BJD3 Posted April 4, 2009 Report Share Posted April 4, 2009 I don't know if I will be able to explain this properly but If I buy a mid-range powered amplifier, like 1500 RMS @ 1 ohm, but wire it to 4 ohms for 600 WRMS, would the demand on the electrical system be the same as if I ran an amplifier that was 600 WRMS at 1 ohm? Basically, which would be the "easiest" to power, a higher powered amp at a higher resistance, or a lower powered one at a lower one? Anti Peel and Seal...lol You may be offended by the above.

Guest KyleCannon Posted April 4, 2009 Report Share Posted April 4, 2009 If you ran a 1500RMS amp at 4 ohms instead of one it will be easier on your electrical..... this is because it is more efficient to run at that level. Someone correct me if i am wrong for example: P500-1bd @ 1 = 70% efficiency versus a T100-1bd at 4ohm = 87% efficient Link to comment Share on other sites More sharing options...

creyc Posted April 4, 2009 Report Share Posted April 4, 2009 The power supply might have more storage capacitance in the larger amp but these don't consume large quantities of energy by themselves, they merely store it until it's needed by the speakers. Using a larger amp at a higher ohm load will almost always be easier to run due to increased efficiency. I've noticed this in person switching from my old amps to a SAZ-3000D @ 2 ohms. 2001 Chevy Blazer (2) SAZ-3000Ds (2) custom 18" Madmax subs in a second row wall Rockford 600-4 Pioneer PRS components Pioneer P800PRS deck Link to comment Share on other sites More sharing options...
Dale Posted April 4, 2009 Report Share Posted April 4, 2009 It depends on the voltage. Power is voltage X Current, so if the circuitry operates at a higher voltage, less current is drawn Furthermore, 600W is 600W, whether it be at 1 ohm or a million ohms.
