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

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!!

Its a great cable! It's heavy and thick. The cable is very flexible and can be snaked into/through any area. I used it to install a 1000 watt power inverter in my van. Works and looks great. The outside covering has soft and rubbery feel. It has a pretty good rating to withstand temperature, but I still bought some plastic cable/wire cover to protect it in the engine compartment. I highly recommend!

After researching and comparing 0 gauge wires online, KnuKonceptz came out on top. These wires have the highest strand count of oxygen free copper, and don't try to trick you with thick insulation. Even though they are thick, they are incredibly flexible. While not the cheapest, these KnuKonceptz Kolossus wires offer the best value for your money.I would definetely recommend this product and plan to purchase again to complete my big 3 upgrade with a high output alternator.

This was used to relocate battery in vehicle. Copper coated aluminum wire made too much resistance over 60". Thistin coated copper wire fixed resistance/heat issues.

this is great wire however as soon as you cut it it starts to expand even before the casing is striped, the more you mess around with the wire the more it grows and can become difficult to get into any kind of end for crimping or soldering.

By far the best wire for the price. Heavy and flexible.

I needed some extra 0 gauge for an install I'm doing. The primary amp kit is NVX, this extra wire is so I can hook up a battery isolator, additional battery and a capacitor along with 2 amplifiers. I plan to use KnuKonceptz for full installs in the future. This wire is crazy heavy and every bit as flexible as the NVX wire. The insulation is not too thick (like cheaper brands) but still rugged with a nice silicone-like feel. I can't wait to start working with it in the install. I bought both the black and the red, they are both equally flexible and heavy!

Works great
