Product Description

Product Description

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).

KnuKonceptz KCA 4 Gauge Complete 2 Channel Amplifier Installation Kit

The KCA-K4 Amplfier Installation Kit Includes:

  • 18' 4 AWG Blue KCA Kable (CCA) Power Wire
  • 3' 4 AWG Black KCA Kable (CCA) Ground Wire
  • Inline fuse holder with 80A fuse
  • 5 Meter Bassik Twisted Pair OFC RCA Cable
  • 20 Feet Bassik 14 AWG 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

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 (two 30A fuses = 60A total draw) If this number is under 80A, this kit will fit your application. If over 80A, a larger gauge wire would be required or use our Kolossus Flex 4 gauge amp installation kit.

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.

Bassik Twisted Pair 2 Channel RCA Cable

Our Bassik RCA is just that, a straight forward design.

Bassik RCA Features include:

  • Oxygen Free Copper construction
  • Twisted Pair Geometry for noise rejection
  • Ultra Flex, soft touch PVC allows this cable to fit in tight places
  • Easy channel identification
  • Gold Plated RCA Connectors.

About KnuKonceptz KCA Power Wire and how it compares to other cables

  • 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

  • We've compared several popular 4 gauge amp kits from other manufactures. The above chart displays the manufacture and the calculated gauge based on area.
  • All cables tested were labeled as 4 gauge. The X axis indicates gauge by area and where each cable's measurement placed itself on the American Wire Gauge scale.
  • Several brands barely reached the required area of 8 gauge.

Every KnuKonceptz amp installation kit clearly states these critical specs:

  • 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. KnuKoncept does not rate cable based on watts. Amplifier manufactures do not always truthfully state the output of their product, check your on board fuses!

Customers like the quality of the electronic cable. They say it's durable, and the craftsmanship looks great. The copper clad aluminum seems to be a nice viable material for this application.

The remote wire is attached to RCA, and it'll be hard to break.

Great little kit

Great little kit
I'm still eating this kit a 5 cause of the quality of it for the price, only thing is the fuse was installed in the fuse holder and broken at the manufacturer. Just a tiny bit more QC and it'll be perfect ( honestly I was gonna replace the100a fuse with a 60 or 80 since this is only gonna power a 400.1 kicker amp )

5.0 out of 5 stars SUV Owners Please Read. Power Cable Is A Bit Short But Works
Reviewed in the United States on June 11, 2015
Installed this on my 99 Tahoe after reading tons of reviews. This kit is amazing compared to walmart junk and is true to its size. Everything I needed was in the package and the install was easy yet time consuming. The power wire was a bit short for installing on a full size SUV so bare that in mind. It will work but when dealing with SUV's you wont have to much to play with. I routed mine from the battery, through the firewall, behind the front kick panel, down both sets of floor trims (front door, back door) and into the cargo area and barely had enough left over to install it into my amp. This left me with no options as to where I wanted to mount my amp. It is right behind my rear seat. There is no more cable to move it. I would have payed extra if they offered a kit that was made for SUV's that had longer cables. I didnt want to mount it there but I have no choice. All of the other cables were fine running from the head unit. I like the fact that the remote cable is run inside the rca cables. During the install I wasn't having to fidget with getting 2 cables under my door trims. Everything works great and all in all this is the best value cable kit I found for the money. I just wanted to let SUV owners know that you will be limited on your power cable.
Maybe this company could consider making kits with different lengths. I am sure compact car owners have tons of cable left over while I struggled to get mine to the back of an SUV. I hope this review helps someone. Thank you for reading and Happy Shopping!!
