If you have a high-end system, only a high-end cable will suffice in making the absolute most out of it — and that goes from everything from the mains cable, through to the audio interconnects and everything in between — including speaker cables! But those days are long gone! Starting from the top…. Speaker wire is used to create a connection between the loudspeakers and the amplification.

The most common — and the most effective — core material is copper: inexpensive and conducts beautifully. Most speaker cables feature two or more electrical conductors, and some form of insulating casing, often made of some sort of plastic. The world of speaker wire is very varied, and there are dozens upon dozens of options to consider — none of which we will be going into here we like to keep it simple, where we can!

But the the three most important things to consider when it comes to selecting your wire are these basic principles:.

The best thing to aim for his a high conductivity and a high thickness, with a lower length. Practicality will often dictate otherwise length-wise, but by keeping the length low, you keep the resistance low. This means less power is required.

Which gauge to chose is very dependent on a number of factors, other than length, and will involve some calculations involving the impedance. The lower the gauge, the thicker the cable. The impedance of a unit is fixed, which means it is a reliable unit of measurement for loudspeakers. It is pretty imperative to understand the output of ohms from the amplifier and the impedance of the speaker, as not doing so can result in a blown power amplifier.

Or worse: poor sound quality from the speakers! Mathematically, this becomes: Current in amperes or I equals voltage in volts divided by impedance in ohms. To quote from the above linked article:. So increasing the voltage increased the current.Click on the image to enlarge it or click here for the Adobe.

The resistance value comes from a long coil of wire inside each speaker called a voice coil. A voice coil is a coil of wire that, when placed inside a magnetic field, makes the speaker move and produce sound when driven by an amplifier. Speakers contain a long wound loop of wire called a voice coil. This increases the amount of stress and heat it has to handle. For example, connecting a 4 ohm speaker to an amplifier that is labeled as working with 8 ohm speakers would mean it would have to produce double the electrical current to the speaker!

The recommended speaker impedance ratings are usually listed above the speaker wire posts. A home stereo, for example, may often list ohms as being ok for use.

Also, attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see. They ended up with a burned-out amplifier. An amplifier can only handle so much heat and stress before it fails, so be sure to observe these rules. Be sure you wire speakers to meet the minimum Ohm rating you need. Speakers are different than other devices in that they work using alternating current AC instead of direct current DC.

This is good news! As I mentioned, speakers work by moving a cone back and forth in order to produce sound. The result is a strange and poor sounding stereo. When speakers are wired the opposite of each other sound waves cancel out. When wired the same, sound waves add together for more sound. Speakers that are wired differently sound poor because much of the sound is canceled out. So the most important thing here to remember is to wire speakers consistently the same way as each other.

The job of a crossover also called a passive crossoverbecause it use basic capacitors and inductors rather than electronics is to restrict the music production each speaker tries to produce.

Unlike standard separate speakers, 2-way and 3-way speakers that have a crossover can only be used in parallel and not in series. This is because unlike separate speakers with no crossovers, in this case, many sounds will be filtered out.


What this means is that little to no sound would be produced if another 2-way speaker is connected in series. In some cases, more speakers can be added to increase the amount of volume you can get or to place speakers in more rooms, more locations in your vehicle, and so on.

You also may have wondered what would happen if you bought an amplifier with twice the power of your present one. It increases a few decibels dB for each speaker added. This is because of how the human ear works and the physics of sound, along with how speakers work and how much volume they can produce for a given amount of power. Generally speaking, the human ear will hear a very small amount of volume increase for each doubling of acoustic power: about 3 decibels dB.

For most people, the small amount of volume increase you notice when turning up a volume knob 1 notch is somewhere around 3dB. It increases it a very small amount as far as your ears are concerned.

