In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.

Impedance of Car Speakers . In car audio, 4-ohm speakers are the norm. That's because car audio systems run on 12 volts DC instead of a 120 volts AC. A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers. So crank it up and enjoy.

In audio input and output circuits the impedances are principally resistive to make interconnection easier — the impedance won't change too much over the range of audio frequencies. However, the impedance to radio frequency (RF) signals will often be very different to that at audio frequencies in order to keep RF interference out.

Above all, remember that impedance is the resistance of an electric circuit to the alternating current that passes through it. This resistance is expressed in Ohms. The electrical circuit of a speaker and its speaker thus has impedance to the audio signal from the amplifier.
What Is Speaker Impedance and How Does It Work? - Audiosolace

In technical terms, speaker impedance (and to some degree, headphones impedance) refers to the load an audio peripheral sends to a connected amplifier when in use. Note that when we are using any audio peripherals, the audio signals being sent from the audio source to the peripheral are electrical currents themselves (see “audio signal”).

It will be simplified and broken down into a pair of headphones delivering high audio and low audio. Essentially, headphone impedance is how well your headphones can resist an electrical current. Most headphones with low impedance (impedance less than 25 ohms) can produce high audio with little power.
