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.
- 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!
Bassik Twisted Pair 2 Channel RCA Cable
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.
- 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 if they met the minimum area requirement for 4 gauge.
- All cables tested were labeled as 4 gauge. Area was determined by measuring the diameter of the strand and then calculating the strand count.
- Several popular brands failed to meet AWG standards (21.1mm2). Others used excessively high fuse ratings on inadequately sized cable.
- NEW Mini-ANL Fuse Holder
Our water resistant fuse holder now holds a more durable Mini-ANL type fuse. This form factor uses a stamped element that is unfazed by bumps and vibration.
- Properly rated for each application
Buying the proper gauge wire is critical for your amps longevity. Making sure that kit includes the correct rated fuse is critical to your safety. Too large of a fuse puts your car at risk to hazards if an accident occurs.
- Unsafe fuse ratings
Fusing too high not only is unsafe in an accident. Oversized fuses on smaller wire creates a hazard of its own. Review the manufacture's included fuse size.

This product is awesome. There's not much one can say about wire, but I'll try. First of all, the jacket on this is pretty darn tough for being so thin (So don't look at the pictures and think "I don't want that! It'll melt or crack or something! It wont..) Second, it's super flexible, I had no issues installing it in my 2002 Maxima, Which there is very little room under the door entry trim. Lastly and most importantly, it's true 4 gauge wire so you will get the exact amount of current you will need for your amplifier (if your amp suggests something close to 4 gauge) Also, as you would assume, there is a substantial length of wire, I did my car clear to the trunk and had a good 4 feet to spare. As for the other components of this kit- I found them to be great as well. The terminals were the exact size as the wire so no trimming was needed. The terminals were also very easy to crimp. The fuse holder is solidly built with o-rings inside to lock out moisture and acidic gas that flows from your battery (You cant see it, but it's there, and it can ruin fuses in cheap fuse holders) You get loads of speaker wire, I only needed about two foot for my install and that didn't even make a dent in the roll. The RCA's were nice. They seemed tough and the built in remote wire was a nice touch. However, the right channel connector on one end of the wire was very loosely fitting. Probably just a fluke, as all KnuKonceptz products I've seen were fantastic. I just bent it ever so slightly to get a better connection, worked fine. So I'm not one of those guys that heard about this stuff from some famous youtuber and then went out acting like a sales rep for it when they have no prior experiences with wire installation, This is an honest review from some one with knowledge. I believe this product deserves the full five stars. Well done KnuKonceptz, Well done.

This wiring kit is honestly really really nice, I'm running a Sundown X-8 on 1000w RMS with a SoundStream P1.1000D. The wire handle's this just fine! Also, all the included bits and pieces are nice to have, honestly there is almost too much extra's like terminal connectors and stuff, but that isn't by any means a bad thing. The remote wire that's in-between the RCA connectors is really convenient and easy to hide, it's also harder to break since it's connected to the other wires, whereas most remote wires are individual and can split easy since they're so small. The fuse is nice as well, it's 80 amps (I believe that's stated in the specs but wanted to add that just in case). I only have 2 complaints, and they're small ones specific to my scenario. First, the speaker wire is too thin for my setup, it's 14 gauge which will NOT handle 1000w RMS obviously haha (I went with 8 gauge for my setup just to be safe, 10 would have been fine). 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. Again, those are both specific to me, I don't expect most people buying this kit to be pushing the amount of wattage and amps that I am through this wire, so 14 gauge would be fine, and in most cars (I'm driving a Volvo 240 Wagon) the 3 foot wire is totally fine.Overall I am really happy with this wire and I think you will be too if you get it, I just don't recommend pumping anything more than a 1000w RMS through it was that would be too much and might blow the fuse (1000w RMS equates to close to 80 amps at this length, of course that's just an estimate and the amperage changes with wire length and what not).

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!!

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!!!

I'm no expert on audio cables. I just wanted to add some bass (I'm planning on maybe 200watts). I haven't finished the project yet but I ran the cables from the battery and the central console where the stock radio is (I removed it to replace it by an aftermarket one) and wow I'm impressed by that kit. It's got everything you need, from tie-wraps to crimps, from that big fat 18' 4 gauge positive cable to the little remote one. It's all of the perfect lengths (and then some). The fuse I received is rated 100amps (which is 20 more than stated). Again, I didn't try anything yet but I mean, the main cable is so thick I guess the whole kit is worth it only for that. Oh and by the way, as other stated, good luck crimping that fat cable! I used my bench's vise and I can tell you it's not going anywhere ;)

I have used several manufacturers for items similar to this in the past, and this is up there, quality wise, with the kits that are three times the money. Solid cables, good quality terminals and the system works perfectly now installed. Would buy again 100%.

Was looking for a kit that didn't cost me an arm and a leg, this one fit the bill extremely well.Came packaged in clear plastic case, had pretty much just the cables and accessories and one cardboard piece with install instructions.The cables are nice and thick, much more so than the other competing brands at this price. Gives me some reassurance that it will be able to give my amp the current it needs when it's pulling 500+ watts. The finish and quality feels very good, not messy and has a decent amount of accessories to make sure you have everything you need to wire up your sound system.Overall very happy with the product and how well it performs.
