With only one amp receiving signal from your head unit, play your favorite type of music at about 75% volume with the LPF filter on your amp set as high as it will go. Slowly turn the dial from high to low until you stop hearing all the high frequencies through your subwoofers.
What should LPF be set at?
As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speakers lowest frequency response. For example, your speakers frequency response goes down to 43Hz.

Thus, the recommended settings are a HPF (5000 Hz) for the front tweeters, a HPF (80 Hz) for front midrange, a HPF (80 Hz) for rear speakers and 12 dB or 24dB slope. If rear speakers (passive) are added to this system, the settings will change a little bit.
