Carretel de 30 Metros Fio Vermelho Fosco 4 AWG

Took me about two hours to route this through the car, and the jacket is thick enough that I didn't worry about nicks near the frame. The 100 feet gave me plenty of slack to run a clean line to the amp with room to spare.

Spent the whole weekend running this frosted red wire through my trunk and under the seats, and the 100-foot length meant I didn’t have to splice a single join. The insulation feels tough yet flexible enough to route around tight corners without kinking. Multi-strand copper this clean at this price

The 4 AWG copper strands are thick and flexible, so routing it through my trunk was way easier than I expected. Cut cleanly at 100 feet with no kinks or frays in the insulation.
