In actuality, the current has far more of an impact than the power. If the power was 500w at 8 ohms, 16 gauge wire might be used. If 500 watts at 0.5 ohms, 10 gauge is what you need. Otherwise, a suitable conventional wire size for subwoofers is 12 gauge.
The most common uses for 4-conductors are to deliver an amplified stereo signal to a stereo volume control or to two speakers that are close to one another.
Twelve voltsIt is crucial to remember that speaker wires are not intended for use with high voltages. Speaker wire is only appropriate for low voltage (12 volt) applications.
In addition, these cables fold and bend more readily than circular audio cables and are easier to handle and store because they don't tangle. They are more dependable and durable due to all of these attributes.
Connect speaker wire ends to test leads. Attach one lead to the battery's positive terminal and the other to its negative terminal. Look for any buzzing or humming noise coming from the speaker wire. Replace the speaker wire if no sound is produced; it can be broken or have a bad connection.
The wire gets smaller as the number increases. For better power handling, you might choose to use 14 or 12 gauge wire if your stereo has a lot of power. With high power amps, smaller wire, such as 16 or 18 gauge, can become heated or warm. Quality and wire size are two very different attributes.
In contrast to certain parts, including vacuum tubes, cables do not [wear out." Most of the time, a cable will continue to function exactly as it did when you bought it, barring damage or wear from being coiled/uncoiled, stepped on, tugged, twisted, bent, or subjected to other abuse.
Most Typical Speaker Wire GaugeBecause 12-gauge wire is thicker and has less resistance, it can be used in systems that require a lot of power or for longer cable runs. An excellent general-purpose choice that works well in most circumstances is 14-gauge wire.
In a living room or nearly audible in a stadium, a 100w speaker with reasonable efficiency that is powered by a well-matched amplifier and supplied with a proper signal would be unbelievably loud.
