Definitely Knukonceptz and solid quality
I ordered this kit as well as a few other items for my LoC, amp, and sub installation for my 11th gen Civic. The 4G cable is far better than I had hoped it would be, very flexible, and it is OFC (Its been tinned so it won't look like copper). For anyone who isn't sure or doesn't know wiring, ground and positive cables are pretty much the same, just good practice to use different colors of the same gauge. Good practice would be to go actually research what it is you need thoroughly.This kit is solid for a 4G power/ground setup for my amp, although I'm using a distro block before it goes to my AMP itself. The length of the positive is more than enough, I was able to cut enough for the ANL fuse block near my battery, as well as a good length to go from my distribution block all the way to my amp. There's less of the black version which is meant to be used for ground, where I'm having to install my distribution block vs my amp, I had just enough cable, but for anyone not grounding directly or installing next to the amp I would recommend purchasing more black in a longer length.The 12G included for speaker I'm using for my sub, the cladding on it is great, its very flexible, and I'm really happy with it. 3rd party ferrules fit just fine so no issues there either.The ANL fuse holder is solid, what you would expect from a smaller fuse holder, I just wish car manufacturers would make it easier to install aftermarket components like this. Pretty easy to install, just had to finagle the gasket around the ferrule and heat shrink before installing it to the fuse block, but otherwise its holding great.I won't be using the RCA cables included by they look really solid, flexible like the rest of the cable, and definitely quality. I will however be using the remote signal wire they included, the jacket on it is thicker than standard 18g, and I might as well. The included terminals and heat shrink is pretty standard and works well, no complains there either.I do not recommend anyone to install their own electrical equipment if they aren't able to pick up information and understand wiring basics. I also don't recommend relying entirely on this review to determine if this is the right kit for your car. Know how much wire you need before you order, coming up short is more costly, and its best to know what you're doing and what you need in advance. Otherwise, I definitely recommend this product.

Best kit in this price range
Best quality kit for the money.This is Pure Oygen free cable, The wire is top quality solid copper and has a tin coating (tinned). DO NOT confuse this wire with a CCA (Copper Clad Aluminum) wire. Pure copper wire conducts about 60% more than CCA wire. A decent CCA wire would have to be 3 guages bigger than a pure copper wire to perform the same. So basically this wire will perform about as well as a 00 guage(-1/0) kit made of CCA.The wire is SUPER soft and flexible, feels almost like a big rope of blue candy. its not rigid AT ALL, if you have to snake this through a car body, be prepared to use a wire hanger because it will just bend like crazy. The remote cable is great quality. The RCA's are very good quality & very low noise. The speaker wire is also top notch. I have a 350z and there is more than enough wire left over that im thinking of upgrading the "Big 3" with it. Although the wire is not 0 guage, it is of such high quality that i believe it will suit me (2500 watt @ 2ohm rms system) just fine. The flexibility of this wire is such that i was able to make my battery to capacitor cable only about 7'. I am running a 2000 watt rms amp to a dvc 10" with the supplied 120 amp fuse. Could'nt be happier =)P.S.I see pepople saying that sometimes this wire wont fit into their amps because its to big. This is why they give you TERMINALS! You never have to shove the entire wire into the amp or battery, That looks like total crap anyway... crimp on the supplied terminals for a quality install!

outstanding mains
I run a Rockford power bd 1000 with this kit, I didn't need the remote wire that is built into the rc cables. I did use the cables because mine where way to long, they work fine but the cables and remote wire are of cheap quality, i like the fuse block, really wish it had a few more 4 gauge butt connectors. But the reason i paid for this kit was really the power and ground wires, and add i expected they did not disappoint. This oxygen free copper wire is true four gauge and is the nicest wire I've ever used, very sturdy but extremely flexible with nice soft manageable feel. Handles the heat from my high performance engine with ease, i did like the black and red wire ends it came with for speaker wire and the main wires also, nice touch. It's a well put together kit ,all of its pieces work satisfactorily, but the star of the show the main wires really brings its a game, and i would have paid that price for them wires only, everything else is just Pro bono to me. If you have any complaints because you didn't like something about the window dressing it comes with i would suggest trying to find an equal quality set of true gauge power and ground (same length) alone for less money. I recommend to anyone who wants top quality wire powering there amp. The equipment you run isn't cheap, don't go cheap supplying it with power.

Fit Kia Niro 12v Battery Perfectly.
I think these are the best, highest quality amp install cables you can get for the money. The flexible insulation makes routing them a breeze, the conductors are thick and high quality oxygen free copper. I only wish they offered multiple sets with options for longer or shorter ground and power leads. The terminals fit perfectly on my 24 Kia Niro 12v battery. Make sure you install the fuse properly and you’re golden.
