Thanks. Thinking might be the same because they will have the same peak voltage.
That might be the case if you were playing white noise. However, pink noise has higher energy in the lower frequencies which is why subwoofers need gobs of power and tweeters do not.
edit: I misread the frequencies in the original post, whoops. The power consumed will be just about the same between the two examples given, or at least so similar that it wouldn't matter enough to warrant a change in equipment or wiring or fusing etc.

Regardless current consumed will be comparable.

It seems like most people don't care to actually understand reality.
The OP didn't give any specifics such as output power or impedance the amps are driving so it's impossible to make an educated guess.
However, if we assume that both amps have similar power and efficiency ratings and are driving the same impedance, then the max current draw would be the same.
Both amps would draw the most current, for argument let's say 40 amps, at the same frequency, say 100 Hz. Although amp B goes past 500 Hz (where amp A stops) it would have drawn it's peak current at the lower frequencies. As it continues past 500 Hz the current draw (all things being equal) wouldn't exceed 40 amps so both amps will draw the same maximum current.

Don`t you hate when people asked half cooked questions?
Half cooked question deserved half cooked answer....

Thanks. Both amp and speaker are identical in the example above. My PA woofer and midrange can play fullrange. I level match my amplifier to the limit since my speakers can take more wattage. I'm wondering if it is easier for the amp when I'm using crossover than playing fullrange.. And oh! sometimes i want it to play it as loud as possible playing all at fullrange where I don't care about the tuning.
And btw I burnt my amplifer last new year when my friend played bass boosted music from youtube. Thats the reason why i'm asking for this question.
