Do lower frequencies draw more amps?

[GassenD]

What I'm wondering is, does it take more power to hit lower frequencies 30ish and below? I can go full tilt while driving to some dubstep (40hz and up usually) and never see below high 13s, throw on something that gets lower and I'm looking at low 12s..

It varies from build to build. I draw the most around 60hz

Oh wow!Do you know what causes that? Does box tuning factor into it?

Yea i was gonna say my voltage suffers on high notes. ..

I think it has something to do with the caps in the amp or something. ..

Capacitive reactance = 1/ 2pi * freq * capacitance

So as frequency climbs the reactive gets smaller, as it approaches zero it acts like a short drawing the most power..

But then again idk lol.

It high notes for me tho. In every build.

Yeah I can handle higher notes with really no drop at all while driving but the second I start in on something low I'm down into battery voltage..

it varies quite a bit due to fluctuation in your impedance curve

in a given install your impedance will not stay constant on different frequency

and this is why wiring low on music is a bad idea

My voltage suffers most on high notes and I notice that if I play a song that goes lower//higher than the audible range of the subs then it does almost nothing to my voltage even if the subs are still moving. Like if I play a 24Hz note with the subsonic filter off it does not effect my voltage because my subs are audible only from 28Hz to 72Hz; but it still is flapping away at almost full excursion.

So if I was wired higher, let's just say I only had one of my 15s and wired it to 2 ohm theoretically I would have less impedance rise and a more "constant level of power"?

no your impedance rise would be close (different amounts of power can cause different impedance fluctuation) to the same

think of it this way... at 32 hz you're rising from .5 to 2ohm and at 45hz you could be rising from .5 to 1.3

make sense?

Mmm I must be doing something wrong then, I have voltage drop like no other in the 20s.. No point in me even trying anything under 28hz because of the drop..