Most people need an amplifier that can produce enough volume to fill a room or vehicle and turn up the volume from time to time. I like to use 50W or higher per channel as a good rule of thumb when buying an amplifier. Have questions, comments, or suggestions? Be sure to leave a comment below or send me a message. Confused about tweeters? Thanks very much Marty you as an expert explained yourself clearly so as even a 73 year old I could replace the wiring correctly on my home stereo system. I have 2 Rockford Punch subs in a band pass box.

There is a wire connecting the two, then another wire leads from each subwoofer speaker and connects to only one positive and negative square on the side of the box.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 ampsee my article on How to connect 2 speakers to 1 amplifier. I have had many people over the years tell me it is easy to connect multiple speakers — all you have to do is wire the speakers in series.

In reality this wiring needs to be duplicated for the right side speakers too. It is the same as wiring each speaker directly from the amplifier, like this:. Wiring speakers in parallel is not a good way of connecting three, four or more HiFi speakers as it puts too much load on the amplifier as explained in earlier article.

Again this is not a recommended way of wiring four speakers although it will worknor is it very practical. Apart from the hassle of having to wire from one speaker to the next, if one wire is disconnected, then all speakers will stop working. Also each speaker affects the total load seen by the amplifier which will only allow it to work up to one eighth of its potential. This is closer to a daisy chain as each speaker and corresponding single wire forms part of a daisy chain loop.

This is a safe way of wiring four speakers without a switch box or separate volume controls. It is a combination of series and parallel. Providing all the speakers are 8 ohms, this will work as the total impedance is also 8 ohms.

While this will technically work, it is often not practical as you need lots of wires interconnecting all the speakers and there is no control over any one speaker — they all are controlled by the amplifier volume control at the same time. The easiest and a safe way to connect 4 pairs of HiFi speakers is to use a 4 zone speaker selector switch.

This is relatively simple to wire, just run a wire from the central location lounge room to each speaker. The box should also look after any impedance matching to prevent amplifier overload. It is normal to locate the selector switch adjacent to the amplifier. Remember to connect the lounge room speakers to one switch so they can be turned off when you only want music outside.

Please note, speaker selector switches are designed for multi-room installs in a home. They are generally suited for low power under watts amplifiers. They should be not be considered in a commercial install or for use with high output power amplifiers. Speaker selector switches can use various techniques to allow multiple speakers to be connected to the one amplifier, namely:. All these methods allow multiple speakers, but at a lower volume than using just one speaker.

This is logical as the signal is being shared by more than just the one speaker.Speaker Crossover Wiring Diagram — 3 way speaker crossover wiring diagram, car speaker crossover wiring diagram, component speaker crossover wiring diagram, Every electrical arrangement is composed of various unique pieces.

Each part ought to be placed and linked to different parts in specific manner. So as to make sure the electrical circuit is built properly, Speaker Crossover Wiring Diagram is demanded. How does this diagram aid with circuit construction? The diagram offers visual representation of a electric arrangement. However, the diagram is a simplified variant of the structure. It makes the procedure for assembling circuit easier.

There are two things which are going to be found in almost any Speaker Crossover Wiring Diagram. The first element is symbol that indicate electrical element from the circuit. A circuit is usually composed by many components. The other thing that you will get a circuit diagram would be lines. Lines in the diagram show exactly how each component connects to one another. The positions of circuit elements are comparative, not exact. The order is also not plausible, unlike wiring schematics.

Diagram only shows where to put component at a spot relative to other elements within the circuit. Though it is exemplary, diagram is a fantastic basis for anyone to construct their own circuit.

One thing that you must learn before studying a circuit diagram would be your symbols. The most common elements are capacitor, resistorbattery. Additionally, there are other elements such as floor, switch, motor, and inductor.

All of it depends on circuit that is being constructed. As stated previous, the traces in a Speaker Crossover Wiring Diagram represents wires. At times, the cables will cross. Injunction of two wires is generally indicated by black dot on the intersection of 2 lines. Colours can also be utilised to differentiate wires. Ordinarily, there are two chief kinds of circuit connections. The first one is known as string connection.

