    • Definitely Knukonceptz and solid quality
Color: Blue
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. ... show more

    • Best kit in this price range
Color: Blue
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! ... show more

Shopped around for a decent Oxygen Free Copper kit for my car. Found a few that were $20 cheaper. But seen multiple reviews on how the gauge size was off. Every cable in this kit is freaking quality! About a 90/100 Copper to Shielding ratio on the power cables. Speaker wire is super thick too. All cables are OFC as well! ... show more

Got this to power my Rockford Fosgate 750w amp and it delivers more than enough power to my amp. The whole kit is good quality stuff!!

    • Almost perfect!
Color: Blue
I bought this kit. I was looking for a true 4-gauge kit with OFC copper (in a lot of kits the power wire is aluminum, not as high quality as OFC).... anyway this kit was a good price from Amazon. It's hooked up to a Phoenix gold ZX600ti running dual 10 subs in a sealed box, amp in the trunk, sub on the back seat... all the wires were long enough to do the job with a little to spare and the install went fairly smoothly - although you do need to know what you are doing and not be impatient. I read a couple of detailed free online guides to make sure everything was covered by the instructions and I think this is a good idea as it minimizes the possibility of errors, which can potentially be dangerous. The system is bumping and I'm LOVING the sound of my setup. I'd say the hardest parts of the job are drilling the firewall / installing the grommet (more on that later) and connecting the ground wire. The power wire is chunky and nicely flexible and the crimp-on spade connectors are solid and fit securely. I want to give the kit around 4.5 stars. I would give it 5 stars but for two minor niggles.... one is the "built in turn-on wire", this is built into the RCA cable but is woefully thin wire, I broke the strands when connecting it up and so ended up using one half of a piece of unused speaker cable (I had positioned the map really close to the sub in order to use as short a speaker wire as possible so had a bunch left over). The other minor complaint was the grommet. This is used to protect the power wire at the point where it pokes through the sharp hole in the metal of the firewall, otherwise after time the insulation can get worn away by vibration and cause a short. The supplied grommets (there were 2) were woefully thin and weedy and I broke both of them just trying to push them into position. A grommet is not a difficult component to source and you could probably pick one up for a small amount. It's an important piece though. ... show more
