Rember this rule: never take chances with speaker wire length – don’t guess. Buy at least a little bit more than your estimate. Copper-clad aluminum vs copper speaker wire For most low power home or car speakers (not subwoofers) 18 gauge (18AWG) is fine. 18AWG wire is good for about 50 watts for 4 ohms and 100 watts for 8 ohm loudspeakers up to 50 feet (15 m) or 100 feet (30 m) respectively. Mark the length, then measure it. I like to add at least 1 foot of length for each wire section for home stereo use and 2 feet each for car stereo installations to play it safe. Figuring out how much wire to buy As you didn’t include the speaker impedance (this is very important!), I gather it’s 4 Ohms based on the 16AWG result you referred to. I’ll go through this example and validate it using an engineering approach.

However, I’ve made it easy for you: You can use my speaker wire size calculator or speaker wire size chart sections provided below. SPEAKER WIRE GAUGE CALCULATORBe sure to try to take curves & bends into account but don’t worry about getting it exactly right. Measure the distance and then add a few feet (an extra 2 feet or so is good) to account for curves and other little things that add up. Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now. Thin wire such as 20AWG or 22AWG isn’t very common but occasionally can be useful for lower power speakers. Stranded vs solid conductors Buying & using speaker cable is definitely one of those cases where the old advice “better to have too much than not enough” applies! You don’t want to run out because you didn’t plan ahead. No, oxygen free pure copper wire will not deliver any noticeable improvements in sound or power. It’s not worth spending more money on it.

Overwriting your speakers may lead to melted wires or even burning the wire inside the speaker. And lastly, if you have a warranty, always follow the warranty guidelines stated by the manufacturer. Marty is an experienced electrical, electronics, and embedded firmware design engineer passionate about audio and DIY. He worked professionally as an MECP-certified mobile installer for years before moving into the engineering field. gauge speaker wire can handle up to 100 watts per conductor, which is more than enough to power most speakers. Most speaker wire sold today is made up of two conductors attached as a pair with one marked as the positive; they’re essentially the same as stranded power cable paired together. The gauges available range from about 20 gauge to 10 gauge, with 18 gauge being one the most popular. For instance, what the amplifier has strained to achieve, the For instance, what the amplifier has strained to achieve, the speakers might undermine due to the type of speaker wire and the quality of the transmitting cable elements.
Solid core wire isn’t easy to deal with in situations where you’ll need to go around curves like around car seats or tight spaces. How much wire do you need? A 16 AWG wire has a diameter of 1.29032mm, translating to a cross-section area of 1.31mm2. The cable will offer you 22 maximum amperes for chassis wiring and 3.7 maximum amperes for power transmission. The breaking force for 16 gauge copper wire is 75 lbs. Stranded wire has a big advantage over solid in that it’s very flexible and not prone to breaking under stress. It’s also easier to strip the insulation to bare wire with a wire stripper. It’s also easier to work with if using spade connectors or inserting it into a crimp connector. You can use the 16 AWG to power high-impedance speakers (8 ohms) over shorter wire runs (less than 50 feet). Additionally, they are affordable for short runs during indoor and underground wiring. Longer speaker runs for car & home stereo speakers or short runs under 20 ft for 75-100W. Moderate power subwoofers (under 225W) with short lengths.

Most sound systems today come without a cable to transmit audio signals from the power amplifier to the receiving speaker. Although this presents an excellent opportunity to add a personal touch, choosing the right speaker wire can be a little hectic. Power, current, voltage, are critical for calculating wire size we need for any type of electrical load – including the speaker Ohms load. This is one reason why power companies can use high-voltage power lines to distribute thousands of Watts using smaller wire gauge while reducing wire cost power losses over long distances. It is true, however, that real copper wire is better than copper coated aluminum wire as I explain later. What gauge is speaker wire? (Wire size and wire gauge explained)Speaker impedance refers to the resistance to the flow of a current. A lower impedance rating means electrical signals in sound can pass through the speaker with ease. Unlike pure copper wire, copper-clad aluminum uses an aluminum wire core with a thin copper plating. From the outside, it misleadingly looks the same because of the plating. Why it made the cut: This GearIT wire is our top selection for outdoor use because it has a UL CL3 rating and is approved for direct burial. You may have heard of the skin effect in some conductors which becomes more of an issue at higher frequencies but that’s well above the 20 to 20kHz audio range so it’s not something to worry about.

Gauge vs. 14 Gauge Speaker Wire: Which is Better? 16 Gauge vs. 14 Gauge Speaker Wire: Which is Better?
Overall, a 14 gauge speaker wire is a great choice for audio applications because it offers increased flexibility and durability. It’s perfect for use in high-performance setups, Shea. ConclusionAlso, a 14 gauge speaker wire should be used to connect an 8-ohm speaker within a distance of up to 80 feet whereas a 16 gauge speaker wire should be used to connect an 8-ohm speaker within a distance of up to 48 feet. You raise a great point, Rodney, so thanks for the comment. I’ll need to mention something about using that type of wire outdoors and for marine use for that reason. Unlike the 16 AWG, the 14 AWG speaker cable seeks to prevent loss of power within long wire runs. This gauge is efficient when used in high-power applications such as 2 or 4-ohm subwoofers. You can use 14 gauge speaker cables for various audio solutions ranging from digital audio and stereo speakers to home theater speakers. In the simplest terms - 14ga is the default and serves a vast majority of people, Amps, and Speakers. If everything works as planned, you should be able to hear sound coming from the speakers. If not, you may need to increase the wattage of the speaker wire by adding more strands together.
