Review on Upgrade Your Power/Ground Setup: InstallGear 1/0 Gauge Red 25ft OFC Wire - 99.9% Oxygen-Free Copper by Matthew Bell

Damn good wire. Solid copper. Thick strands. I think it might be more than AWG size ratings. Gigantic. This is my second stereo. The first thing I got was an aluminum copper wire. And I had to buy another cable, it broke so bad. So I got 100% oxygen free copper. On Amazon. And none of those wires I just pulled out even come close to this wire. top shelf. Thick copper through. The only complaint is that I couldn't get a 30ft roll so I had to buy two 25ft rolls. But it was worth it.
