easy to use, works well.
i'm no car audio installer but am happy with this product. all parts present in the pack needed to wire in an amp and sub, got mine wired into a navara no issue, cable is good and flexible, all the parts are easy to work with and yeah, it just does what it's supposed to, can't ask for a great deal more that that.

Quality at its best!!!
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!!!

100% Amazing
So Guys and Girls, If you are like me and want sq or spl in your car this kit is a really good place to start, Amps need power to work properly, to get power your amp you need to be able to supply it. I recommend this kits 100%, the cable is easy to work with and very flexible for those hard to reach areas and delivers the power to

Decent value kit, the power cable is particuarly solid ...
Decent value kit, the power cable is particuarly solid! For those worried it doesnt contain signal wire to turn the amp on and off, it actually has this hidden between the left and right RCA cables

Very happy with this!
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%.

Great kit. Real good quality power and ground cables
Great kit. Real good quality power and ground cables. RCA was a little let down and no separate remote wire but for the price it's a fantastic buy. Will be buying again

Real deal wire, leaps and bounds better than the competition
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.

Quality, Quantity, Price. 5/5 would buy again!
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 ;)
