    The maximum allowed current for each speaker is 3.73 A

    Explanation:

    Given;

    resistance of each speaker = 4.9Ω

    power through each system channel = 68 W

    the current through the fuse of the speaker circuit = 4 A

    From ohms law, the maximum allowed current for each speaker is calculated as; '

    P = I²R

    Where;

    p is power

    I is current

    R is resistance

    I = √ (P/R)

    = √ (68/4.9)

    = 3.73 A

    Therefore, the maximum allowed current for each speaker is 3.73 A
