Power / Ground Cable Specifications

Wire / Cable Type
Wires and cables are made for different uses. This use that the wire or cable is made for.

Please make sure that the wire you are purchasing matches the intended use.

Power / Ground Cable
Wire Gauge
The measurement of the diameter of wire. As the gauge number increases the size of the wire decreases. As the wire gauge number decreases, the diameter of the wire increases. For example, an 8 gauge wire is going to be larger than a 16 gauge wire.

When purchasing wire, make sure that you know what size, or gauge of wire is needed.

1/0 gauge
Wire Material
The material that the wire is made of. Copper & aluminum are the most commonly used materials. OFC - Oxygen Free Copper is the ideal choice for wire material. Copper is a superior electrical conductor, & does not expand or contract with heat. CCA - Copper-Clad Aluminum is a suitable choice for lower powered or budget applications. The power transfer is not on par with OFC, but this material offers significant savings.
CCA (Copper-Clad Aluminum)

big 3 upgrade kit

March 11, 2014

This is an perfect kit to do the big 3 upgrade. It actually contained enough wire for me to have sufficient wire up everything up front and to complete the ground and distribution block wiring for my second battery in the trunk. Would highly recommend.

Great KIT!Best BANG for your BUCK!

February 17, 2014

At first I was a little skeptical about the kit but once I got it turned out to be great. I installed it on a 02 cavalier and it fit perfectly, and for $50 for 0 gauge what else do you want.

Im currently running 3 amps in my car and this was definitely a great upgrade. Would defiantly recommend to anyone that's on a budget and wanting to do a BIG 3 upgrade.

Instant Sound Quality Improvement

May 16, 2014

I installed this in a 1998 Grand Prix GTP, the entire install took about half an hour. This was well worth $50!! Before this, I was having problems with headlight dimming when the bass would hit, the entire car would sometimes shut off, and the windows were getting slow. After I installed this, the engine seems to crank over (start) faster, no more of the entire car shutting off, windows seem to work faster, and best of all-- a significant improvement in sound quality. I also had a lot of alternator whine prior to this installation; this kit seemed to greatly reduce that (it's still there, just not nearly as noticeable). One should take note, that this product DOES NOT come with the extra ring terminals as shown in the picture.

July 28, 2014

I have to say I was impressed with the wiring kit. It came with everything you need including instructions! This made installing the kit real easy, no guess work. The wires are the wires are 10% OFC and XS Power makes sure it makes up for not being 100% OFC by adding more strands. This is a great product and I highly recommend this to anyone who demands mass power distribution.

Big Upgrade well needed

October 26, 2014

Bought this from there Ebay store and received it within two days. I installed this before I installed my bass amp and what a difference in my voltage. My voltage with my truck running before would stay at 13.3 to 13.9 with bass notes now with this kit voltage stays at 14.8 to 14.9 voltage never drops with bass notes. Use this kit with an alternator upgrade and/or battery upgrade ( I did both with 250AMP Alternator with two XS D3400 batteries). even my truck runs stronger with this upgrade.

Must have for Big Installs

March 13, 2015

The Big3XP kit has all the necessities if you're thinking about adding some serious power to your ride. There's more than enough 1/0 cable to get around under your hood and the accessories pack isn't too shabby either. My only request is that they up the number of extra 1/0 "lugs" to 4 or 6. The pack only comes with two and if you need the Big 3 for your system 3 pre-cut lengths of cable with lugs already attached and 2 extra lugs for your custom install doesn't quite get it done so do yourself a fav and add another pair of lugs if you order this kit.

Big 3 means Big XS Power

March 4, 2015

Pros:

-All wires 1/0 gauge.
-Instruction were in there for placement of grounds
-2 Extra 1/0 Gauge Non insulated Right terminals
-Extra Shrink Wrap and Cable Management Mounts
-Price

Cons:

-CCA Wiring
-Wires were a bit long (See conclusion)

Conclusion:

The XS Power BIG3XP was a great addition to my car and any car. Since I run only 2000 rms I believe having CCA was a good choice since its only to supply power to the car batt and grounds. The wires was a bit long for my small subaru impreza but for any big SUV or Engine bay with alternator on the opposite side of the battery will be a good use. (This is a good thing) Because I did the big 4 upgrade the same time i changed to a HO Alternator and New Batt, I didn't see the affects of the dimming of lights or the drops in voltages. Over all this was definitely a great buy and a definite upgrade for those people who do not want to get their hands dirty crimp lugs and ring terminals together.

Side Note:

I took off the Shrink wrap to see the connection and the crimp was factory crimped but not soldered. I soldered all connection to get a better connection from them.

I installed these cables on a 2009 Chevy Silverado that the lights would dim when the base hit with the radio up to mid range...was told this would take care of the problem. No change really...my voltage will show more when I first start the truck but after 2 or 3 minutes it's back to where it started with the problem.

