I heard that the ground cable was cca is that true?

When I purchased the kit in August 2017, both power and ground wires were OFC.

Several people say this is not true OFC that it's actually CCA. Who's telling the truth here???

The kit I purchased in July 2017 was definitely OFC copper cable, true 4 ga (NOT 6 ga with extra thick insulation to make it look like 4 ga). Maybe they switched to Copper clad aluminum sometime after that.....

Is this 100% ofc? i dnt want cca.

Yes, the ground wire is tinned OFC, the power wire is pure copper, 1911 strands. The speaker wire is also OFC, the RCA patch cables are OFC twisted pair. Grab some furrels and good copper 4awg crimp lugs and dual wall heatshrink for and good install

Oxygen Free Copper. Copper and aluminum are the most commonly used wire materials and there is a significant difference in quality, power handling and signal transfer between these materials. The least costly between these 2 options is Copper-Clad Aluminum (CCA) wire. CCA wire utilizes an aluminum core that is clad or dipped in copper. It is a suitable choice for lower powered systems or restricted budget applications, although the power transfer is not on the same level as the far superior Oxygen Free Copper (100% OFC) wiring. OFC wiring is refined to remove virtually all oxygen and other corrosive elements. it’s ideal for wiring, however this product is a little misleading. Not all of it is OFC.
