Correct a mundo!

And if you think about it the audio signal is an AC (alternating current) signal. The speaker moves in and out in reponse to polarity changes caused by that AC signal.

RMS would be a sort of average current, or a continuous current, both the positive and the negative and is an important measurement in AC. If you add up all the currents together, both positive and negative then you will get close to zero! We know that isn't the case because for a brief moment the current is positive, then goes back negative. Think of a sine wave where the negative peaks (on the bottom) are flipped up to the positive side, then an average line drawn across all the peaks. THAT is the RMS value.
