    10%thd????

    Zapco amps giving out 10%THD????

    Zapco AG1000 1000w 2ch amp

    Specifications:
    10% THD Power (at 14.4 V, 1kHz, 10% THD): 900
    Crossover Frequency: 18 dB / oct
    Dimensions: 32.5 inches
    Dimensions: 7.5 inches
    Dimensions: 1.95 inches
    Frequency Response: 20 - 20000Hz
    Output Transistors: Bipolar
    Power Supply Transistors: MOSFET
    RMS Continuous Power (at 12.0 V, 20-20kHz): 250W x 2
    RMS Continuous Power (at 12.0 V, 20-20kHz): 450W x 2
    RMS Continuous Power (at 12.0 V, 20-20kHz): 900W x 1
    S/N Ratio (IHF A Weighted): 90 dBA


    900w at 12v... wonder what it'll give at 14.4...wow

    but thena gain, I don't understand this THD thing...

    your info is wrong...
    correct ratings are - <0.03% THD into 4 ohm

    EDIT - that spec of yours is if the amp is driven into clipping..
    check out the Zapco site under reference amps... then look at hte PDF manual... there is ag raph on page 10 showing power vs distorion... it shows that if the amp is driven up to about 255 watts, the THD will remain under .015
    but if forced past that the THD shoots straight up to .1
    basically, dont force more out of it, and its all good...
