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!!!
Great Upgrade Kit!
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!
Not true 1/0 awg
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.
a++ fast shipping
Great product works well and fast shipping. Would buy again.
Belva big 3= awesome
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.
good thick wire but still flexible come with lugs and heat shrink for a clean install
Quality wire and some goodies for mounting it wherever. Good upgrade over your old battery cables
Great quality wires. Exactly what they said it was. Thanks
1000 to 1500.
1000 /1500. And you good with this one. To bad it not true 0. For the price you can't beat it.
Great price for your 'big three' upgrade. Wires are easy to work with too.
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
GREAT PRODUCT FROM A GREAT SUPPLIER
Bought this as I needed to do the upgrade, at the same time I was upgrading my power and grounds for my amps to 0 gauge and I wanted all my wires to match. SE You guys ROCK!!!
It worked out perfect! Geat value great product badass bro
great product , great price. Not true 0 gauge but for my application it's just fine. Speakers are so much louder and power is much greater.
Not that bad But!
THE RING TERMINALS ARE LOW QUALITY BUT OTHER THAN THAT IT'S OVER 4 STARS
Comes with everything needed to improve the electrical system on your car. A must have for older cars being fitted with high wattage audio systems and such.
Seems to be very good quality for the price! Has been a great upgrade along with my 200amp alternator.
More than I expected
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!
This is a good quality thick cable, others say Its small, its very big. If its not 1/0 guage, then its very close to it. It is double the size of my 4 guage power cable.
I don't think the wire is true zero but it fixed my dimming lights and my voltage stays steady now. Overall pretty happy and would buy again
If you are new to Sonic, they are the best in pricing and shipping fast. I finally got to install which was rather easy, after watching Sonic's great video on how to do it... LOL. I loved the flexibility of the wire which made it easy to route it to all points. There was enough wire left that I decided to buy more terminals and do the "Big 4"(alternator ground). It has helped a great deal maintaining voltage and the lights dim less than before. I will consider a Farad capacitor to help more.
After dealing with Sonic for 14 years, I can't imagine going anywhere else! Thanks guys!
This product is greatly recommended to use when having a system in ur car! The upgraded thicker wires made a difference in the sound. the wires also helped out with the dimming of the headlight when u really cranking up the sound but I didn’t like the fact the kit didn’t come with an in-line fuse.
In my opinion this kit is a must have with any size audio system! Fairly easy to install depending on the vehicle. It is a great added protection and upgrade!
Just bought this kit , and it works great comes with everything you need rite down to the wire ties .
Quality Product! Great Price.. Included terminals made installation a breeze!!
Just the upgrade I needed
Very easy to work with
Great budget price
Cons none that I can think of I've used belva product before and never had a problem so far
Everything you need
Everything you need to do a big 3 comes in this kit. Wire is very flexible. Comes with 3 ends already crimped.
Nice kit for the price every thing I needed to have to install to my durango.
I love it. Couldnt be more happy. Delivers the power i need
Great product and is easy to install and has a great price
Cables are well insulated! Fast shipping too! Very happy with this big 3 setup in my 1987 Monte Carlo SS
Not bad for the price...This is a budget minded kit!!
Absolutely great value and product
I would highly recommend this to anyone that needs to do the Big 3 or 4. There’s plenty of wire and it looks to be great quality of cca wire. It’s thick and flexible best of all it gets the job done
wonderful value, highly flexible power cable.
when the lights were dimming when the bass hit and capacitor was struggling to keep charged, I decided it was high time to do the Big 3. This kit offers Value and performance. supple highly flexible power wire was relatively easy to snake though the factory provided labyrinthic pathway.
Kit came with nearly enough power cable to do two vehicles. excellent value.
Don't really need the capacitor anymore, but it has digital volt readout, and gives me a bit of peace of mind knowing should a Xtrrra hefty bassline drop and sustain, there's power-a- plenty to keep my amplifiers happily running in top form, all thanks to Sonic Electronix carrying the Big 3 kit from Belva.
