KnuKonceptz Kolossus Flex Kable OFC 0 Gauge Power Wire Copper Cable Black (50 ft) 1/0 AWG

Kolossus OFC is a must for anyone serious about their system. I originally purchased 4ga power and 12ga speaker wire a few years back and have been loyal since. It's flexibility is amazing and the quality is as the same or better than the two or three other top brands. The amount of copper in these 0ga wires is something you have to see for yourself. As someone who has been into Car Audio for over 30 years, I appreciate a product that aims to overachieve rather than sell out.

I used this knukonceptz 1/0 gauge silver tinned OFC copper wire to connect a second battery in my trunk to my first battery under the hood and also to run a second ground and power wire from alternator to main battery under the hood . It's been working great for a year so far through 120° temperatures in the summer to 10° temperatures this winter. Really helps reduce voltage drop when your car audio is pulling alot of amps . I would highly recommend this as it is a really good value for price per weight in copper.

I was skeptical but when I got my hands on this stuff I was highly impressed to say the least. This stuff is great quality, thick not from the jacket but full of wire strand. So much wire you have to finesse to get it all inside the lug. Flexible enough to work with and color is cool and vibrant. I intend to purchase more to finish my build in my car and highly recommend.

Let's face it, copper isn't cheap, but I will not comprise with the cheaper copper-clad aluminum. Using for my higher-wattage care stereo amp install and sure this will fit the bill

Very nice wire. Bought 25ft of 1/0 wire for my car stereo, extremely flexible! Thick blue coating feels good in hand and 100% OFC is always good! 👍

Its not cheap but well worth it.. A piece looked melted. Upon further inspection seemed fine. That is really wierd

Awesome wire.heavy,flexible,clean and even packaged discretely even tho it wasn't an option.ty knu koncepts.

This 0 Guage is top class. I bought this to upgrade my audio system’s wiring and I’m glad I did. This is a top quality product and it deserves more that 5 stars.
