KnuKonceptz Kolossus Flex Kable OFC 4 Gauge Power Wire Copper Cable Black (15 ft) 4 AWG

Best quality of flexible wire you can buy and trust. Always buy this brand. Don’t waste money on CCA or cheaper crap.

I love this wire. Holds strong and clean current flow. More wire strand than skar 1/0 and very flexible. Can handle up to 375 amps of power. I use this in every vehicle for power and ground wire. True 1/0 specs and ofc wire.

I only use knukoncepts cable. Excellent quality

Used in a Audio system in my truck. Flexible and very good quality OFC.

Used to power my in-car amplifier. No issues.

Gonna start off by saying that my setup now uses various KnuKonceptz wires exclusively. I was using garbage 8 guage wire for my 600W RMS setup (Alpine MRV-M500, 2 - 12" Infinity Kappa Perfect Sub) and while moving my setup to my new car, I realized that the cores were burnt and thought there may be something to this OFC/OCC large guage recommendation. Still not fully sold on OCC over OFC in terms of end point sonics so whatever. So I bought all new parts from the battery terminal, HU, KnuKonceptz Kolossus Wire, ground block terminal, distribution block, and amp to redo everything better and right.Compared to the price on some of the other options out there, this is a steal! I don't have a micrometer but this wire is thick and has a crazy amount of strands. Not going to count, but I can only assume this is true 4AWG based on what the other reviewers have said. Whatever, it's at least 4 times as thick as my crappy 8AWG.The wires are semi-translucent and have a really interesting "rubbery" feel to them. I figured the heavy guage would make this pretty rigid but, I found it to be pretty flexible. I grabbed some 4AWG terminal ends and shrink wrap from amazon as well cause I hate how those amp screws never hold the wire right. Threw those on the ends, soldered them in place (make sure to use a heatsink, aluminum foil works fine, or the wire sheath will melt), and threw some heat shrink to complete the look. I couldn't be happier with how these came out! (well maybe a better soldering/heatsinking job, but that's whatever...)I now have them running:• Battery terminal block to the distribution block mounted in the trunk (+)• Trunk distribution block to amp (+)• Trunk ground block to amp (-)Can't say if these wires will hold up as I just finished the install today, but I really like KnuKonceptz as a brand because their products seem of good quality. I use their twisted pair wire between my amp and subs & inside the sub box I made between the sub and terminal cups. It could be a placebo effect or a means to justify the spending, but I think my system sounds better as well (could be the fact that my old wires were burnt and reducing the current, so yea, I'm sure these did something). I'm into clear, accurate, transparent sound and these helped my system deliver!

This oxygen free copper power cable is the real deal. I have purchased multiple times from this seller, and I've never had any issues with their products, and highly reccomend them.

I like the fact that your company's tinned OFC wire is great quality but yet you guys sale it for a reasonable price. All these other companies that sale wire that is similar charge 30-40 percent more per foot than you guys do. Why cant companies charge what you guys charge and be content. If your company can sale it at your price then other companies can too. Just goes to show where some people's hearts are. Make a decent profit, give the consumer a good price on a great product, and be looking forward to the customer coming back to do more business. I've never wrote a review aside from this one. Thanks guys. Look forward to do more business. Peace. Be well. God bless
