What Is an OFC Wire?
OFC (Oxygen-Free Copper) wires have become a popular choice among audio enthusiasts looking to enhance their car’s sound system.
OFC wires, also known as oxygen-free high conductivity (OFHC) wires, are a type of electrical wire made from pure copper that has been processed to remove any impurities and oxygen.
This processing results in a greater conductivity than regular copper wires, which is why OFC wires are often seen as an upgrade for car audio systems.
Characteristics of Copper Wire
OFC wire is characterized by its high conductivity and low resistance. This means it can transfer power more efficiently, resulting in a clearer and more powerful sound.
OFC wire is also lighter than traditional copper wire, making it easier to handle and install in your car’s audio system.
How to Tell if a Wire is OFC
If you’re unsure whether a wire is OFC, there are a few ways to tell.
One of the easiest ways is to look for a label or stamp on the wire that indicates that it is OFC.
Another way to tell is to look at the color of the wire. OFC wire is typically a brighter and more uniform color than traditional copper wire.
OFC Wire vs CCA Wire
CCA wire is a type of wire that has a layer of aluminum at its core with a thin layer of copper on the outside. CCA wire is less expensive than OFC wire, but it also has lower conductivity and higher resistance, which can result in a less clear and powerful audio output.
CCA vs. OFC Resistance
OFC wire has less resistance than aluminum wire, so it can transfer power more efficiently.
This results in a clearer and more powerful sound and less resistance in the wire. OFC wire is a great choice for many audio systems because it is able to deliver a clearer and more powerful audio output.
What is CCA Wire Used For
CCA wire is typically used in systems where cost is a major concern, as it is less expensive than OFC wire.
Aluminum wire is also used in some car audio systems, although it is not as good as OFC wire for delivering a clear and powerful audio output.
Benefits of Using OFC Wire for Car Speakers
Improved Sound Quality
One of the main benefits of using OFC as car audio cable is that oxygen-free copper has a greater improved efficiency. This is because pure copper wire has a higher conductivity and less resistance than aluminum wire, so it can transmit more current to the speakers without generating too much heat.
This results in a clearer and more powerful audio output, making for a more enjoyable listening experience in your vehicle.
Another benefit of using solid copper as speaker or power cable is reduced resistance. OFC wire has a lower resistance than CCA wire, which means that it is able to transfer power more efficiently.
This makes OFC wires a more reliable choice for your audio system.
Durability and Longevity
In addition to its sound quality and power transfer benefits, OFC wire is also a durable and long-lasting choice for speakers or subwoofers.
OFC wire can withstand high temperatures and is less prone to breakage than CCA wire, making it a more reliable choice for your speakers or amplifiers.
How to Choose the Right OFC Wire for Your Car Audio System
When choosing pure copper wire for your car audio system, you need to consider the gauge size.
The gauge size refers to the thickness of the wire, with a higher gauge number indicating a thinner wire.
A thinner wire will have less resistance but may not be able to handle as much power.
To check the gauge size for your system, use this calculator.
Length of the Wire
In addition to gauge size, you also need to look at the length of the wire. Choose a wire that is the right length for your connection, and I suggest you do not cut it too short.
You will do better with an extra foot than when you miss one or two inches.
Type of Connectors
The type of connectors used on the wire is also important, as some connectors are better suited to OFC wire than others.
In quality systems, you may use gold-plated connectors to reduce voltage drop, but this will not be required in most installations.
Brand and Price
Finally, when choosing OFC wire for your car audio system, look at the brand and price.
There are many brands of OFC wire available, but my absolute favorite ones are Knukonceptz Kollosus for power and Knukonceptz Kord for speakers (links to Amazon).
