Assuming an 8-ohm speaker and discussing an audio power amp, the solution is to find the square root of 2000W divided by 8 ohms, or 15.81 amps. You would want a 10 to 12AWG with that. Longer wires and higher frequencies (because of the skin effect) increase resistance; depending on the application, a larger wire may be required.
Additionally, thicker wire transfers electricity to your speakers more effectively and helps to avoid power outages. Your sound won't suffer if your wires are thicker than necessary, but you might not hear a significant improvement either.
There are 4 Ohms of resistance in a 4 Ohm speaker. The speaker's frequency response may be made so flat because the inductive reactance is so small in comparison. Therefore, if both leads are coiled together, coiling them to the speaker will not have much of an impact.
All you need is 16-gauge wiring for most home entertainment systems. However, upgrading to 14-gauge isn't a bad idea if your speakers are farther distant from the receiver than fifty feet. Additionally, 14-gauge is the best if you're utilizing lower-impedance speakers or a high-current amplifier.
The ground, or negative, wire is usually black, whereas the positive wire is often red. But the majority of speaker wires don't support color. Fortunately, as long as you are consistent, it doesn't really matter which speaker you use as your positive and which as your negative.
The drivers simply push out rather than pull in when the red and black speaker wires are switched (and vice versa). The drivers of the other speakers in your system will be operating in an entirely different (absolutely opposite) direction when they are producing the same sound.
The four-conductor cable for speaker one has the following color codes: Red (positive), Black (negative), White or Yellow (positive), and Green (negative).
What is the lifespan of speaker wires? The speaker wires may last for several decades, provided they are not subjected to severe temperatures, moisture, or physical harm. Since I've owned my speaker cable for so long, I haven't seen any problems with signal deterioration or anything else.
A speaker wire's voltage is determined by the power of the amplifier; for example, a 100-watt amplifier per channel will have a voltage of roughly 30 volts RMS.
The thickness of 16 gauge steel is.065" inches, or roughly 1/16th of an inch. In contrast, the thickness of 14 gauge is.083 inches, which may not seem like much, but it is about 30% thicker (27.6% to be precise).
