Ordered this for a Sebring convertible upgrade (140A stock alternator). Ordered on a Friday and received it on Tuesday - excellent/fast shipping! Product is EXACTLY as described. Although the wire is CCA (perfectly acceptable in this application) it is very nice. Jacketing is very supple and the cable is very flexible. On the fence if this is true 1/0 cable however - compared to some older L/A 2/0 wire the wire itself is the same size (this has zero impact on my positive review - look again at the price :-) ). Supplied accessories (down to the zip ties) were all very nice quality. If I had only thought ahead and ordered the crimping tool!!!

I needed to do a big 3 upgrade on my truck, and I chose this kit over others because of it's price. The quality is great, everything I needed was included in the kit, and it performs very well!

I did my big three with the Belva kit and it improved my voltage massively. I use all Belva wiring and a Belva amp in my system and it sounds amazing. Get one and u will not regret it

This kit comes with everything you need to do the big three upgrade to your vehicle. I had a good bit of wire leftover from doing the upgrade to my 1992 dodge dakota. The CCA wire I great for places where you have to make a lot of bends with the wire. Overall a great kit I would recommend to anyone wanting to do the big 3 upgrade.

More like 2 gauge wire. Everything works well aside from the fact that's its not 1/0 awg. Terminals a little big for wire but not a problem. Broke one terminal (my fault) went to store and bought 2 gauge terminals and they fit perfect.

Comes with plenty of cable and is perfect for the big 3. It doesn't come with a fuse but for the price it's still cheap to get it separate anyway

I got this because my cars headlights would dim when I would use my power windows. After installing (which was easy) I no longer have that issue and my audio speakers even sound better!
