Yup, they all mention 2-2.2ohm, but cant see any mention of wattage.
Cool. I assume by using a higher wattage resistor, its not going to do any harm? Just it can handle more should it need it? Not knowing much about electronics I dont know what damage I would do using the "wrong" wattage resistor. From a quick bit of googling, if it was too low it would burn out, if it was too high, well there doesnt seem to be a too high
