I would like to see this aswell.

 

I think your math is off a bit. Might want to re-check that. And look at the other test results I sent you.

They were hitting 5655wrms on a strapped pair @ 84% efficency drawing 180Amps from EACH amp not one. Maybe that is what you over looked. Not sure though. All im saying is this is suppose to be a 3000Wrms setup and to almost be doubling the output is impressive and depending on your class they very well could be a great competition amp and then with the 3000D's coming should be close to 10K strappped if not over. The Sundown's also handle upto a 18V input so could sqeeze a bit more maybe. And if the Crossfire does that, thats great. I have no problem with crossfire they make awsome equipment. But for a Canadian retail price of $1500 to get over 3000Wrms rated and over 4000Wrms in real use is outstanding. And right now with the sale going on its $1100 Cdn.

 

Here you go normal 14V system tests.

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

AND UPGRADED ELECTRICAL SYSTEMS (and this is at 1ohm!)

Here's the setup, a pair of Sundown Audio SAZ-1500d's strapped at 1 ohm.

In the box used in the test (a single Funkin Audio MF12, dual 2), rise went from 1 ohm to 2 ohms during play. Here are the results:

Notes:

* Highest power on 16.0v rest was 4663 watts on 14.3v
* Highest power on 16.5v rest was 5136 watts on 14.3v
* Highest power on 17.9v rest was 5677 watts on 15.5v
* 84% efficient on 15.0v and 180 amps of draw each amp

There was a 10% increase in power starting 0.5v higher with an ending voltage being the same. There was another 10% increase when starting at 1.4v higher and ending 1.2v higher. This would tell me that a lowest voltage over 16.5v likely wouldn't be much of a gain from below that.

No matter how ya look at it, tapping the 5700 mark on 15v isn't too shabby from a pair of 1500 watt amps.

 

To be perfectly honest I believe it might. Not sure though don't mark my words but it I have not seen any real world tests on the z1. Not overly familiar with the amp. The 3000D will be build the same way as the 1500D and capable to dip into the lower impedence area allowing for increased output. From the sounds of it the amp will do about what a pair of the 1500D are doing now and then will also be strappable. So around 4500-5700wrms depending on electrical system each amp.

 

how much is a z1?

 

Around here they go for a good two thousand bucks or so

 

Hey how are your Sundowns working out??

 

So far I'm pretty impressed. I have only been able to strap them at 4 ohms so far since I only had access to an SVC 15" (which is no longer with us after the testing) this Christmas, but I put a true rms multimeter and clamp on the pair for a few burps and was getting just over 1800 watts, car on with a stock alternator and a crappy little 600CCA battery - I intend to swap it out for a kinetik or whatever is most powerful and will fit under the hood by summer.

Getting a couple hundred watts over the rated power (800W at 2 ohms x 2) with such a poor electrical system was pretty cool. I look forward to testing at a lower load with the SX's.

 

wow... you car has the same shitty electrical system as myne lol. and being junk is what they have in common lol
