Although there’re numerous kinds of power cords designed today, it’s not advisable to use any power cord you come across with an amplifier. When connecting an amplifier to a power socket, it’s advisable to only use a power cord that’s specially designed for an amplifier. The reason behind this is that power cords differ significantly.
If you use the wrong cable with an amp, unwanted noise such as electromagnetic interference and radio frequency noise will find its way into the current. As a result, your audio system will output low-quality sound.

Factors to Consider When Choosing a Power Cord for Amplifier
If you want the best power cord for amplifier, then you should take note of the most important considerations to make. Considering there’re many brands to choose from, you may find yourself confused about the best option. Here’re some factors that can help you choose a power cable for your amp.
The length of a power cord is one of the most important considerations to make. If you’re setting up the amplifier in a large room and you want to place the amp far from the socket, then consider a longer speaker cord. However, if you’re setting up the amplifier near the socket, then you won’t have an issue with the cord length.
2. Wire gauge
Another important factor is the wire gauge. Wire gauge is measured in diameter and denoted by AWG (American Wire Gauge). The smaller the AWG value, the thicker the cable. For instance, a speaker cord with a wire gauge of 10AWG is thicker than the one with a wire gauge of 18AWG.
The best wire gauge to choose will depend on your amp’s power needs. If the amp requires a lot of current to power it, choose a power cord with a lower wire gauge value. If the amp requires minimal current to power it, then a power cord with a higher wire gauge value will suffice.
It’ll help to choose a flexible power cord. It should be effortless to bend it around corners since the location of the power port on the amplifier and the socket might require bending the cable. If the cable is too stiff, you’ll find it challenging to bend it around corners.
4. Type of connectors
The connectors on both ends of the power cord should feature a highly conductive material for maximum conductivity. Also, the connectors should be compatible with your socket and the type of power port on your amplifier. That way, there’ll be a tight contact between the cord, socket, and power port on your amplifier for uninterrupted operation.
5. Conductor material
A power cord features several wires within the shielding. Most power cords feature a copper conductor. However, the conductor material may vary in terms of the grade. For instance, higher-grade copper will offer better conductivity than lower-grade copper.
The cord should be made of top-quality materials. That way, you’ll be sure that you’re investing in a power cord that won’t fail any time soon. Also, the connectors should be tightly soldiered in place. They shouldn’t wobble.
It’s also important to ensure that the power cord is properly shielded. When properly shielded, the cord won’t be prone to electromagnetic and radio frequency interference. Consequently, you’ll enjoy improved sound performance from the amplifier.
It’s important to ensure you choose the best power cord for amplifier. With a proper power cord, there’s less likelihood of getting unwanted background noise from your amplifier. Failure to use a top-quality cable will cause noise in your music. Hopefully, our guide will help you find the ideal power cord for your amplifier.
