GS Power 100% Copper 10 AWG (American Wire Gauge) OFC Wire. 25 FT Red & 25 FT Black Bonded Zip Cable for Car Audio Primary Remote Automotive Trailer Harness Wiring (Also in 6 & 8 AWG)

The red and black wires are solid copper wire, nicely joined together, but possible to separate the red and black without damage to either one. Looks to be a good product. Used for an extension of the wires on my electric trolling motor.

Nice quality power wire. Reasonably flexible for this heavy gauge.

Nice slick insulation great for fishing through existing wires.

Good wire, Im happy

It looks like solid copper, this wire was a good deal. Used it for long runs inside my car, I wouldnt use it for high temp locations (i.e. inside your engine bay) the coating is not designed for high temps.

I only subtracted a star because I feel this wire could be a bit more flexible, but Ill admit Ive long been buying multi-strand welding cable for battery work, especially in my campers. But this is good cable for running lines to low voltage accessories, especially in a vehicle, and its great o have the black-red leads zipped together without having to buy separate spools of wire. I specifically bought this to make a 16 foot run from the battery compartment to an outside 12VDC power port on the side of my camper, and it worked great.

UPDATE 10/2021:

We have been using these products in Solar systems for several years and have had great luck....

DC power distribution.

Nice wire. Seems to work just fine. I wasnt expecting the two wires to be fused together, so, nice touch.
