    I assume the OP is asking what crossover frequency to use.
    Again as willow said 80hz usually works great.

    At times we have tried 100 and even 120 hz, and depending on location of sub, it can draw attention to itself, but if centered or like we do, 2 separate subs, can be a huge aid in reducing the load on a lower powered AVR and help clarity of smaller Left and right speakers, by removing the bass burden even more.

    Levels are usually set by the AVRs set up program, but can be fine tuned manually.

    I think you are referring to the knob on the back of the sub, correct?

    This is assuming you are using the LFE connection with a sub cable (there are different ways to connect a sub and you didn't mention how yours is connected). Disable the crossover on your sub. If your sub does not have a dedicated switch to disable the crossover, turn the setting all the way up (NOT the volume knob). Receiver's crossover to 80 Hz (that's not set in stone, but good starting point, mine is set to 80 and I like it). Set speakers to small in receiver's settings and LFE set to "SUB" only. Setting speakers to small will alleviate some stress on your AVR's amp. Different brand subs recommend setting the sub's volume knob to different positions (9 o'clock, 12 o'clock, etc.), so read the owner's manual for your sub before using your avr's set up program.
