KnuKonceptz Kolossus Flex Kable 0 Gauge Power Wire Black OFC (Sold in 5 Foot increments)

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.

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!!

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.

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.

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 ….

Knu is a well known brand for car audio power wire, speaker wire, & rca cables. This is a high strand count, OFC, & when they say the size is 1/0, they mean it. You won't be disappointed. I've wired 4 vehicles with Knu wire, so far. The photo, was my 2017 Ford Fusion Sport, using 1/0 in orange.

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.

True 1/0 gauge wire as described, I will be buying this brand for all wire gauges from now on