For the little bit of money this cost, it's a very good upgrade. I haven't actually used a volt meter to compare before and after, but my stereo definitely got louder and no dimming lights. The increased efficiency in transfer route keep the voltage constantly stable equaling higher voltage for the amps to use.

great product included everything for my upgrade with a lot of wire to spare. this was installed in a 2004 chevrolet tahoe. I was able to do battery positive to alternator positive. battery ground to alternator ground. alternator ground to chassis and alternator positive to the little junction box. after all that I had about 3.5 -4 feet of wire left over. only thing I could find wrong was that one of the terminals was a little loose but nothing a little extra pressure can fix.

November 13, 2015

Have not installed it yet, but seems of good quality. Connections are nice, cable and jacket feels good and solid.

In case you don't know (like I didn't) this needs to be fused between the positive alt and positive battery terminal. Fuse size is what your alternator puts out. Mine is a factory 180 amps so my fuse is 200.

October 19, 2015

I thought I had selected the 100% OFC when I originally added this to my cart but I was mistaken; this is the Copper Clad Aluminum model. Next time, I'll read my screen a little more carefully. Having said that, the construction quality of this kit is top notch and the cables do work. They are still WAY better than your stock 10 gauge alternator/battery cables, I assure you. If you are running a high amperage system, however, you'll definitely want to stick with the 100% OFC cable. Thankfully, Sonic has a link on the product page to the 100% version so I hope you will learn from my mistake!

Recommend this if you are upgrading electrical. Easy to work with despite size of cable. Be familiar with your vehicle to ensure wire does not come in contact with moving parts or extremely hot objects. I would suggest having the proper crimpers/cutters as well or solder and a torch.

August 26, 2016

I have a 240 amp mechman alternator, so I definetly needed a big 3 wiring kit. This kit is great. I didn't realize while I was installing everything that I had ran the alternator power wire across the intake manifold on my car. About a month later I popped the hood once more to replace my serpentine belt and saw that the wire had been sitting there on this hot manifold the whole time. I looked at the wire and not a single burn mark at all. Not even and color difference. 30 days of sitting on a hot intake manifold while driving to and from work and so on, and this wire was perfectly fine. Very impressed! Not to mention the fuse is pretty big which is also a plus if you're running a beefy system. Definitely would buy again if needed.

Side note. I wish we could upload photos with these reviews so people can see these products in a personal environment. Maybe side by side comparisons with other products.

THE BIG THREE REALLY WORKS NI JOKE

February 5, 2016

The big three is awesome. The hook up was flawless and the product really works. I did have my doubts but the finish results was astonishing. Once I hooked it all up the voltage s :) it straight up and at 14.5 volts. I run high powered cb amps in my vehicles. That big three really works.

Do the wire end come already crimped and ready to install on this kit?
Jason "GSXR King" Waggoner on Dec 30, 2014
Best Answer: Note: there is plenty of wire to cut to your length. Then you must crimp and then heatshrink or tape the ends. I highly recommend and suggest that after crimping the terminals onto the wire, that you use heatshrink on the terminal and THEN electric tapr around for the best and tightest crimp. Careful not to crimp through the wire when applying the force needed to crimp the large terminals!

After installing the XS Power Big 3 kit. I'm losing one volt between the alternator and battery. My 140 amp alternator is steady at 14.4 at the terminal, at the other end of the zero gauge cable I'm getting 13.4-13.6. I don't know why I'm losing a volt here. Could the cable be too long or am I just dealing with a bad cable? Thanks
Peter on Oct 22, 2015
Best Answer: It could be that the power wire is not oxygen free, making it CCA. It's basically a cheaper and less efficient wire compared to oxygen free. Possibly upgrading to a better wire could increase your voltage. The length of the wire would most likely not be an issue since it is only a few feet.

What makes this kit only stable at 250 amps, and what would I have to change to make it able to handle at least 300 amps?
PSYk1ll4h on Oct 24, 2015
Best Answer: I believe it's just a power rating they use to set a safety point. I did the upgrade on my Yukon and I'm running a 350 amp alternator and I haven't had any problems whatsoever.

Best Answer: Hello,

XP series batteries are NOT intended to go under the hood, next to an engine within a vehicle - this is what the D series is for. Furthermore, whether the batter can "replace" your existing battery must be determined by you, simply by measuring your current battery. Lastly, two XP950 , in the right situation, would be a great addition for an extensive audio build.

I have a 3900 watts system not ''rms'' the 2 amps are from Audiopipe..a APCL-1800.D and a APCL-2004..what kind of Big Three you suggest for this kind of system that has a stock alternator ''110 amp'' should i go with the CCA or OFC wires?
A shopper on Jun 4, 2015
Best Answer: Hello,

At best, your system is providing 2400 watts RMS - that is assuming the Monoblock is running at 1ohm and the 4-Channel is running at 2ohms, which is pretty doubtful. Even still, at the lowest impedance (4ohm + 4ohm) your system is getting pretty close to 1200 watts RMS which puts you at the cusp of considering OFC .
