Tech Talk Tuesday: CCA vs OFC Wiring — Why the Difference Matters
Ever see a cheap amp kit online and think, “Wow… that seems like a steal?” Sometimes the savings come from the wiring.
Today we’re breaking down CCA (Copper Clad Aluminum) vs OFC (Oxygen-Free Copper) wiring and why the type of wire in your system affects:
⚡ Power delivery
🔥 Heat buildup
📉 Voltage drop
🔊 Audio performance
⏳ Long-term reliability
Here’s the quick version:
CCA:
✔ Lower upfront cost
✔ Can work for smaller systems
❌ Less efficient
❌ Runs hotter
❌ More voltage drop
OFC:
✔ Better conductivity
✔ Cooler operation
✔ Better for larger systems & bass setups
✔ Longer-lasting performance
Both technically work… but one struggles a whole lot less under pressure.
Watch this week’s Tech Talk Tuesday to learn whether paying a little more upfront could save you headaches later.
