LP filter is more personal, i believe mine is at 85-90 hz. Gain(input sensitivity) should be a low as possible to achieve the best sound with the keast distortion. Mine is just above half. Bass Boost should be to a minimum IMO.

On the amp - Set the "Bass Boost" to 0 db and turn the input sensitivity all the way down. Then set the Low Pass Filter around 80 hz.
The goal is to match your input sensitivity to the output voltage of your headunit. Start with your head unit at its lowest volume and turn it up until you hear distortion and then back off a tad. Now with your head unit putting out its max clean voltage, turn the input sensitivity on your amp up until you get to the loudest your system will play without distortion, or the loudest you ever care to listen.
Next adjust your EQ on your headunit to get things sounding more appealing to your ear. Then you can tune the LPF slightly, if higher notes are desired. Best results are achieved at 80 hz and below.
When you have everything the way you like it, you can use the Bass Boost on the amp as a last resort to add a bit more thump. It is best to use sparingly because it doesn't give you the control of an EQ. Bass Boost usually amplifies around 50hz which can make some sounds thump to loud, and others to soft.
Hope this helps, good luck!
Edit: Just looked that amp up, you might be better off wiring your subs in series and bridging your amp. Theres really no benefit to having your subs playing 2 separate channels.

yea i got each sub wired to 2 ohms and hooked to seperate channels so it won't overheat... and it pushes 250 rms to each channel or i could get 500 split to the 2 subs if i bridged it so its pretty much the same
