Actually that's not quite true. (sticks on pedantic hat) The Amplifier will use DC as the basis for a supply, but the actual signal going to the speaker will be AC, in the form of the frequencies it's meant to produce for sound and music. Applying a direct DC current to speakers can actually burn the coil, as they rely on the cone movement to cool the coil, and not overheat it. DC would have the coil sit stationary, and heat up till it burns, if the voltage/current is high enough. (/pedantic) biggrin.gif

As to the OP's question, how about this?

only the output voltage matters, I do not think the amperage would. However, if you go lower, your power source might not allow you to turn up your speakers as high. nothing really wrong with going higher, since you just wont ever use the maximum amount. I would actually go a little higher if it were me.

just make sure it is a 120v input, the same output voltage, and you will need to make sure the hardware is compatible. If it has one of those stupid round plugs, you need to make sure it is the same size, and that the positive and negative are connected the same as yours. If the plug is different, you could always cut the plug off of your current power supply and use that, but you will need to make sure that the leads are not switched.
