Features

  • 5145 Strands of Tinned Oxygen Free Copper (OFC) Tin provides a protective barrier from oxygen to the bare copper underneath. By adding a thin layer of tin to each strand, the cable is no longer able to oxidize making the Kolossus Kable more durable than bare copper cables.
  • Exceeds American Wire Gauge (AWG) Standards - The gauge of stranded wire is determined by the total area of the conductor. All KnuKonceptz products meet or exceed AWG specifications.
  • Ultra Flex Matte Soft Touch PVC - Our cable is ultra flexible making it easy to navigate tight spaces and maintains exceptional resistance to abrasion, oil, and extreme temperatures.
  • Kolossus Battery Cable applications include Battery Relocation, Big 3, Car Audio, General Automotive Wire, Truck, Solar, and Marine Power Cable.
  • Available in a variety of Pre-Cut Lengths

    • Best power wire for the $$$
Size: 20 Feet Color: Red
This wire is off the chain 5,145 strands of pure oxygen free copper. Researched every kind of wire and kept coming back to Knu Konceptz. You won't believe how big this wire is better have some good wire cutters!!! Best power wire quality and price!!! Got it running from my alternater, to my D3400 xs power battery under my hood, all the way to the D1200 xs power behind 2nd row seat, straight to mono amp and distribution block catching my 4 channel amp. System has 2 American Bass 10" xfl 1000 watts RMS EACH, planet audio BB 2000 watt RMS, alpine type R 6.5 front, Polk audio 6.5 rear, kenwood tweeters front pillars, with kenwood 4 channel 500 watt RMS.

Size: 20 Feet Color: Red
Bought the 20ft version to connect my alternator positive to battery. I have a 2006 saturn ion which has the battery in the trunk. 20 feet was the perfect size and it's true 0 gauge. Highly recommend

    • Silver tinned is the way to go.
Size: 20 Feet Color: Red
This stuff is great, really easy to work with, the protective layer is thick, but reasonably easy to cut. This is silver tinned, which originally I was against. But after seeing the oxidation on my 100% copper runs I new I needed a change, they are tinned with silver because silver doesn’t oxidize. No more voltage drops! ... show more

Size: 20 Feet Color: Red
Considering what similar cable goes for from other brands, I'd consider this a good value. These are HUGE and I'd recommend good crimping tools and soldering. I used a big pair of vice grips before soldering and it worked good. I've seen others use a bench vice, but I don't have one, so I used what I had and these aren't coming apart. I AM a little concerned about the thickness of the jacket. It is a little thin, IMO, for using in the engine compartment, but I'm going to use some wire loom to protect at least the positive leads, but I'd definitely pay attention to routing. I'll be going back for more later. ... show more
