    Hello Shawn McCarty,
    Thanks for writing in.
    We find out this item200150
    But we are not sure if it is the one you mean. If yes, please kindly notice the max input current is 15amp. It is easily to be damaged when input is over 15amp.
    If it is not the one you bought, please kindly send us the prodct link or ASIN number for confirmation.
    Best regards.

    HellO,
    For this item, we suggest power supply can be 12-24V. You need to think about if the power supply can offer enough power to your speaker. For some small speaker, 12V/5A power supply should be suitable.
    Best regards.

    Hello William Chance,
    Thanks for writing in.
    Would you please firstly help to confirm if it is this item?

    And do you mean your power has two hot wires? This meter can’t hold two hot wires, it may be damaged in that case.
