142135
So the voltage reading for our example on the digital multi-meter should be 14.1

for settings on the amp try starting with this:

LPF 60Hz
Phase 0
Bass Boost 0
Q (slope) 18dB
sub/infra-sonic filter set to tuned port frequency of sub box if ported, set to off or lowest setting if sealed.

see what you think. then maybe try 50Hz for LPF and see if its better or worse