Due to the electric current in each and every part is similar while voltage of the circuit is total of voltage in each component. Parallel connection is more complicated compared to show one. Unlike in string connection, the voltage of each part is similar.

It is because the element is directly connected to electricity supply. This circuit consists of branches which are passed by different electric current amounts. The current joins together when the branches meet. There are numerous items that an engineer needs to look closely at if drawing wirings diagram. First of all, the symbols utilized in the diagram should be accurate. It should represent the exact element necessary to construct a planned circuit.

After the logo is wrong or unclear, the circuit will not function since it is supposed to. It is also highly advised that engineer draws positive supply and damaging supply symbols for better interpretation.

Meanwhile, the negative source symbol is put under it.

The current flows in the left to right. Besides that, diagram drawer is suggested to restrict the amount of line crossing.Want to know how to wire your dual voice coil subwoofer or match the right kind to your amplifier? Read on to find out more. Dual voice coil speakers are extremely similar to single voice coil models except for having a 2nd voice coil winding, wire, and wire terminals.

They produce sound when a musical signal is supplied. Dual voice coil DVC speakers, which are most often subwoofers, are almost the same as standard single voice coil speakers. Single voice coil subwoofers have only one speaker voice coil winding while dual voice coil models have a 2nd voice coil of the same Ohm rating impedance added in the bobbin.

Power handling ratings are usually very similar always double-check to be sure but might be a bit different. These days, most car amplifiers have certain power ratings in Watts at a specific speaker load Ohm rating.

For example, a mono amplifier might have the following power ratings:. A 2 ohm DVC subwoofer could be used and wired in parallel to allow the amp to put out its full power.

As I mentioned earlier, not all amplifiers can be bridged. How can you add a subwoofer and supply it with enough power without having to buy a second amp? With a dual voice coil subwoofer, you could use one channel for each of the voice coils to drive the subwoofer with enough power. The rest is relatively easy! Then pick the right number of dual voice coil subwoofers that can be wired to match that required by the amp. Click here to download the.

Hi Marty my name is Troy and I have a question for you I inherited some kicker 10 inch subwoffers and I am curious on how to wire them. Hello Troy.Most car amps today have a minimum of 2 ohms per channel in standard stereo use and 4 ohms minimum when bridged.

Your amp will run hot and possibly become damaged. Amplifiers are designed to handle a minimum speaker load. Speakers are usually connected in series or parallel well, really, most often in parallel which affects the total resistance an amp will see. Always be sure to check to be sure. This is the first and best choice for most modern 4 channel amps.

Shown: An example of how to measure speaker impedance Ohms with a multimeter. Partly due to tradition in the electronics world and partly due to various other electrical reasons car stereos are commonly rated at 4 ohms and home stereo speakers around 8 ohms. The good thing is that all you really need to know is roughly what the resistance of a speaker is.

If you can measure that you can tell what Ohms rating to go by! If in doubt, you can rub them gently with a bit of sandpaper or even scratch the meter probes against the terminals to make better electrical contact. Car and home speakers are rated by their general Ohms impedance rating. For example, 2, 4, and 8 ohm speakers are never measure exactly with those Ohm measurements.

It will be in the general range and close to its advertised rating, however. Bridged mode is a flexible way to get more power from 2 channels in this case the rear channels, for example. Shown: High power resistors that can be used with a 4 channel amp when adding more speakers.

Power resistors are larger versions of the resistors used in many electronic products. However, if we add one 4 ohm power resistor in series with each speaker we can use the math to our advantage. You can use an L-pad speaker volume attenuation site like this one here to calculate resistor values for you. I recommend about 60 Ohms as it will give a volume reduction of 24dB. The problem with option 2 is that subwoofers need a lot more power to drive them well and sound good.

That way you can safely drive each channel with a 4 ohm load even older amps can handle. You can still connect a head unit car stereo with only 2 channels left and right to a 4 channel amp easily. In most cases, you only need 2 RCA Y adapter cables.
