If your aftermarket audio system is putting a strain on the rest of your car's electronics, you might want to upgrade your factory wiring. Rated to 250 amps, this "Big Three" grounding kit will boost your electrical system's performance.
XS Power's Big3XP kit includes heavy-duty 1/0-gauge copper-clad aluminum cables that replace (or augment) your vehicle's battery ground-to-chassis wire, the chassis-to-engine block wire, and the wire connecting the alternator's positive output to the battery's positive terminal.
Another bonus is that the 8.5 mm ring terminals are already crimped to the wires, so you won't have to replace the stock grounds unless you want to improve them or double up. Extra ring connectors are included, so you'll be able to trim the wires to length and replace the terminals if needed.
This Big3XP kit includes:
Warranty: 1 year

Everything you need in a big 3 kit. Cables have plenty of length. The extra terminals are nice since I had to shorten two wires.
Pros: Very flexible cables. Easy to install and route within the engine compartment.
Easy to install and comes with everything you need! Would recommend!!
Great product, all the ends came crimped. More than enough length to run wherever you need. A couple extra crimps in case you decide to cut any of the cables
The wires came clamped and everything ready to put on. Great Kit!
Pros: Wires Clamps Zip Ties
These are quality cables, they're just the right length for my application. This kit comes with most accessories you need for an install except a cutter & crimp tools. Would recommend this for someone who upgraded their car stereo.
Pros: Great quality, most accessories included for install. Good looks.
Very easy to work with the 1/0 gauge wire and it come pre crimped which is nice. Had to cut the power wire since my cars engine bay required only 2 ft from the battery to the alternator but with the right tools it's a breeze. All around great product for the money.
This item shipped directly from the manufacturer and Crutchfield had no communication as to whether it had shipped or not. I called XS Power and they didn't know about it but said they would call me right back. The next day I called them to get a status and XS Power stated that it was shipping from another warehouse and they were waiting on confirmation. It was finally shipped and arrived a few days later. Everyone I spoke with was very cordial. The product itself was exactly what I needed. The only problem is it cut out my sensor for battery fault. No big deal. I would recommend this product.
Pros: Large enough gauge wire to not hinder a large alternator, easy to install after you chase down existing charging cables.
Cons: Not really any Cons per say, could have come with a battery terminal and a way to connect sensor.
This is a great deal??I mean it was well set up with alot of extras.Thanks again Crutchfield for coming through with a great product and even better service!!
Pros: Everything about it!!!
great kit for setting up your vehicles electrical system. the wire is easy to mold and run and with the extra ring terminals (you must have your own crimper) can make a really clean install.
Pros: plenty of wire, extra ring terminals and heat shrink.
Cons: could use a bit larger tie-wraps.
Very High Quality Wire. Ends already crimped on. The Ground wires in Toyota are Crap. Just upgrading the ground wires has made the electrical system 95% better.
Pros: High Quality Wire.
Cons: The Power wire from Alternator to battery not long enough to go around the front of the radiator to the battery. This is how the stock wire is routed. Just have to route it differently.
The wires are quality. They were really flexible so installing it made it really easy on my 2012 Mazda 3. The 2 Ground cables were really long for me though so I had to cut one of them in half but that's not a complaint. It left me plenty of spare wires if I decide to ground other things in the engine. Overall if I had to buy it again I would.
Pros: Long Wires, Quality build, and Easy Install
Nice product, does the job that's all I could ask for :)
I would give it 5 stars but I have not hooked it up yet. Just looking at it I am happy with the quality. I was hoping the connections would be soldered but they are clamped great either way. I was also worried about cable lengths but getting it I have realized the cables are plenty long. I may change a ground out to be the power so my final ground can reach my frame.
Pros: Very strong connections for being clamped, definetly true gauge wire and it comes with plenty of cables.
Cons: Connections clamped and not soldered.
Quality stuff worth the money
I haven't installed the kit yet but it all looks like very good quality. I'm sure it will work great. Thank you.
