Good for the price, but obviously not the best

Definitely worth it for the price, I got them with a kit though, but for the cost I would recommend this as a starter or weaker kit. The power wires aren't 4 gauge at all but they're enough to power maybe like 500 or 600 watt amps and sound fine. They're a bit not flexible but they all still bend and get what you need done. For a higher powered system I would recommend Stinger or Kicker but these work fine, just at lower volumes. They are shielded so don't let other reviews turn you away, I had to attack them with knives to cut some of them and the RCAs got pretty badly sliced by my car but are still under whatever material you want to call that.

Good buy for the price.

great for a low end kicker or rockford set up,

Good for your everyday bass enthusiast, the kicker and rockford people, not for big bass applications.

You get a great deal

I know to expect no more than you pay for, and I got a little more on this one. My complaints are that the power and ground are more like 6ga than 4. Other than that, everything everyone else said. I'd buy again.

Gets it done!

Literally DOES have everything you need. The ground cable is very short, however that is my only problem with the kit.

Not the worst, but not the best either

Bought this kit for wiring up my two Rockford Fosgates and Kenwood monoblock amp. Entire kit was okay for the most part, but after finally seeing it all up close, I immediately wish I had spent the extra money for a better kit. The power and ground cables aren't true 4-gauge wire. The "copper coated aluminum" just does not cut it for me. The strands fell apart when trying to crimp a connector to the end, twisting them together, or inserting them into the amp terminal for power. Might be good for a starter kit, but definitely not for those who have been in the car audio game for a good while.

I do not recommend this amp kit

I am currently running a Kenwood KAC-9105D with this amp kit and it does work but I wish that I would have bought a better kit from stinger. The wires are kinda cheap and appear to be aluminium coated with copper. This kit would be fine for 500 watt amps or less in my opinion

Great Kit

This is a great wiring kit. For the price, it simply can't be beat. I highly recommend it to everyone, not just those who are on a tight budget. I mean, do we really need name-brand wires? These do the job perfectly fine! I've been using mine for over 2 years now and I have no complaints.

First Time

This was a great value and I like the color of the power cable.Just like the light on the Kenwood amp.

Ehhh It works...

If your gonna sell a kit product make sure everything fits together properly. The power wire doesn't fit very well in the fuse cap and the cap misthreads constanly. I prefer the block type fuses but it was a cheap kit and it does what is supposed to do overall. Metal quality is good, the insulation is excellent, but the terminals and fuse container suck. Didn't use any of the terminals, had to custom make terminals but not the fault of the kit, this vehicle had some wonky connections.
