Introducing the All-New BIG ZERO 0AWG WIRE KIT – 2026 Edition!

Upgrade your automotive electrical system with our BIG ZERO WIRE KIT, designed specifically for high-output alternator installations up to 400A. This premium, pre-assembled kit makes installation easier than ever—no soldering or crimping required.

Why Upgrade?
When replacing your factory alternator with a high-output unit, the OEM wiring often falls short, leading to voltage drops and reduced performance. The BIG ZERO WIRE KIT ensures your new alternator operates at its peak potential by providing an adequately sized wire path to your vehicle's battery. Plus, the 350A fuse protects against short circuits, ensuring safe, reliable performance for your high-power accessories.


What's Included

  • 1/0 AWG OFC Red Cable – Made in the USA with 99% pure Oxygen-Free Copper for maximum conductivity.
  • Pre-Installed 5/16" Tin Plated Copper Lugs – Includes heat-shrink tubing for a professional finish.
  • Red Ring Terminal Boot Cover – For added safety and a clean appearance.
  • 350A ANL Fuse & Fuse Block – Pre-assembled and ready to safeguard your system.

Top Features

1. Super Easy Installation:
Pre-assembled components mean no soldering, no crimping, and no hassle. Just follow the simple instructions and you’re good to go.

2. Premium OFC (oxygen free copper) Cable:

  • 1/0 AWG cable offers unmatched durability and flexibility, even in extreme conditions (-49°C to 105°C).
  • Resistant to water, chemicals, abrasion, oil, and UV exposure.
  • Fully AWG-sized conductor for maximum power delivery.

3. Maximum Voltage Delivery:
By upgrading your wiring with the BIG ZERO WIRE KIT, you eliminate voltage drops, ensuring your high-output alternator delivers maximum power to your accessories.

4. Marine-Grade Certification:
Meets SAE J1127 and J378 standards for automotive, marine, and solar applications, making it versatile for any setup.


The Power of Oxygen Free Copper (OFC)

At PowerBastards, we use only 99% pure annealed electrolytic oxygen free copper cables, unlike the inferior Copper Clad Aluminum (CCA) alternatives. Here’s why:

  • Enhanced Conductivity: Oxygen free copper cables provide superior power transfer.
  • Compact Efficiency: Delivers maximum performance without needing bulky wires.
  • Long-Term Reliability: Pure copper cables resist wear and deliver consistent power over time.

Customers Frequently Ask:

1. Do I need to add ground cables?

Short answer: No — but keep reading.

Adding ground wires all over your engine bay when they aren’t needed can actually create problems. Excessive grounding can introduce ground loops, which may lead to electrical noise in your speakers, charging system irregularities, intermittent voltage issues, and unnecessarily complicated troubleshooting down the road.

Instead of cluttering your engine bay with redundant wiring, the BIG ZERO Wire Kit focuses on improving the primary current paths that actually matter. The result is cleaner voltage delivery, improved system stability, and better performance — without unnecessary complexity.

It’s also important to understand that most modern vehicles already use a chassis-grounded electrical system. The entire vehicle frame and unibody construction already exists as a common ground. Unless factory ground connections are damaged, corroded, or missing, adding extra ground wires — often promoted under the “Big 3 upgrade” religion — is typically redundant and provides little to no real-world benefit. 

In short: Fix the known weak links. Don’t add wires just to add wires.


2. Why is your cable so expensive? I can get the same on eBay for less.

Watch out — all cables are not created equal.

Most of the “too good to be true” cables and kits flooding eBay and Amazon are made from Copper Clad Aluminum (CCA). While CCA may look similar on the outside, it cuts major corners on performance, efficiency, and long-term durability.

Aluminum has significantly higher electrical resistance than copper. To achieve the same current-carrying capability as our Oxygen-Free Copper (OFC) cable, a CCA wire would need to be two full gauge sizes larger. That means bulkier cable, harder routing, poor termination, and still inferior real-world performance.

Worse yet, many CCA kits are misrepresented by gauge, poorly stranded, and prone to corrosion, heat buildup, and voltage drop — especially under high load. That’s a recipe for dimming lights, charging issues, overheated wiring, and premature failure.

Our cable costs more because it’s not cheap aluminum pretending to be copper. It’s true OFC, properly sized, properly stranded, and built to handle real current — not just look good in a product photo.

Bottom line: Real performance requires real copper.


Choose the Best—Choose PowerBastards

Don’t settle for less when it comes to your vehicle’s power. Upgrade to the BIG ZERO WIRE KIT and experience the difference with oxygen free copper wiring. Maximum efficiency, unmatched reliability, and superior performance await.

Customer brought in a Jeep with wiring they installed from ebay. Lot's of electrical problems to say the least. We ordered the 220 amperes alternator and this wire kit which worked better than expected. Will be back for more of that!

We use our trucks as off grid 4x4 campers. The high output alternator and wire kit made a huge difference in charging my batteries. Usually my batteries would go dead in the middle of the night from charging devices and heater pads. But with high output aread more

They should call it the 'BIG DIFFERENCE'
- 9/27/2024
This wire kit made a BIG difference on my mazda. I purchased this kit after installing my new alternator and the difference was OUTSTANDING. I guess it depends on your car wiring but mine in the rx-8 was tiny compared to this huge cable!
This replaces the big 3
- 9/19/2023
I was glad to find a much easier solution than the 'big 3' wire upgrade. Most cars only need to have the main battery cable upgraded which is exactly what this power bastards kit provides. This is very easy to install. I like the fuse and the wire is extrread more
