Can Speaker Wire Be Used For 12v Power? Ultimate Guide

It is inevitable that we will all end up with some speaker wire in our houses, whether it be from a previous setup or for some other purpose. And for many of us, the idea of a little old speaker wire lingering around can seem wasteful and wasteful. But has it ever occurred to you that you might be able to use this old speaker wire as 12V power?

Speaker wire is measured in gauge. The higher the gauge of the wire, the lower amperage it can handle. We will look at this topic in detail and then combine it with all other information to help you figure out if 12v can run through speaker wire and what else you can use it for

1. Is the speaker wire different from the electrical wire?

Speaker wire and electrical wire are the same things, as they share the same insulation material.

Wires come in various colors, which helps distinguish them while they are grounded and plugged in. The insulation is transparent, so the two wires can be plugged into each other for their different purposes.

2. Can I use speaker wire for 12v power?

The short answer to this question is “yes”, although the long answer is that it will depend on a few factors. For example, in the early days of audio equipment at home, the standard wire with which you would connect up your lamps was used to connect up speakers and amplifiers.

Table lamps, ceiling fixtures, and more are all standard voltage. Electrical devices that have a transmitter housed within them will be low voltage; you can use “speaker wire” to run 12v power.

3. Considering wire gauge

The diameter of a wire will determine its gauge. It will also influence the amount of electrical current that it can carry and how easily it resists the current. Wire gauge is determined by the American Wire Gauge system, which takes into account resistance as well as weight.

4. What electrical devices can be connected with speaker wire?

The only thing you need to account for when running electricity through the speaker wire is the gauge of the speaker wire. The wire’s gauge will allow it to carry a certain amount of electrical load based on a device’s wattage.

When you think of voltage, there are standard voltage and low voltage. Standard voltage is 120 volts, while low volt has a transformer that lowers the voltage to 12 or 24 volts.

Speaker cables can now be used as a source of power for low voltage applications in your home. Speaker cables are usually paired with speakers for sound, but they can also be used to provide energy to other devices such as thermostats, hard-wired smart home devices, doorbells, and garage door openers.

Always remember to convert the voltage in your outlets, depending on if you are in the United States or in Europe. If you are in the US, make sure your appliance is compatible with 120 volts. If you are in Europe, make sure that your appliances are either 240 or 220 volts.

You need to be able to calculate the gauge of wire you will need in relation to the wattage of the device you are connecting. Depending on what type of wire you use, it may overheat and start a fire!

5. How much power is through the speaker wire?

The gauge of the wire (speaker wire) will be different, depending on if you need it to handle higher or lower power. The gauge of the speaker wire (measured in watts [w]) depends on how much amperage it can handle per volts.

Watts = amerage x voltage

Let me give you an example. When you think about a garden hose, the stream of water that runs through it is the amperage. The pressure of the water coming out of the hose is the voltage.

Electrical devices take up a lot of power. You’ll have to pay for the cost of your devices even if they’re not in use.

The amount of power allowed to travel through a circuit will be determined by the size of the wire (gauge).

Thicker wires are safer than thinner ones. This is due to them being able to pass more amperage without overheating.

The chart shows the amps that different types of wires can handle; electrical wire, speaker wire- which is identical to the electrical wire- and things like staples below 12 gauge.

Wire Gauge Amperage

16 gauge 13 amps

14 gauge 15 amps

12 gauge 20 amps

10 gauge 30 amps

8 gauge 40 amps

6 gauge 50 amps

This is where we answer the question of whether or not 12v power can run through speaker wire.

Your speaker wire can run a 12v electric current, but it can only do so for specific devices. If you use the equation, electrical wattage = your wire gauge divided by the square root of 2, then you will be able to determine what your device needs in order to use electricity.

Suppose you have 16 gauge speaker wire and 12 volts running through it. If you wire it to 186 volts, then the speaker wire will be able to run a device that draws 156 watts of power.

Watts = amperage x volts

The 12 volts in our equation are for the speaker wire. To determine the amperage of the speaker wire we must take its gauge into account. The chart shows us that high gauge wire, such as 16 AWG, can handle a maximum of 20 amps of current.

16 gauge wire can handle 13 amps and all that.

Watts = 13 x 12

Watts = 156

A speaker wire should be able to handle the electrical load based on the wattage of your device, and the gauge of your speaker wire. This will be located on the sticker or in the specifications on your device.

Conclusion:

Speaker wire can be used for 12v power, but it is not recommended. The reason for this is that the speaker wire is not as thick as a standard power wire, and thus is not able to handle the same amount of current. This means that if you use speaker wire for your 12v power needs, you run the risk of overloading the wire and causing a fire. So while it is technically possible to use speaker wire for 12v power, it is not something that we would recommend.
