From what I can see, it is probably set pretty well as it is. Assuming you are using this amp only for subwoofers, here's what you've got right now.
the "LPF" switch appears to enable all three of those knobs. it stands for "Low Pass Filter" its purpose is to eliminate the high frequency (pitch) sounds from the signal, so your get cleaner bass. (since subs can't do high sounds anyway, they don't need to be there.)
This is on right now, so you're good.
"Filter" is probably the most important. That sets the cut off frequency. It is probably about right where it is, but that can be adjusted "on the fly" if you feel you want higher or lower pitch sounds to make their way through the sub. In my own experience, I keep this somewhere between 100-140. See the image I've attached for a great example of what instruments operate at what frequencies.
"Level" simply boosts the input voltage to the amplifier. If your subs aren't loud enough, this is what you would adjust to give it a boost. keep in mind that pushing it too hard will cause distortion. I wouldn't go any higher than "4"
"Low Boost" is basically a single channel Equalizer. it will give the extra low end a bit of a punch. Note where 40hz is on the chart below. Basically anything with electronic synthesizers will get a boost from this. (rap, hip-hop, electronica.)
