    SOrry to sound ignorant but I can't remember.

    When dealing with ratings for speaker power input:

    Say we had 150w at 8ohm

    AND

    150w at 4ohm

    Is there a difference, in other words is one more powerful than the other.

    Nope - 150W is 150W.

    What IS different is the voltage and current.
    For an 8ohm load the voltage would be 34.67V and the current would be 4.33A.

    For a 4ohm load, the voltage would be 24.5V and the current would be 6.12A.
