i have a jl 300/4, which is 75 watts rms. does it always put out 75 watts rms even at low levels, or does it reach that rms the louder i turn up the volume?

A power amplifier's output power in watts depends on it's input power that's "driving" it. So if you turn the input driving power down very low, the power amplifier's output will go lower in direct proportion to the amount of input power. "75 watts rms" is the rated maximum rms power output for your power amplifier at it's full rated output. Most of the time at normal listening levels, the output power will be much less, typically a few watts at most. The reason you want a very powerful amplifier is not because you normally need to listen to it at the maximum power level. Instead, it's because the sound quality will be less distorted at normal listening levels compared to low power amplifiers (like a 2 watt amplifier)

I hope not!!! You'd be very deaf!!!
That is the maximum output the amp can give. Audio signals swing from positive to negative rapidly, drawing the most power at either positive or negative peak, but then immediately swing back past 0.
An AVERAGE output of 10 watts would be VERY loud. You need the higher wattages to pass the high and low points of the wave.
You probably start to hear audio at about 1/2 watt or less.... comfortable at 5 watts etc.
Bass signals, because they are slow (low frequency) draw a lot more 'juice' than high frequencies.
Why the high power need? To simply double the volume level without distortion requires TEN TIMES the power!!!!

no it does not always put out 75 watts. This is the most it is rated to put out safely and with good performance. You would need to turn the volume all the way up on a loud part of a song to get to the max level.

I am not entirely sure...but I think that is the maximum RMS that it will put out. Therefore, it will put out lower RMS at lower volumes and will go up until it gets to 75W.

Take into consideration that the power written on the amp is at 14.4V and u can get maximum 13.8V in ideal conditions and in reality u get like 12-12.5. So the power is lower than 75W anyways

Simple answer, no, it will fluctuate with either the signal or the volume.
