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.

Length
This the how long the item is. When purchasing an item that requires a specific length (such as RCA interconnect cables or speaker wire), please make sure that the length of the item is long enough for your needs.
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.

Primary Color
This is the main color of the item.
Complies to AWG Standards
Since 1857, The AWG (American Wire Gauge) system has been the standard for measuring the diameter of wire. AWG standard is the measure of bare wire to find true gauge. Companies that do not follow AWG Standards include the thickness of the wire jacket which means the actual wire is not "True to 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.

This is the real deal. Before doing the big 3 I was having big voltage drop...I was going down to .9 wjich Iis very bad. Now I dont drop below tweleve. I advise if you have headlight dimming or big voltage drops. I will say do the big 3 (with good wire like this one) before spending alot of money on a h/o alternator

High quality

January 11, 2014

these are high quality cables. True OFC copper the connectors
Are on very secure and in case you have to shortin the cables for any reason they give you ring terminals to put on after the others are cut off. You will not be disappointed with these at all. I know I'm not and I can be very picky when It comes to car audio

Didn't have to do anything other than attach the wires were they needed to be. After watching youtube videos of what was required for the big 3 upgrade, I found this kit to make things easier.

Definitely A Must Have

August 24, 2015

I purchased this kit along with a XS Power battery. definitely the best investment I've made in a while. my car runs better with a much better throttle response. my stereo system sound so much better and so much louder, and i have no dimming lights anymore when the bass hits.

Does the job

April 28, 2016

I bought this and had friend install when I upgraded sub amp to 1400rms. Not sure if I needed or not as o stall for both was done at same time. I did not want dimming or electrical issues so I took the safe route. No dimming at all on stack electrical plus this kit. The wire is thick! Like a garden hose. Quality stuff and the connections already attached made no crimping necessary.

Great cable, worthless clips... GREAT PRODUCT OVERALL!!!

March 19, 2016

I bought this product for two main reasons, 1. it's intended purpose. Less resistance/ greater electrical current flow throughout my my vehicle.
because i was tired of dimming lights, my initial thought was to get a secondary battery but i didn't to go that route, not yet at least. It pays to do lots of research. Capacitors are not for me since they take time to charge and stay charged. Anyway This method was super easy to install, and they came pre-crimped, a big plus. The worthless clips and tiny cable straps are worthless.well money spent.

I want to know if this cable has the ring terminals installed on the wires and if it comes with extra ring terminals and heat shrink tubing?
Big-D on Jan 15, 2015
Best Answer: Yes, this big 3 kit is ofc all ends of the connection are already crimped and ready to go. It comes with extra terminals & heat shrinks. Depending on your car setup you'll need to cut the wires to shorten them. I suggest buying some extra 1/0 ring terminals from sonic electronix just in case you run out. You'll need wire cutters & a heavy duty crimper for that task. But if you think the wire lengths are exceptional then you'll be good to go with this kit.
Note : when doing the positive run to the alternator make sure the ground is off & leave the factory in place but put the bigger connection on the bottom.
Good luck with your upgrade.

I do have a question, when you install the Big 3 Upgrade, do you remove the original grounds and power from battery to alternator, or do you keep everything the same, and just add the big 3 on top the current setup?
bobby on Mar 3, 2016
Best Answer: Hi Kris,

As you can see, you've gotten an answer for BOTH possible situations. This is because, there isn't a right answer and it really all depends on You. We often recommend to just leave the OEM wiring in place - it doesn't harm anything to have MORE wiring but it only makes a marginal improvement to leave it. We've only ever removed them if they are in the way of adding the upgrade.
