These cables are no Joke they are Beefy and Flexible. Talk about true 0 gauge. The quality I must say is really good for the price you wont find anywhere with good 0 gauge like this. Thank you Knukonceptz.

  • 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

  • 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. Stays at or above 14.4 volts at idol lights don't flicker either ... show more

  • The best
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

  • Love this company and brand
Size: 20 Feet Color: Red
Great wire couldn't be more happier. I have purchased multiple products from this company and very happy. There is a power wire showed on a video on YouTube by a guy named HiFi Vega and this wire did very well.
