Someone describe what they would consider the minimum electrical

system someone should use for this beautiful monster.

I wouldn't use ANY less than a 200-amp alternator, a primary battery, and a Powermaster D3100. I would suggest two D3100s.

I got a little testing done. These are "unofficial" results. Until I use Jacob's equipment I won't consider it official. I did not use peak hold on my meters (and yes they are true rms). Instead I recorded my 3 meters all in real time with my camera reading ac voltage output, ac amperage output, and dc voltage input at the amplifier. Then I slowly rolled into the volume to prevent spikes and held it for 5 seconds so the readings could level off.
Results:

2,318watts @ 2.9ohms after rise @ 13.7v after drop.

4,040watts right around 1ohm after rise dropping to 11.3 volts.

Again, these were not peak hold measurements and these are unofficial results. I'll get some official results from Jacob's equipment on Monday or Tuesday. That way all our testing will be uniform from the same meters.

sounds about right... getting a mean between the rest voltage and lowest voltage, i would say the amp will easly do rms spec very linear @12.5 volts... must sell my 1750 to get one of these.

In SPL Derrick was 1 dB up at 1 ohm vs. the 3000D!

We got similar numbers on my clamp at the shop:

3980 @ 0.25 rising to 0.65 @ 11.2v (engine on)

2050 @ 1 rising to 2.44 @ 12.2v (engine off)

These are measured ~6-10 seconds in as my meter takes some time to put up a reading - it does power all at once.

Raymond Farmer's 12v Testing:

"Okay, I have done my SAZ3000D 12volt power test. I would like to say, WOW!!

My nominal ohm load was 0.5 ohms. I did plenty of test but I got the amp to do its power at the proper settings and did 3 test and took the average.

I used 2 x NSB-g3100 to power the amp, Starting voltage 13.2

Test 1

75.1 volts

39.9 amps

2996.5

box rise 1.88

voltage drop 12.2

Test 2

75.1 volts

37.7 amps

2827.5 watts

box rise 1.99

voltage drop 12.1

Test 3

76.0 volts

39.5 amps

3002.0 watts

box rise 1.9

voltage drop 12.1

Average of 3 test

75.4 volts

39.03 amps

2942.86 watts

box rise 1.92 approximately 2 ohms

So 2942.86 watts @ 2ohms @ 12.1 volts

That is some power!!!"

Silly question here, has anyone done 4 ohm nominal testing?

 

[Papermaker85 5,000+ posts]

what meter you have J?? im thinking about getting the B&K clamp/power meter measures VA VAR HP etc.. thing that go me thinking is the 3% tolerance... when your tring to troubleshoot i rathere have fluke but there near 2Gs!!

feed back on the meter please.. i know the amp kicks ***,lol

I have an Extech unit - it will read VAR, VA, and HP as well //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I have had great luck with it.

Nope - but I'd say it wouldn't be very impressive with a typical rise to 6-8 ohms or so! I don't really recommend running these big high current Class-D amps at 4 ohms as they generally don't perform very well.

I did some more testing recently :

POWER : 3660 Watts

AMP VOLTAGE (measured) : 65.84 V

AMP CURRENT (calculated) : 55.58 A

ACTUAL IMPEDANCE (calculated) : 1.18 ohms

SUPPLY VOLTAGE : 11.9 V

On that note... these are about to be back in stock in a few weeks.
