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.

Nice thick ofc. Had plenty of wire. Holes were a bit small, had to drill them out a bit. No big deal. My 4 stars is for the cheap zip ties they included. Every one of them broke easily. Order zip ties if your ordering this kit. Overall, happy with the purchase. Stabilizing my voltage nicely

Great quality. I was amazes at how good this product is. Only thing bad was the tiny screws. Everything else was grade A too notch quality. Wire is bigger than my 1/0 Stinger wire.

Very happy with the size of the wire, some companies have smaller 0 gauge than others (idk how that’s possible) anywho, this kit was great and I actually had to cut the wires and ended up with enough left over to run a SECOND big 3. Just need to get ring terminals for it. Overall, amazing kit for the money, definitely helped my alternator support my 1500 watt system

Great kit for the big 3 upgrade. Heavy duty and easily flexible.

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.

I liked that the cable was very flexible. For my application on a compact 2 door I had a few feet of wire left over. I used the materials that recoil gives you to install the big 3. I will be buying another one of these in the future.

For how thick this wire is it routes and bends easily, and I didnt need anything else in addition to this kit aside from some new battery terminals to get a nice Big 3 completed. Will buy again for my other vehicle.

With it having a 6 and 2-4 wires to use its more than enough to get this done. And at the price it costs 30% to 50% less than others. I bought my rings at down4sound all of them for 10$.

Really happy with the quality price and turn out!
