    Just in case your search ended up at a site that sells overgauged /overpriced cables: assuming that your cord is less than 8 feet long to have less than a 1% insertion loss, (which is massive overkill as even 10% can't be heard) you need a 12 ga cable. OTOH 14 ga is quite sufficient from both insertion loss and current capability standpoints.

    and IMHO, for the typical 3' or so lengths used for head to cab connections, even 16 gauge is plenty for even twice that power. hell, ive got a 1600 watt heater beside me (turned off, lol) with zip cord for the mains. of course, the voltages are much lower in the case of speaker wire. at these lengths, the resistance of 16 gauge wire is inconsequential. a "280 watt" marshall cabinet has 18AWG hook-up wire throughout.
