Very nice heavy duty well built 100% OFC Copper wire. Do not settle for less. This particular brand cable has been installed in my daily driver for over 6 years. I just went threw an amp upgrade. The cable is still flexible just like the day I bought it. The setup goes from 0 gauge to a splitter where it has 4 outputs of I think 4 gauge. All cables are still like new with no cracking or deteriation. The cable does look like it has a few spots of mold but that's my fault.

First of all, the insulation is beautiful and the colors are super deep and rich, good for people who build pretty systems. I didn’t know pretty wires was something I required until I bought these. They’re super heavy and I bought all sorts of different sizes from 16 awg all the way to 1/0 awg and all sizes are true. Wires are super flexible and insulation is easy to cut. This is going to be what I use from here on out.

I have used many different brands and this is a very good one. Super flexible wire that is thick and good quality. The jacket is thick but not overly thick like Sky high or others I have used but the wire inside is just as big. So even though some other high end brands have a little thicker jacketing. That makes the wire stiffer so I like this stuff because it's easier to bend. The thickness and the amount of copper is top notch.

I purchased this wire (along with several other KnuKonceptz products) to relocate the battery in my car to the trunk. I am very impressed. First, the wire itself is extremely flexible - so flexible that it feels like picking up a wet noodle instead of a 0 gauge power wire. Running it was a piece of cake. Second, I ran nearly 15 ft of this wire in total, and had absolutely no loss of voltage or trouble starting the car. Combined with the other KnuKonceptz products (battery terminals, fuse holders, etc) the entire project was affordable, easy, and works perfectly. Super-happy customer.

This is by far, the best quality wire I have ever owned. Extremely fine strands and very heavy. The silicone insulation is top quality, and the price for this quality of wire is unbeatable, even after having to pay the shipping. My system consists of 1/0 gauge supply wire to dist. block and big 4 upgrade, 4 gauge subwoofer amp supply and 8 gauge supply to door speaker amp, 12 gauge wire to door speakers, 14 gauge to door tweeters, and 8 gauge to subs. All wire in my SUV sound system build is Knukoncepts excluding the RCA's, and that's only because they didn't have the lengths I needed for my configuration. I am ordering the power and "big 4 upgrade" wires for my work truck today! You will not be disappointed with this purchase!!

Why did you pick this product vs others?: I ordered 50ft of the 1/0 blue OFC and it was true 1/0 and just a little longer than 50ft which was great …. Now I would have given this product 5 stars but while I was wiring up my suburban the copper strands inside kept slipping in the rubber insulation. It would go either too far in or too far out …. It’s too loose inside the insulation! Feels like I was getting scammed on the amount of strands inside ….

Very flexible works well I got black and red to run a large inverter and it’s partially under a truck and is taking the abuse so I’m happy

Great product this is my second time getting some of this wire. Way better than that sky high stuff they trying to sell. Very dense material makes for a great product. My voltage numbers instantly went up when I took all of my old wire out and put this new wire in. I will Continue to purchase this kind of wire for my application needs.
