I would think that most usb speakers are pretty inefficient (meaning a 9v won't last very long). You would use an voltage regulator such as an LM317 to convert voltage. How about a bigger 6 volt battery and skip the regulator, the speakers probably wont care......especially if they are cheap.
yes p.s. = wall wart or ac to dc adapter , the boos ones , like i mentioned have the noise filtering built in . it very well could be that having it on breadboard is the issue . have you tried moving it ? also the input cable , is that a shielded wire ? i have done some breadboarding and they always are a bit noisy until they get boxed up . if it was me , i wouldnt spend TOO much time debugging it , rather get it boxed up , then hopefully it would be quiet , but you wont know until you try i spose .
