amp question? how is this possible


ALPINE408

Recommended Posts

I have an amp and a pair of 15's brands do not matter

I burb at .5 ohms and I hit a 151.9 I then wire to 2 ohms and I hit a 153.1

How is this possible......

Waits for the but but you have more rise at 2 ohms comments....

Have you ever had your woofers blown?

Dampening factor?

How was the voltage drop?

I know Ive seen people calling amps inefficient due to their tests at 1ohm and that it was no where near what the manufacture published.

I know amps efficiency rating is at 4ohms (even on mono blocks), so maybe something with the amp being more efficient and since the drop was not as bad it was actually able to make more power.

But then again those same people think that cea ratings are at the amps lowest stable impedance as well, when its actually at 4ohms with 14.4 volts, so it is very possible for an amplifier to make its cea rated power at 4ohms, but fail miserably at 1ohm.

It could be also possible that the amp couldn't handle that .5ohm and it was stressing very hard and all the power it made was clipped to hell causing the woofer to have a messed up stroke and not having as much xmax as it should.

Dunno but that is strange, and thats about all I can think of.

Are you reaching protect?

Voltage at your amp? (both input and output)?

What about peaking at a different frequency, have you checked for that?

Less losses in a higher nominal impedance.

Krakin, are you some sort of mad scientist?

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . .

What you hear is not the air pressure variation in itself

but what has drawn your attention

in the two streams of superimposed air pressure variations at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space

Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears,

thus no formula can achieve a definite effect for every listener.

yeah i think to answer properly we need to know the electrical components at play here as well.

Voltage drop is not a factor

But as I see stated over and over and over again you have less impedance rise at .5 ohms vs 2 ohms

And the amp is proven to do more power at .5 ohms so according to many many members here you have to wire to .5 ohms or lower to compensate for impedance rise and thus all ways giving more spl
