These are from Derrick's Explorer :

Starting battery + 2x Powermaster D3100s used for testing

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

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

These are from Ray Farmer:

Okay, I have done my SAZ3500D 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!!!

These are from my Jeep on 16v:

6x Powermaster D1000s used for testing

17.9 volts rest - did not measure voltage drop.

10,320 watts from the pair @ 1.5 ohms each after rise starting at 0.5 DCR

5160 each

11,470 watts from the pair @ 1.3 ohms each after rise starting at 0.5 DCR

5735 per amp

Anyone else please share your results.

This is not exactly a power test but here is a swap :

CIMG2466.JPG

* American Bass 1000.1 (Two 500.1 in one case) -- Equal to TWO SPL Dynamics D5

CIMG2465.JPG

* Two SAZ-3500Ds

VIDEO WITH 1000.1 @ 1.33 ohms per side:

* 153.1 dB

VIDEO WITH 3500Ds @ 0.33 ohms each:

* 155.1 dB

The 1000.1 would NOT RUN at the 0.33 load at all. Protection at 125 dB output.

Also... another swap that was done... SAZ-3500D vs. American Bass VFL-400.1 (equal to Celestra DA6K) running at 1/2 ohm each.

The SAZ-3500D gained 0.5 dB SPL.

Electrical supply consists of vehicle running with stock alternator + two Stinger SPV-1700 batteries. Sub-woofers were two American Bass HD 15s.

Bench power testing with ONE Stinger SPV-70 and ONE Pyramid 52-Amp Peak power supply.

Two videos. One of power test one of voltage test used to calculate the 1.89 ohm actual impedance.

2340 watts with a voltage drop to around 11.4v by the time the Power meter kicks in. Voltage drop measured at battery as well - could be lower at the amp by a tenth or two.

* Power Test -- Put it in HQ to see the Power Meter better

http://www.youtube.com/watch?v=WvA7DomXrZg

* Voltage Test - 66.5v so calculated impedance is 1.89 ohms

Test with power supply at 2340 watts was 66.5 V / 35.18 A (you can see test video for 66.5V).

So you an assume for 2240 watts it was very close to that as well.

theoretical impedance?

impedance real?

you can measure each of the A, and V?

and not directly using the result of the pliers?

My load is 1 ohm nominal / 0.7 DCR and actual is 1.89 ohms calculated from power and voltage.

Another test...

One SPV-70 Battery + 52-Amp Power Supply

0.5 DCR (One Nightshade 15) rise to 1.42 ohms -- 2660 Watts with voltage drop to 11.2v

http://www.youtube.com/watch?v=DDaFy5OvGdc

Measured Voltage = 61.5 V

Measured Current = 43.9 A

Calculated Current = 43.25 A (so this is just as accurate as measuring for all intents and purposes)

Measured Voltage = 61.5 V

Measured Current = 43.9 A

Calculated Current = 43.25 A (so this is just as accurate as measuring for all intents and purposes)

but these are the calculations you? or measured separately?

from video, you see only the final result, which indicates the strument

If you have one sitting at the shop you can swap out my 3000d for a test if you want. Just to get numbers cant afford to upgrade any further haha.

I measured them after taking the video. It is difficult to hold the camera and adjust all the instruments at the same time.

ok, maybe this evening post our new results
