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

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.

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.

This is a very good product for the price, it works perfectly fine although i ended up changing the fuse holder because water kept getting into it. And the power cable was barely long enough. I used it in a Ford Sport Track.

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.

Pros
Great for starter systems
Everything you need to get started
Very flexible
Cons
Not 4awg, is actually 6awg
Not copper its cca (copper coated aluminum)

Well, I shoulda read more of the reviews...The power cable is definately not 4 AWG. Maybe in some other country, might pass for a 6 gauge or so here in the USA. Very fine strands of copper wire. Ever heard the old addage "ya get what ya pay for" never more true. The RCA cables are twisted, but no shielded. This will work for a starter setup with lower wattages.

This is a nice wiring kit. The wire is not true 4 gauge it's more like 6 but it's good enough to push about 600 or 700 watts RMS or just to hook up a 4 channel amp. The RCA's feel kinda cheap but there realiable and get the job done. Overall it is a good amp kit if your not building a crazy system I'd say 600 rms or less. I'd most likely buy this again but if you want a really nice true 4 gauge kit I'd buy Kicker or Tsunami or Stinger.

This is a very good kit for the price. The RCAs are stranded, the wire sheaths are flexible, Quality is good, but the power and ground wires are a little thin. When I contacted customer service I was told that no mistake was made, "you get $29 worth of copper wire, if you want thicker wires, you need to spend $50." Keep that in mind with your install.
