    Are these power ratings Strange?

    Hey everyone i was looking at the power ratings on the new Kenwood eXcelon X811D amp.

    I was reading on the forums and people were saying the dynaic power is just a fancy name for its Peak Power.. However the dynamic power this amp shows is alot less than its peak..

    POWER RATINGS (CEA-2006 STANDARD)
    - Dynamic Power: 566 Watts
    - Output Regulation: Under 0.2dB (4 ohms)
    - R.M.S. Power Output (1-Ohm/1-Channel): 1016 Watts (1.0% THD+N)
    - R.M.S. Power Output (2-Ohms/1-Channel): 919 Watts (1.0% THD+N)
    - R.M.S. Power Output (4-Ohms/1-Channel): 533 Watts (1.0% THD+N)
    - Signal-to-Noise Ratio: 74dB (4 ohms)
    - Signal-to-Noise Ratio (Bypass): 74dB (4 ohms)


    Does anyone know what the dynamic power really is? Also it says these ratings are cea-2006 standard.. what does that mean? Will the amp really do these ratings and its certified by someone?

    Thanks,

    i believe he is saying the load being your sub. or i suppose if you really wanted to just an inline resistor?

    dynamic power ratings on my old mtx were meant as when your car was running and it was getting ~14.4V. it was rated normally at 12.5 i believe.

    I'm still confused. If the dynamic power is listed as 566 watts, is the amp capable of delivering 1016 watts at 1 ohm? Thanks.

    From CEA-2006:
    http://www.customdistributing.com/Do...IA_CEA2006.pdf

    Dynamic Power: This spec used to
    be called “headroom”. Headroom was
    an indication of how much power an
    amplifier could make reproducing short
    bursts or musical transients. Amplifiers
    can make more power when reproducing
    transients than they can sustain for
    long periods of time. Headroom used
    to be stated in decibels, but dynamic
    power is expressed in watts. It’s easier
    to understand without breaking out
    your scientific calculator to convert dB
    to watts. You always carry a scientific
    calculator when you shop, right?

    Always trust an amp with the official CEA-2006 (or up in the future) badge on it
