    Can someone tell me which speaker wire is positive on an AC15C1? There is a black wire and black/red wire and I can't remember which one is supposed to go on the + speaker terminal.

    Normally, the black wire is the negative

    There is a nice trick with a 9V battery. Connect the wires to speaker terminals. Take that battery and stick the tip of the speaker cable jack to battery's (+) pole, then stick the sleeve of the speaker cable jack to battery's (-) pole. It will move the cone of the speaker forward when it's wired "right". Switch the connectors on terminals if the cone moves backward.

    But it's up to you how you wire it, there is no "standard". Speakers can "live" in both settings. There can be a problem with a polarity when one plays with a band or uses two amps, but it's other story...
