    PMPO (peak music power output)
    RMS (Root mean square)
    Power

    There are two very different expressions of power; the first is known as PMPO (peak music power output) or "commercial watts." This is a misleading measurement and is often used to make audio components sound better than they actually are. PMPO is the peak amount of power that can be derived from an amplifier given perfect conditions and can only be sustained over a very short time (a few milliseconds). PMPO is also used to measure speaker output. Once again this is merely the peak amount of power that can be run through a speaker without blowing it. Should this amount of power be applied for more than a few milliseconds the speaker will blow. The next measurement for power is RMS (Root mean square) and is the maximum continuous power that can be derived from an amplifier or run through a speaker. This is a true measurement of what you can expect from any specific component of an audio system.

    Since there are many ways for a company to measure the power output of their product, CEA(The organisation Consumer Electronics Association) created the CEA-2006 standard[1]. The standard provides a guideline for car audio manufacturers to follow. Although this is a voluntary standard, all major manufacturers have agreed to use it to measure their head unit and amplifier power output. The rating is also clearly stated on the product with the CEA2006 logo on the packaging box, which makes comparing two competing products easier.

    [edit] RMS vs PMPO

    There is no relation between RMS and PMPO as they will differ greatly from component to component; however it is agreed that on average if one wishes to derive RMS from PMPO the ratio is one into four, (or 4 watts PMPO = 1 watt RMS) this is however only an average and should not be deemed accurate.