I have a 1,200 watt amp running two Kicker Comp R's in my 2003 Accord. I realized that my amp was drawing too much power from my car and I had a slight fear that my alternator might go out. So I purchased this wiring kit which is 0 gauge wire. Easy install. Now I'm able to turn my gain up a little more and don't have to dealneith dimming lights. I recommend this product.
Pros: Easy install.
This product took longer than expected to install just because of my vehicle type, Jeep, but once on, it works great.
Pros: Ease of use, Price, Works great
Everything was great the only thing I had to so was use the longer power wire as my alternator ground to be able to run the wire in the same place as the factory. And I just used the ground that was too short as the power wire. Other than that great overall.
Pros: It helped provide plenty more power to my car!
Cons: Had to switch out the power and ground wire. Worked good still.
Nice large gauge wire, no filler insulation, it's a true 1/0 gauge. Quite flexible given it's size. Installed it in my 1983 Camaro and the amount in this kit is enough to do the Big 3 three times over on my car. I literally have about 6' of cable left over, which is a great value in my opinion. This kit also helped out with some electrical issues my car had. The tiny little factory ground and charging wire wasnt big enough and as a result, my volt meter in the car would fluctuate each time my turn signal flashed. Turn on the headlights and A/C and watch the voltage drop well below 13v. Not anymore. I can crank up the stereo (with 250w amp), all the lights and the A/C on max and the voltage doesnt move. This kit certainly does it's job.
Pros: Tons of wire with pre-crimped ends. Great Value
Cons: Needs to be cut to length and new ends either soldered on or crimped which could be difficult for someone without proper tools.
Everything you need for the Big 3 upgrade. I had plenty of cable for my installation and had about a foot left over. Very flexible 0 guage easy to maneuver around and through tight places. One end of cable is already crimped with a ring terminal and shrink-wrapped so installation was a breeze. Although not soldered just crimped, i was skeptical if it would hold but it did. I did a pull test and crimped ring terminal did not budge. The cable is very thick and i really had to work to get it into my 0 guage battery terminal, and if you have the right wire cutters its easy to cut. Kit comes with extra ring terminals, shrink wrap and even zip ties to make the install look nice and clean. Overall i am very happy with this purchase and would definitely recommend this kit to anyone doing their own Big 3 upgrade. Thanks XS power and Crutchfield for the great price.
Pros: One end of each cable has a ring terminal already crimped and shrink wrapped.
Cons: Cable was difficult to get into my 0 guage battery terminal, but the bigger the better for this instance. I did get it to fit so not really a con just a pain.
needed some wires for my high output Alternator 220amp this kit is rated at 250amp so it was perfect had all the correct tools to alter the size and mimic factory length. I would however suggest soldering the crimped wire before shrink rapping. great upgrade for your sound system.
Pros: everything is included and this is a very good price for what you get. The only way to get it cheaper is to build the kit yourself
Cons: not rated higher then 250

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your vehicle. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Kenny Feb 18, 2017 ] Staff
What do you mean do the rest do you already have wires ran to the back to connect the second battery let me know exactly what you are trying to do [ QJUAN Feb 06, 2017 ]
You have to run zero gauge wire from the battery the same way if it was under the hood. Gonna cost a lot more for sure. [ ALAN Jun 19, 2016 ]
I believe Paul's concern there was about too much power going to alternator and causing an issue with it. I don't expect that would be a problem for most alternators. [ Jeff Dec 01, 2015 ] Staff
This will allow more power to flow through your car. The wiring your car has now is very thin. The problem with doing the big three is the increase power flow to your alternator. Depending on how many amps your stock alternator is and how many watts rms you are going to be pushing will tell me more how important it is to replace your alternator [ PAUL Jan 09, 2014 ]
Lose the cap they usually don't help much. It's hard to say how much you'll benefit but you will benefit nonetheless. it depends on your alternator size and current wiring. The big 3 will more than a cap probably would. [ Eugene Jan 09, 2014 ]
Definitely get your money on the capacitor for the money you spend on a good capacitor you could by a good XS Power battery for under your hood and that would probably fix your light dimming problem. If you can afford to do the big 3 and replace your under the hood battery with the biggest Xs Power battery you can fit it will stop your dimming especially on a 1k amp. Hope this helps. Blessings!
