BulletInjection Posted January 2, 2010 Report Share Posted January 2, 2010 efficiency goes down as ohm load does4ohms vs 1 ohm could be a 20% loss in efficiency with a great amp Well power efficiency anyway right? It will pull more current but if you have enough electrical power to back it up there is a large amount of power to be had... one could rule the world with enough power..... eh?

Boon Posted January 2, 2010 Report Share Posted January 2, 2010 To be honest, we don't even know if they used True RMS DMMs. So we could be looking at peak output voltage. The power output seems too high... let me crunch the numbers... 2526 @ 4.2 ohms = 1263 @ 2.1 ohms per amp. P=V^2/Z 2652 = V^2 V=51 51v @ output implies that with a true 2 ohm load the 2 amps would be doing around 5kw - and we all know those amps don't pull that kind of number... If you divide it by 1.414 (RMS to Peak conversion) you get 1839w/amp which is probably a bit closer to the truth... IN FACT if you divide by 1.414 again you get right around 1300w/amp (non True RMS clamp meter) which is bang on what the factory test results claim. So yeah. That's my input on that one. 10.x volts fo' life! Link to comment Share on other sites More sharing options...

MXmike800 Posted January 2, 2010 Report Share Posted January 2, 2010 wow nice, anyone looking to buy an ap3000d? i have one BNIB for sale PM ME Link to comment Share on other sites More sharing options...
EricR Posted January 2, 2010 Report Share Posted January 2, 2010 2,525 watts at 4 ohms? i don't believe that shit. did he also mention what the THD was? probably around 5% i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

clouduz Posted January 2, 2010 Report Share Posted January 2, 2010 yea seems numbers might be slightly inflated to me Link to comment Share on other sites More sharing options...
EricR Posted January 2, 2010 Report Share Posted January 2, 2010 buy my amp and try it out. 60$ shipped? i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?
