gonna try again since i couldnt watch my own thread.
im not good at voltage and watts and so on.
i have the subwoofer in the pic related and i need a 15v AC adapter to power it, i wonder if i can use a 12v AC adapter to power it or maybe a 15v that is supposed to power something else?
in case you dont know what subwoofer im talking about, its the csw250
Most likely a 12 volt won't work. You could try. I doubt it would hurt anything. But it either won't power up. Or it will and just won't sound very good or go very loud. I'd stick with the 15 volt
