Nice cables, thick
Size: 25FT, Color: Black+Red+Blue+Brown
Great quality, but due to being CCA those won't fit most 10awg crimps, will need 8awg crimps.

Good quality wire!

For the price this can’t be beat. Wiring is nice and flexible. Copper is solid. Amazing value and quality compared to what can be bought in the auto parts stores
