## Description

Product Description KnuKonceptz KCA 4 Gauge Complete 2 Channel Amplifier Installation Kit The KCA Kable (Kolossus Copper Aluminum) is the next generation of our Copper Clad Aluminum (CCA) power and ground cables. The new KCA 4 Gauge uses 29.44mm^2 of Copper Clad Aluminum (CCA) to transfer current from your battery to amplifier. Copper Clad Aluminum (CCA) is made up of 90% Aluminum and 10% Copper. The KCA 4 Gauge Kable used throughout this kit offers incredible flexibility and a rugged PVC outer jacket that is impervious to grease and oil. The PVC outer jacket can withstand extreme temperatures (-40 to 105 C). Kit Includes 5.4m 4 Gauge Red KCA Kable (CCA) Power Wire 0.9m 4 Gauge Black KCA Kable (CCA) Ground Wire Inline fuse holder with 80A fuse 5 Meter Bassik Twisted Pair OFC RCA Cable 6 Meter Bassik 14 Gauge CCA speaker wire 5 Meter Blue Remote / Turn one wire 2 gold plated 4 gauge ring terminals, 2 gold plated 4 gauge spade terminals grommets and wire ties Beware of "1600 Watt" amp kits that include a 50 or 60A fuse. Its physically impossible for these kits to support this load (refer to our comparison photo) Do not use on loads over 100A, for this we recommend the KnuKonceptz Kolossus 4 Gauge amp kit, which uses Oxygen Free Copper. KCA 4 Gauge - Oversized for higher loads vs other CCA cables Our Kolossus Copper Aluminum (KCA) series cable was designed specifically to be larger than the competition. Copper Clad Aluminum is less conductive than Oxygen Free Copper when comparing like sized conductors. CCA however is also much less expensive. So by increasing the area in our KCA cable, KnuKonceptz was able to achieve similar performance to OFC**, but without the higher cost. For this exact reason is why our cable is larger, to achieve similar performance, for less money. The graph below shows, based on area, our cable is at least 40% larger than comparable brands. **(as tested by Permornace Auto & Sound Magaizne) Plain and Simple Specifications Wire type - CCA or OFC 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. American Wire Gauge Wire gauge is crucial to powering your system correctly. Undersized cable will create unsafe conditions and may shorten your amplifier's life Max Load (amps ) 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 American Wire Gauge (AWG) Products Using American Wire Gauge standards, the gauge of stranded wire is determined by the total area of the conductor. To calculate this you would take the area of each strand and add it together. This area, in square mm, then determines gauge. Diameter is not as critical with stranded wire, this is due to the tiny air gaps between each strand. Diameter may fluctuate with strand size and how tightly wound the rope of the cable is. The smaller the number, the larger the wire, until you reach zero or aught (0). From zero, you then have double aught (00), three aught (000) and so on. Based on AWG, the true gauge of this cable is #3, larger than traditional 4 gauge Copper Clad Aluminum - Best Value Copper is the best conductor, however for value, CCA makes a great bang for the buck option. Proper termination is crucial for an increased life span. Always check that connections are clean and secure.

Review: easy to use, works well. - i'm no car audio installer but am happy with this product. all parts present in the pack needed to wire in an amp and sub, got mine wired into a navara no issue, cable is good and flexible, all the parts are easy to work with and yeah, it just does what it's supposed to, can't ask for a great deal more that that.
Review: Quality at its best!!! - Amplifier power and earth wire are the best you can get, packed full of metal with a nice thinner layer of insulation, the cable is easy to route and is very flexible, fuse is perfect as are the RCAs and the terminals are quality, please note there is no remote cable in this kit so you will have to buy it seperate, i have done quite a few installs and this is the best 4 gauge wire i have ever used, looks to be boarding on some lower quality 0 gauge its that good, by all means shop around but if you want the best bang for buck look no furthur!!!
