set your lpf at 63 and your sub sonic to 20 Hz. and check the settings on the amp and make sure the xover isnt turned off

At 60hz you shouldnt be hearing vocals. Does your HU have an LPF? Might want to use that instead of the amp's. If not, try lowering the LPF on the amp a bit more and see if it goes away. If not, then it sounds like it's inaccurate/faulty.
