The 8 Best OFC big 3 Kits (2023 reviews)

The knukonceptz oxygen free copper should be able to handle its purpose and duties with ease. The speaker wire is well made, and is more adequate for any runs you need to do. It has some pretty beefy wire and is flexible. The wires are nice and super flexible for the gauge size. The RCA and amp turn on wires are joined together making installation super easy. The wires are a lot more flexible as well.

The power wire is chunky and nicely flexible and the crimp-on spade connectors are solid and fit securely. This is a great buy for 1000watt systems and higher or if your looking to upgrade later on.

Why We Like This:

Terminal hardware is large and solid
Thick cable, easy to manage, highly recommend
Oxygen free copper is the way to go, spend the extra
Very soft and very high quality materials
