One of the best abilities you'll need to acquire is the knowledge of selecting speakers that match the appropriate gauge and length of speaker cables. If you rarely use your amp or stereo output above 50%-60% power, you can go down one wire AWG gauge. This is because you’ll never reach the wire’s current capacity if you don’t use maximum power.

The current flows through two conductor sides (positive & negative) for a total of: 2*4m*0.0147Ω/m = 8m*0.0147Ω/m = 0.1176Ω total resistance for 4m of 19/29 stranded wire.

It is based on its use. 12 gauge speaker wires are the best for long wire runs and high-power applications. Conclusion losses but they are secondary concerns to primary DC cable resistance. Although I have measured some exotic cables Aluminum has only 61% of the conductivity of copper (in other words, it has 39% more resistance) meaning it will take larger aluminum wires to get the same power handling, capacity, and resistance value. Likewise, each AWG wire gauge has an electrical current capacity (how many amps it can handle, also called ampacity sometimes).

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. between the amplifier and loudspeaker that all other cable parameters will become a wash. This article will Most of the greatest speaker wires are constructed of copper because of their excellent electrical conductivity. Searching for 100% copper-made wire for the highest grade wire is strongly advised. Is 12 gauge speaker wire best?Speaker Wires are the subject of ongoing controversy. To connect speakers to amplifiers, some people spend cheap cable. But even though speaker wires are pricey, some audiophiles conduct extensive studies to find the best-performing models. A tape measure works well and so does string or rope you can place along the path where the wire will go. A stranded wire has fewer issues when using spade or crimp connectors for inserting into speakers. Never connect extra electrical wiring from the house for the speakers, as it is not a good idea. FAQs Is oxygen-free speaker wire worth it? You may be confused about the speaker wire gauge to use for your sound system. The best option between 14 gauge and 16 gauge speaker wire depends on various factors including: This distance can be used to calculate the wire gauge required to get the best performance out of your speakers.

It is possible to run 4-ohm speakers up to 24 feet using 16 AWG wire, while 10 or 12 AWG wire is advised for runs up to 100 feet. For lengths up to 36 feet with 6-ohm speakers, 16 AWG wire is advised, and for runs up to 150 feet with 10 or 12 AWG wire. 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 For surround sound and center channel home theater speakers, you shouldn’t spend a lot because their power needs are usually fairly low. 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 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. Stranded speaker wire design 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

is a ratio of rated loudspeaker impedance (ZL) to the source impedance (Zs). In this case our source impedance is (Rcablecable resistance to drop the signal level down 1dB for an 8 ohm speaker. More importantly however, as the series resistance
