    Which causes the reciever to work harder? I think 4 but can't remember.

    What would the difference be? I mean what do you mean "work harder"?

    An 8 ohm load is easier for an amp to drive than a 4 ohm load.

    Yes, a 4 Ohms driver will draw more current at the same output voltage from the amplifier than a 8 Ohms driver.

    But that's only part of the story. The amplifier is optimized for one of the two, although it will often allow both (preferably through a switch).

    If possible, choose the impedance given in the technical specs of your amplifier for optimal results.
