KnuKonceptz Kolossus Flex Kable 4 Gauge Power Wire Red OFC (Sold in 5 Foot increments)

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!

Good quality and great reviews from other users. Flexible and packed full of ofc copper.

I love this cable! You can see and feel the quality all around. I especially love that it's flexible and easy to work and manage for whatever project. I highly recommend this cable without question.

Very nice wire very flexible can’t want to put some power to it

Great stuff! I needed to run a bunch of wire through my truck's frame and this stuff did the job. It's true 4AWG, the jacket is solid, it's high strand count (so it flexes really nice) and it's REAL COPPER. It solders like a dream too. And at $1.55\foot (when I bought it) it's cheaper than anything else out there! Will be buying from them again!

Super impressed - The wire is holding up just fine, solid current flows.

Very high quality cable looks nice. The insulation was damaged by my solder job when I got the wire a little hotter then the previous solder job that I did with the same cable, my solder gun is small used for electronics. I was using my solder gun's largest tip when the cable next to the solder job became too hot and tore and curled. It was no big deal, only 1/2" of insulation was damaged, I trimmed it and put shrink wrap over it. But this does not seem right, quite a low temp for heat damage to occur, so I took one star way.

My KnuKoncepts wire was stuck an hour away and I couldn't to a human in robo phone app to explain. Told KnuKoncepts my issue and next day, carrier claimed they lost it. My project is two weeks behind schedule, but KnuKoncepts got things moving again. I appreciate their diligence.
