Right speaker (the one which does not have the amplifier) does not work at all - not connected to the left speaker, not connected to another amplifier. Nada. Crap. Wonder how much return shipping to M-audio is going to set me back 
I was in the same boat... Unboxed, plugged them in, and halfway into my the first song, one of the speakers died. Tried power-cycling, tried swapping around the RCA plugs, could not get it to run right for more than 5 minutes at a time. Then I tried ditching the included connectors and used a 5-year old set that I got for $5 from Radio Shack. That was 3 hours ago, and it's so far so good. Suffice it to say that I'm not throwing away the packaging yet, but you might want to try this before sending yours back.
BTW, the back panel does get REALLY hot, and I'm only at about 25% volume. Based on the link below, I might try the TRS connection...
