Actual power of 3000d

[Travo-18 1]

I'm very intrested in getting 2 3000ds and this would be my first time ever using Sundown and I will be only person within 150miles of me that will be running Sundown and from browsing the forums I see lots of reviews saying they are well under-rated and they put out 3000+true rms @ 1ohm and 14.4volts.

I have a damn good eletrical and I can keep my voltage at 14.36v to 14.48v at full tilt. So if anyone can tell me the actual power @ 1ohm and 14.4volts a 3000D can put out, I would really appreciate it.

Thanks

Thanks to Sean we did some power testing on the SAZ-3000D yesterday. Power testing was done on two RE MT 15" woofers, dual 1 ohm coils (0.7 ohm DCR) with a rise to around 0.87 ohms at our test frequency.

Power Output at Maximum Volume before Protection:

67.4 volts

77.1 amps

5196 watts

Power supply voltage was 16.5 volts at rest dropping to around 14.5 volts. So consider this a 14.5 volt output rating.

Our clamp meter ran out of steam at 400 amps so we measured efficiency at lower levels:

3294 watts @ 84% efficiency (252 amps draw)

3938 watts @ 81% efficiency (316 amps draw)

4424 watts @ 74% efficiency (392 amps draw)

We didn't have an electrical setup to run 12.8 volt testing available at this time.

That's from the sticky at the top of sundownz forum... if you're staying at 14.4 full tilt, i'm guessing this would fall in your category

If I remember correctly this amp does over 3000 watts rms @ 11 volts. Probably closer to 3400 watts rms at 14.4v. But you'd need an electrical that could handle ~400 amperes of current draw (per amp) to maintain that at full tilt.

Yeah i think in another sticky it was 3200 or so at 11 volts

Edit: found it.

65.8 volts

49.2 Amps

1.33 ohm calculated rise from 0.6 ohm DCR **

3237 Watts

14.4 volts rest dropping to 10.75 volts

beastly, if you ask me

So is it around 3400rms or 4000rms? The one tests says it was rated 3938 @ 85%effciency but that was with 16.5volts being ran to it but to consider it a 14.5v test, how in the hell is that a test for 14.5v when 16.5v was being powered to it. I know the voltage drop was probably to 14.4v but that still isn't considered a 14.4v test when it has 16.5v of current to back it up.......?? I'm confused.... And I do have the electrical to back it up and maintain a 14.4volts at full tilt when I had my 4 kicker ZX2500.1's which was in total about 10K rms I could stay at 14.3v at full tilt daily

you have any pics of that dual alt set up?

[Travo-18 1]

Sure do! They are 2 300amp alts from Motorcityreman.com
