Good
This wire is very flexible and fit nicely in my 2000 nissan maxima. ring terminals were a little fussy, but that was operator error. very nice 150 amp fuse. Lots of wire crammed into it. Very inexpensive for the quality. I would recommend this to anyone looking for an upgrade.

Decent Amp Kit
I am a professional installer first of and my father is an electrician. Following the AWG- American Wire Gauge standards this is not 1/0 wire it's closer to 2AWG, please understand that true 1/0AWG copper wire will cost around $5-8 a foot.
That being said for the price it is an amazing kit but should be marketed as 2AWG.
When compare to Kicker and Memphis true to spec 1/0AWG wire there is a major difference in size and weigh over all. 5 feet of Memphis 1/0 Wire weigh the same as 17 feet of Belva 1/0AWG.

Great Wire
It's the size it says it is, and powers my 1400 watt system with no problems. For the price and ease of install, I couldn't be happier!

Great deal
I got this kit because I got a deal on it with my amp...great starting kit...didn't have any problem with it when I installed it...The ground cable was to short for me but that is due to my custom box..All in all good 1/0 Guage kit

good product
Good product, they give you plenty of length. Only complaint is that the o connectors are really hard to clamp down and the rcas are kinda cheesey but work

Huge
I have never ran 0 gauge before and when I got it and took it out I was surprised but the big wire didn't really hurt the install it is still hidden under the carpet and it's thick and flexible so it was easy to run through the firewall. Now I'm gonna get the Belva big 3

True 0 AWG!
Pros:
This kit comes with everything you need for a 0 AWG amp install with RCA inputs.
Cons:
NONE
I would definitely recommend purchasing this kit if you need a quality 0 AWG kit at a fair price with super fast shipping!
