i used this to install my amp and was happy with the kit it had everthing i needed

This is a very nice setup.. Cea compliant meaning it is what it says it is.
Wire is a little stiff but after soldering the ring terminal to one end it loosened up. Basically this is a very nice kit for any begnner to advanced installers. I wish they had more colors though, that would be the ony con for me.

This wire is great quality, true 4G and 100% OFC !!! I would recommend this kit if you want to get good quality wire with out the Kicker or JL Audio price.

I used this kit to upgrade my current no name brand 8 gauge power and ground wire. It made my system noticably louder. My windshield is flexing now!! It was also very flexible and easy to install with the ring terminals already crimped on. The ground wire could have been just a little longer for my application but the shorter the ground the better so I guess thats not really a problem. I cant say how well the rca cables work because I just reused my current rca's since they work fine. The Rca's included in this kit look very nice and I cant see that there would be a problem with them. I think this is the best 4 gauge kit you can get for the money.

The gauge appears to be accurate. I like the fact that many audio shops actually use this power and ground wire as their bulk supply. The price is right. RCA's are good enough for my needs and don't look like they'll end up falling apart. Very flexible wire.

I just got these today in the mail, and my woofers are coming in 2 days. So i'm waiting for my woofers before I can test the wire, but the gauges are true gauge.. meaning the gauge doesn't include the diameter of the outside casing of the wire. So they're FAT wires, VERY nice, and pure copper.
Very flexible and durable. Probably the best you can get at this price!
Great kit, the interconnect (RCA) cables seem thin themselves... but that's one of the features, the package claims they reduce noise and interference and provide superb sound quality, so i'll be testing them out in 2 days when I get my woofers. But the RCA cables seem to be good quality (other than being really thin), but if they work as claimed, this kit is PERFECT! If not... then i'd recommend buying other RCA cables. But everything else is absolutely incredible! I LOVE IT! Everything is great quality.
