Description

Product Description The KnuKonceptz Kolossus 0 gauge amp kit features our top of the line Tinned Oxygen Free Copper Kolossus power and ground wire. Made up of ultra flexible PVC and ultra fine tinned strands of oxygen free copper (OFC), the Kolossus Kable is the standard for which all others are compared to. This kit is designed to be a base for installation of a large, high current audio system. Once again KnuKonceptz includes additional 0 gauge ground wire to allow for Battery to Chassis Ground. Included with our kit is one Inline ANL fuse holder with 300A Fuse. Additional Speaker Wire and RCA's will be required to complete your installation. Kit Includes: How many watts can this amp kit handle? At KnuKonceptz, we do not use "watts" to rate our amp kits. This is a very inaccurate method to determine what the proper gauge wire required for your amp installation. Many amp manufactures do not represent the output of their product accurately in watts. Please refer to your amplifier's fuse rating, this is a number a manufacture can not fake, well they could but it would put their product in harms way! Add up the fuses on the end of your amp (Three 80A fuses = 240A total draw) If this number is under 300A, this kit will fit your application. All KnuKonceptz Cable Products clearly state these specifications These materials are commonly used, but not commonly stated when shopping online. Know what you are purchasing. Both metals are capable of performing up to their rated loads. Wire gauge is crucial to powering your system correctly. Undersized cable will create unsafe conditions and may shorten your amplifier's life. Wire's ampacity changes with gauge and materials. KnuKonceptz does not rate cable based on watts. Amplifier manufactures do not always truthfully state the output of their product, check your on board fuses!

True 0/1 OFC

Definitely worth the purchase! Highly recommend!

The Standard for High Quality Wire, True 99.9% OFC 0 Gauge Wire Kit That Exceeds Expectations In Every Way
Color: Blue
There is not enough reviews on this kit so I am going to attempt to cover what needs said about KnuKonceptz Kolossus Flex wires. I am at a loss for words in regards to how amazing the KnuKonceptz Kolossus Flex wire series is and why there isn't 1 million 5 star reviews on this kit alone. After making a thread on a car audio forum I received many suggestions to upgrade my factory electrical wires aka the big 3. I have been through countless amp install kits in the past from multiple brands and I was beginning to think getting a quality wire kit was near impossible, until I found out about KnuKonceptz. The brand KnuKonceptz is THE holy grail of audio wires and is what everyone will compare real true gauge audio wire too. For starters this kit is exactly what it says it is. 100% True 0 Gauge Oxygen Free Copper with the ability to twist and bend better than the worlds best contortionist. When considering my big 3 upgrade I had spend a few days worth of free time trying to find the best deal when it came to wire kits and all I can say is this is what you need to get the job done right. Kits that are specifically for the big 3 cost about the same amount of money and contain roughly half of the wire you will need to get the job done. I own a ford ranger and I used every foot of this kit running wire in just my engine compartment, something that if I would have settled for a dedicated big 3 kit I would have been sol and would have just wasted my time and money. Everything in this kit is high quality even down to the black and red terminal sleeves. You can actually attach the ring terminals to the wire and slide the sleeve over the terminals all the way to the designated resting spot with ease. (I have never had a kit contain such quality components through and through like this) Some advice for when you buy this wire and go to install it. If you plan on doing the big 3 you will need an extra set of ring terminals. I purchased the frequently bought together terminals from KnuKonceptz and although they are the shown as the same thing the standalone terminals ring holes are actually a little bit wider than the included ones in this kit. For me this worked out perfectly as I was able to use the smaller hole terminals to get a snug connection to my alternator and grounds and the bigger hole terminals for a direct connection to my batteries side posts. (The optima brand and 99% of batteries out there that have side posts use the standard gm size bolts) If you do not have side posts on your battery you will need new top post battery terminals specifically for car audio that has 0/1 gauge input/outputs. Another install tip is when you go to install the 300 amp ANL fuse holder cut the wire where you want the fuse holder and immediately slide the screw on end pieces to both sides of the cut wire (do this before cutting the insulation down to expose the wire) I had to back track here because I just went ahead and screwed down each fuse holder terminal and assumed the end pieces would slide over top of them. This was not the case as the fuse holder is designed with rubber gaskets to make it near waterproof. Conclusion and Recommendation Buying any KnuKonceptz Kolossus Flex series wire kit will drastically change your outlook on what real wire should be when it comes to pure quality. I am so impressed with KnuKonceptz wire I will be removing every power and speaker wire I have installed and swapping it for Knu's equivalent. This company understands what proper audio installation is all about and the fact they include extra ground wire to upgrade your factory grounds to fully utilize the wire your using proves it that much more. Any other company I looked into charges you more for less, attempts to include all kinds of misc. install accessories to hide the shorter length wires, and even tries to withhold what kind of wire you are buying (CCA is garbage and cannot perform anywhere near OFC especially when it comes to electrical conduction) I recommend anyone out there looking for wire kits that are the real deal stop looking beyond this brand. Buy this kit, buy any OFC KnuKonceptz wire size you need, stop wasting your money on junk or overrated kits, and get to installing wire that will change your brand loyalty so quick you will want more just off of the principle of owning the best wire they make. ... show more

Game changer
Color: Blue
I had 4 gauge KnuKnoceptz OFC wire installed in my car years ago when I had a CT Sounds 1400 watt amp. No issues, until i stepped up to a 2500 watt Sundown amp. I started to pop fuses when i turned it up to higher volumes. I bought the 1/0 gauge OFC amp kit, and just the upgrade power and ground wire from 4 to 1/0 gauge, and it is a game changer. No more cutting off, or popping fuses. The amp kit came with more than enough power and ground wire, grommets, wire ties, battery connectors and even plastic wire loom. I am sure there is a wire brand out there that is better, but you cannot go wrong with KnuKonceptz. Highly recommended. 5 stars for quality and value. ... show more

Solid wire!
Color: Blue
The wiring is true 1/0 gauge and extremely flexible! This was probably the easiest wire I’ve ever had the pleasure of installing. 100% bang for buck it’s pricey but worth it! Only reason for 4 stars is because the fuse holder is trash. If they fix that, 1000% would purchase the kit again. Wire 100% I’m gonna order again but the kit with the fuse isn’t worth it. ... show more

I bought 8 gauge speaker wire by this same brand and they were great. Started having an issue with my cca power wire causing my amp to go into protect mode so I decided to upgrade to ofc and got this kit. I am really impressed with the quality and value. I love that they even included rubber gromets to put in the hole that runs through the firewall in order to keep the wire protected. And I like that this kit is just the power and ground wires since I don't need the speaker wires or RCA cables. Ofc wire gives you over 200 watts more power than CCA and I can definitely feel the difference. Sounds like my subs are trying to blow my gas cap cover off lol I definitely recommend this product! ... show more
