It says oxygen free on the package but when I got it my cables are all copper clad aluminum lower quality and not what I paid for I basically paid about $30 more for something that shouldnt have been so expensive seeing as I was given the basic product. I will not be ordering from this company again Im just going to stick with skar audio. At least with them I know that Ill be getting quality products and I will get the correct order that I paid for.

Great wire and I had more than enough to do the big 3! It significantly helped my electrical output to my amp!

Perfect kit for big 3 upgrade. I have a 2005 stratus with no room in the engine bay. Well had plenty of cable plus some. System hits harder than ever. Cant wait for the 14v extra battery and cap upgrade to power a second Sundown Audio 4 channel amp.

Just as described. Cheaper than buying the parts separately. No more lights flickering because of my system

Worked great! Have had no issues. Good QUALITY

Only complaint is the insulation sleeve on wires is a bit whimpy but they do the job.

very flexible. very thick. 100% copper BUY IT

Really happy with the quality price and turn out!

This is a great kit. The wire is high quality and flexible and the connectors are high quality too.

Worked great for my big 3.
