GS Power 18 Gauge 200’ Red /200 Black (400 feet Total) Bonded Zip Cord Speaker Cable for Model Train Car Audio Radio Amplifier Remote 12V Automotive Trailer Harness LED Light Wiring

Copper wire A+

It was the perfect wire for what I needed

Very poor quality.

This wire is TERRIBLE. I didnt read carefully and did not notice it is aluminum. It is fragile and difficult to make a reliable connection. It is also not AWG gauge. Amazon has real copper wire in AWG ratings for just a little higher price -- WELL worth the money.

Works very well light new wires

If you dont need a large amount, this is good wire for a good price.

This wire is aluminum. It will not carry current like 18gauge copper. CCA means Copper Clad Aluminum. Returned.

Cant beat it for the price. Time will tell how the insulation holds up but seems to be good quality. Allowed me to move/extend some harnesses and maintain wire colors.

UPDATE 12/1/19 - My first review about this wire was pretty negative. I was upset that I had to rebuild a wiring harness that I used inside a generator where there was lots of vibration. Now I use this wire for harnesses that are not inside the generator, but run to the control panel. So it has its uses, just be careful where you use it.

I used this wire to wire a controller in an ip68 enclosure. After a years service we are experiencing high oxidation of the conductors, this is an indication that the CU purity of the wire is low.
