    Question about amplifier power?

    Technical specifications HXA 1000 QX
    Cont. power rating RMS/max. power
    at 4 Ohm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 x 350/700 Watt
    at 2 Ohm . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 x 600/1200 Watt


    Does this mean that if im running a single sub i can still turn up the gain to reach up to 700 watts at 4 ohms?

    or does it mean that at 14.8 vdc thats what the power would be?

    4 ohms the most you can get is 350rms and 700 max. Period.

    Re: Question about amplifier power?

    it means you will see
    350 watts at 4 ohm
    600 watts at 2 ohm

    if the amp does rated

    Re: Question about amplifier power?

    so even if i was to turn the gain 3/4 of the way it will only see 350 or does that number increase to 700 as i turn the gain up.

    if you clip the amp, you should see more power

    your helix amp should do rated power, how did you get such an amp and know nothing about car audio?

    I dont think you are understanding my concern or my question for that matter...

    I know that its running 350 at 4ohms, but in the manual it states 350/ 700 @ 4ohms.

    What im trying to determine is when does the amp reach 700 watts. In reality, any speaker resistance fluctuates as its functioning, it can go from 4 ohms- 20 ohms for that matter. In any case im assuming that during small periods of bass it can get up to 700 watts as a max for that impedance.

    That was all i was asking?

    Re: Question about amplifier power?

    a common test is "maximum sine wave output into a resistive load".

    this provides an easier way to sort out what is distortion, and where it probably came from.

    but this requires the power to change as the sine wave changes.

    so on average you get 350W to the speaker, with the peak output being 700W. attempting to increase output may be possible, but would more significantly increase distortion.

    That peak power is the crest of the sine wave and has no real applicability.

    buy a DMM and print the gain seting tutorial and follow it step by step.
