Greater than one weekAfter painfully running the RCA cables from my head unit to the trunk of my car and hooking up the amp, the audio kept cutting out. Come to find out its from the poor contact on the RCA cables to the amp. They fit very loosely and unfortunately thats the worst cable out of the kit to have to replace. Well I crimped down on the ends with some pliers for a tighter fit and so far its been OK but thats not a good sign for longevity on a brand new cable. I expected better.

> 3 daySave your $$ CABLE is half copper ..falls apart when you strip it..all crimp on ends are thin and cheap..I went to auto parts store and bought real ends and #4 wire. Not much more to do it right. Boat wiring should be top grade. I will try to return

> 3 daySuperb quality, incredible, the wires flex and bend every which way, I have a civic coupe and the wires were just big enough for my car so if you have a sedan and you plan to install in the trunk I would suggest that you buy a few extra feet. Search for this KnuKonceptz KCA Kable 4 Gauge Power Wire Blue The RCA cable comes bonded with a third wire maybe a remote wire? Any way this is a fantastic deal high quality and I was very happy with it.

> 3 dayDont mess around with a cheap wiring kit. Never go cheap on something like this. This kit exceeds my expectations. Comes with absolutely everything you will need to install, including the little zip ties! Would buy again, wish I wouldve just bought this one in the first place rather than a cheaper one on Amazon...

> 3 dayI bought this last week and installed it into my car this past weekend. Im happy with the quality of the power wire. It pretty flexible and the outer rubber seems solid, yet soft to the touch. One thing to note that isnt readily visible on the RCA, but it has the remote lead wire embedded into it so you wont need an additional remote lead wire. The RCA connectors feel really cheap to me, but the power cable and the connectors and fuse holder are good. It even cam with a nice grommet for the firewall. Happy with the purchase, I just wish the RCA was a little nicer.

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)
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
- American Wire Gauge
- Max Load (amps)
