Most of the time, a larger size amp may require a dual power wire connection. What Gauge Wire For 8,000 Watt Amp is Best? When the connection length required in your application is too long, then it makes sense to use a much larger wire gauge. Typically, a 16 to 12 gauge wire is sufficient to hook up your speaker to the amplifier. However, this size is a little too large for a standard amplifier setup. How Many Amps Does an 8 Gauge Speaker Wire Handle?Īn 8 gauge wire can support loads of up to 40 amps. In this case, if you need a wire for more than 10 ft using the same amp rating, you can use a wire gauge of 1/0 or 2/0.
However, this wire should be in 4 ft applications for 2000 watts class AB amp under 50% efficiency. Normally, you can find 4 gauge cables that hold up to 150 amps. The answer to this question depends on the length of the wire.
If you use it to power your car audio, it is suitable for medium-sized amps or those with a total RMS rating of up to 1000 watts.
4 GAUGE SPEAKER WIRE UPGRADE
This will provide your electronics with a good power supply and is really beneficial, especially if you intend to upgrade your device in the future.Īs stated above, the wattage rating of a wire depends on the circuit. In this case, a 4 gauge wire bigger than 8 gauge wires will result in lower voltage drops. Using a larger size of wire is always preferable, since it offers less resistance than a smaller one. You may find online an actual size wire gauge chart showing 4 gauge with sizes of 5.190 or 6.720 mm (solid for the former number and stranded for the latter). A solid wire is smaller than stranded wires. Note: The diameter may change a bit depending on the type of wire you use. 8 gauge is often too small to boost a dead battery. Moreover, 4 gauge is more common in jumper cables. For instance, the size of 8 gauge wire can hold 35 amps at 19 feet, but to transfer the same load at 22 feet, a 4 gauge cord is better. In general, aside from the difference in diameter, 8 gauge and 4 gauge don’t carry the same load. This means that an 8 gauge power wire for amp with an RMS rating of 500 watts is best to deliver the latter’s potential sound quality. When used in a 12V circuit, 8 gauge copper can handle an average of 480 watts, but in a 24V circuit, it can hold 960 watts. However, depending on the circuit voltage rating, it may be able to handle a wide range of device wattages from 480 to 9,600W. It is best to use on a 40 amp circuit in most cases. The 8 guage wire diameter is 3.264 mm or about 0.12 inch and is suitable for powering low-powered electronics. In this scenario, let’s go through these wire sizes in greater detail below. Depending on the amp’s rating, these wires can be either 8 or 4 gauge. Most low to medium power amplifiers utilize two wire thicknesses for their power input. For example, when setting up your car audio, you must be specific regarding your wire amp kit. Wires are typically responsible for allowing a device to run safely and at peak performance.
