Features

  • 18 Feet 4 Gauge Ultra Flex RED KCA Power Wire
  • 3 Feet 4 Gauge Ultra Flex Black KCA Ground Wire
  • One inline fuse holder with 80A AGU Fuse
  • One 17 Foot Bassik Twisted Pair RCA Cable made from Oxygen Free Copper (OFC)
  • 20 Feet Bassik Black 14 Gauge CCA Speaker Wire

Description

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. 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. Wire gauge is crucial to powering your system correctly. Undersized cable will create unsafe conditions and may shorten your amplifier's life 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 RCA Features include: 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. 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. 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. 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.

    • SUV Owners Please Read. Power Cable Is A Bit Short But Works
Color: Blue
Review Image by Steven Housden
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!! ... show more

    • Not a bad wiring Kit, i dont have much experience.
Color: Blue
I bought this product because of the quality that came with the savings. It had really good reviews (except for a few people who sounded like skeptics) and id like to agree with most people that this seems to be a great product. It came with a lot of extra pieces (grommets, spades, loops, rubber caps, screws, zipties) most of which I did not use, but I can imagine most other people using them. The extras were really helpful. My only gripe about this product was that the ground cable was too short. I understand you want to keep it short for electrical reasons, but i almost ran out of cable to work with. The positive cable, no issue at all. The short ground cable is why i gave it 4 stars. The quality seemed great, and there was nothing broken in my package, so i dont understand how people break their fuses when they seem pretty durable. Also, as a beginner in this realm, i didnt find it difficult to stuff the wires into the fuse or anywhere else. Yes this 4 gauge wire is thicc AND yes it was hard to stuff into some areas (ive been used to that all my life), but if you take your time and gently prepare the cable right.....boom in it goes AND without having to shave any extra wires away. Beat that you complainers. My sub worked fine after using these cables and they seemed of great quality. Definitely worth every penny to me. Id upload pics, but im having phone issues. ... show more

    • Real deal wire, leaps and bounds better than the competition
Color: Blue
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. ... show more

    • I Highly Recommend this Wire Kit for 1000w RMS and Lower!
Color: Blue
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). ... show more

    • KnuKonceptz 4 gauge amp kit
Color: Blue
I purchased this kit mainly based on price and the reviews. I didn't need a kit this large (4 gauge) was overkill, but for the price I was able to get a good kit. There were other brands priced about the same but were not what I consider high quality or high end. I was a bit skeptical about this since I did not hear of the company before. I made the purchase based on the positive reviews. I would give this kit 5 stars due to the quality and price. I think this is a great kit to install for a medium sized system. I do have a few issue with the kit, but these complaints are only based on the fact I did a custom install and this kit did not fit my exact needs. 1. There is no seperate remote wire. The wire is attached to the RCA cable which I did not like. I put a switch on my remote wire so I could turn the amp on and off. When the remote wire is attached to the RCA's an installation like this does not work. 2. The speaker wire was only 18 gauge. If you are going to provide a 4 gauge power wire I think the speaker wire should be at least 12 gauge. 3. The length of the ground wire may not be sufficient. This kit only had 3 feet and I needed 4 feet. The power wire was about 2 feet too short. I would have wanted 20 feet of power wire and 5 feet of ground to make sure the kit was sufficient. All in all this is a great kit for the power wire and RCA's. The connectors are also thick and if you crimp properly will hold well. My complaints are only based on the fact I did a custom install that was a bit unusual. For a normal install and a starter system this is a great kit! ... show more

    • Just installed (updated 7/24/13)
Color: Blue
The price of this kit is what all kits like this should cost. Walmart ones have less wire (and length) and cost more. I am currently happy with this kit with a few exceptions listed in the Cons section of this review. This kit was used in a 1989 Bronco and my biggest problem is that I couldn't ground back to battery with this kit. Pros: 4 Gauge is real 4 Gauge. Its not 10 gauge rapped in insulation made to look like 4. ***RCA cable feels like it was built properly (time will tell) I have both + and - amp power leads laying on top of this cable and no noise. Amp Remote line tied in with RCA lines Battery connecters are solid Fuse holder is constructed very well and is easy to work with. Cons: Ground wire is only 3 feet (I knew the length when I bought the kit but it was 15 feet too short for my install.) Had to spend money else where to get more wire. I feel that the Remote wire is on the thin side. Kit came with missing amp connecter for power speaker wire is on the thin side. Actual wire needs to be a gauge or two bigger. Copper Clad (I miss pure copper wires) 7/24 ***Looks like I got one of those odd ball problem cables. I was able to tweak the RCA connecter to eliminate the ground loop that was causing the alternator whine. ... show more
