Impedance matching car audio

That speaker impedance rating on your towers and bookshelf speakers is held up as a mystery—something strange and mystic, yet dangerous. The bottom line is that people are confused about speaker impedance. I think the easiest way to define speaker impedance is to say that it is the resistance any speaker gives to the current and voltage being applied to it. In a nutshell, a loudspeaker is a big resister—a really cool one. Speaker impedance changes based on the frequency of the signal fed into it.

What Speaker Impedance Means and Why It Matters

The reason for using a sound level meter is because once you have your system complete, it may take a big increase in amplifier power to see a slight 1 to 3 dB increase in sound pressure levels, just think of how much money it would take to double the number of amplifiers you have! It would be much cheaper to buy sound level meter, re-tune and design your system better. Noticing what changes in design makes your dB level go higher with a use of a sound level meter. Unless you have had a lot of experience you may not perceive this correctly. Furthermore, system changes can cause resonant frequency changes. This is important because the human body does not accurately rate sound pressure levels, Especially at different frequencies. I have seen many people incorrectly guess the sound pressure level of a relatively low dB into thinking it was dB, because it was at a very low 24hz instead of the usual 45 to 65hz. If your system is using a ported box, a sound level meter will let you see how much slight changes in the length or size of the ports can make a big difference in your sound pressure levels. Junk brands means you or your local Car Audio shop have never heard of it, or never heard it with their own ears. Also just because something is low price does not mean it is junk.

In an earlier article we looked at the issues involved in connecting multiple speakers to one amplifier. In this article we look at some of the practical ways of wiring four speakers to each amplifier left and right. For example, it is normal to have your main HiFi amplifier in the lounge room. It is also common to want to have some speakers in the family room, outside patio or pool area and in the workshop or garage. If you need to connect just 2 pair of speakers to a HiFi stereo amplifier that is, 2 speakers to 1 amp , see my article on How to connect 2 speakers to 1 amplifier.

Seldom do the packaging and included product manuals explain what impedance means or why it matters to you. Impedance is like great rock 'n' roll. Understanding everything about it is complicated, but you don't need to understand everything to "get" it. When talking about things like watts , voltage, and power, many audio writers use the analogy of water flowing through a pipe because it's an analogy that people can visualize and relate to. Think of the speaker as a pipe.

But what is car speaker impedance? Speaker impedance, measured in Ohms, is the voice coil total resistance to the flow of electric current as it operates with a musical signal. Inductance is a bit different from resistance as it changes as the frequency changes. This is called inductive reactance. For car speakers, this means that the real impedance the total resistance actually changes a little bit as music plays! When we talk about the impedance of a speaker, most of the time people are referring to the category general range of the speaker as used to match home or car stereo amplifiers. When a musical signal made up of alternating current is applied to a speaker it generates magnetic fields as current flows through the tightly wound wire coil.

With more information to play with, high-resolution audio tends to boast greater detail and texture, you'll hear every song in all its detailed glory — just as the artist intended — for sound that's more engaging, dynamic and lifelike.
