pretty good

I have just installed this in my blazer and it helped out alot. The only thing I didnt like about it, is that you have to cram the 0 gauge wire in the battery terminals and it gets a little messy. But other than that it was a great buy. I would recomend it.

worked great

I just upgraded all the cables for my "big three upgrade" using this kit. I put it in an 07 toyota and it tremendously helped my 1200 watt RMS speaker and sub system. Thanks Sonix!

Good wires, good price

I should have bought this with my system as its far more expensive buying 0 gauge here in Australia, this is great stuff at a great price. Only reason im not getting it now is because USPS takes over 3 weeks and I am willing to pay more to get my system running sooner but if your looking at buying sub(s) and an amp that require over 1000rms definately think about getting this with it.

Pretty good.

The ring terminals for the 1/0 AWG are too small even with taking out the spacers that are on the inside of them. The ring terminals also have very cheap screw heads that will round off or start to strip because its a non hardened metal. Same goes for the battery terminals, you can not get the wires inserted perfectly without cramming them in and then it leaves it looking messy. The wire and cutters are good quality and it is a fair price. The cutters are very sharp which made cutting the wires extremely easy!

Not bad, could use improvements.

The ring terminals and the battery terminals were both too small to fit true 1/0 AWG wire into them. With the ring terminals I even took out the inside spacers and it still barely fit. The ring terminals are low quality because the screws to secure the wire inside of them are just too cheap of a metal because it's not hard enough metal to take the torque. I ended up stripping the head of them. I really liked the wire cutters, they were sharp and cut cleanly through the wire with no problem.

It works!

Real true to awg standards, 100% ofc wire. Its legit, and does help with my voltage drops. The best thing has to be the terminals though, they are sick. Any gauge, multiple batterys, multiple amps, anything they can be used for.
