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 are mixed about the fit of the electronic cable. Some mention that the length was perfect, the wires are amazing and much larger than competing brands, the power wire is plenty big to fit the 4 gauge, and the fuse holder is not too big. Others say that the ground wire is a bit short, the turn on wire is small, and that the fuse for the wire is too small.

"...Second, the ground wire is a bit short, if they included a 5 foot ground this would be the perfect kit, but still it was long enough for my needs...." Read more

"...The terminals were the exact size as the wire so no trimming was needed. The terminals were also very easy to crimp...." Read more

"...All of the wires are amazing and much larger than competing brands...." Read more

107 customers mention74 positive33 negative

Customers are mixed about the thickness of the electronic cable. Some mention that the wire is thick, with nice thick strands. The connectors are also thick, and if you crimp properly will hold well. However, some customers complain that the actual wire is thinner than expected.

"...The connectors are also thick and if you crimp properly will hold well...." Read more

"...But this is truly quality wire. Its flexible, not stiff, yet its thick.Looking for an amp kit....STOP HERE!" Read more

"...First, the speaker wire is too thin for my setup, it's 14 gauge which will NOT handle 1000w RMS obviously haha..." Read more

"...When it says 4-gauge...it IS. I was very impressed by the thickness of the battery cables. Good quality cables/wires...." Read more

102 customers mention15 positive87 negative

Customers are dissatisfied with the fuse. They say that the fuse itself was bad, the fuse inside the holder was broken, and the amp fuse could also be better. Some customers also mention that the power wire burning up and that the crimp made strands break off.

"...of the quality of it for the price, only thing is the fuse was installed in the fuse holder and broken at the manufacturer...." Read more

"...The really irritating thing was the fuse was dead to start with...." Read more

"the fuse inside the holder was broken had to buy another one" Read more

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 )
