    Sundown Audio test Results

    Ok.. I've been an arseho long enough... results from teh sundowns...

    Test Vehicle.. mine.. 05 aveo..

    RMS clamp and dmm, as seen in the 12" test session..

    This testing includes recent results, and not so recent..

    woofers used.. 2 Mags (1.9 dcr per coil), 2 FI Q 12's (1.4 dcr per coil)

    either used 1 sub or both of the pair for loads..

    pure 60hz sine was used to tested.. just under audible clipping

    1 amp, single 1000ca everstart maxx, factory alt

    4 ohm nominal = 518 watts @ 88% efficiency (voltage fell from 14.3v, to 14.0v)
    2 ohm nominal = 948 watts @ 85% efficiency (voltage fell from 14.3v, to 13.6v)
    1 ohm nominal = 1510 watts @ 78% efficiency (voltage fell from 14.3v, to 12.4 volts
    .5 ohm nominal = 1615 watts @ 72% efficiency (voltage fell from 14.3v, to 11.8v)
    .35 ohm nominal = 1748 watts @ 67% efficiency (voltage fell from 14.3v, to 11.4v)

    amplifier was protection happy @ .35 with tones, and some music.

    IMO.. one 1500d should be limited to 1 ohm nominal use in factory electrical systems.. for the sake of the car.. not the amp

    now... to have fun with some juice..

    1 amp, single 1000ca everstart maxx, 1 Eagle Picher 12a5000, factory alt

    4 ohm nominal = 520 watts @ 88% efficiency (voltage fell from 14.3v, to 14.1v)
    2 ohm nominal = 960 watts @ 84% efficiency (voltage fell from 14.3v, to 13.7v)
    1 ohm nominal = 1635 watts @ 75% efficiency (voltage fell from 14.3v, to 12.8 volts
    .5 ohm nominal = 1890 watts @ 71% efficiency (voltage fell from 14.3v, to 12.8v)
    .35 ohm nominal = 2245 watts @ 65% efficiency (voltage fell from 14.3v, to 12.8v)

    amplifier did fine @ .35 with tones and music with the added battery

    2 amps strapped, with both batteries (for the sake of not typing it over and over... voltage drops from 14.3v, to 12.8 the entire test... lol

    4 ohm strapped = 1900 watts @ 82% efficiency
    2 ohm strapped = 3150 watts @ 72% efficiency
    1 ohm strapped = 3740 watts @ 68% efficiency
    .5 ohm strapped = 4425 watts @ 65% efficiency
    .35 ohm strapped = 5415 watts @ 62% efficiency

    amps would only tolerate a VERY short burp @ .35..

    So there.. merry xmas

    yeah for efficient 4+kw at ~$1200

    Strapped is nuts. Can these go on 16 volt setups?

    Re: Sundown Audio test Results

    just wondering, is this how the power was calculated:

    V_rms * I_rms = RMS watts ?

    and

    when you write the nominal load; is that based on both drivers having dual 2 ohm coils or is that the DCR?

    Re: Sundown Audio test Results

    well...This is about where I thought they would falll. I knew there was no way that a strapped pair could do 5kw daily....but they did do well. What would loyd suggest the lowest you take a strapped pair daily 1 ohm (showing each amp .5)?


    any who...Strong amps.

    they arent rated for .35 ohm on the website im sure. RATED at 1 ohm + i believe....and that being said (even at .5 ohm) they are rated dead on.

    Great amps, not trying to take away anything from that... but that's @.175ohms EACH... and a BURP.

    Still solid.
