It's some of the thickest 1/0 awg avaible. I almost bought skyhigh but decided to go GP this time. The only downside is that the wire isn't as flexible as skyhigh but it has thicker insulation which is very important when you're running wires underneath your hood. It's also heat resistant up to 225 degrees , oil, gas, cut, tear and acid resistant. I've notice a big difference in the performance of my kicker kxa1600.1 amplifier. If you plan on doing this make sure you fuse the positive wire from battery to alternator. Also make sure your battery is unhooked before you even start this task. GP is what you need under your hood. Tip: The big 3 consist of 1 Battery + to alternator +. 2. Battery - (ground) to chassis 3. Engine block ground to chassis. 4. Bonus: alternator ground to battery - It's now the big 4 upgrade Do not replace wire, just add to the existing wire. ## Features - 1/0 OFHC Copper wire MADE IN THE USA - Pure copper lugs MADE IN THE USA - GP heat shrinks MADE IN HE USA - 3 4ft runs of wire crimped on one end, 1 power 2 ground - Orange power, black ground ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075ZJF4PH | | Best Sellers Rank | #376 in Car Amplifier Power & Ground Cable | | Brand | GP Audio | | Brand Name | GP Audio | | Cable Type | car audio power and ground cables | | Color | 1 Orange, 2 Black | | Compatible Devices | Car Audio Amplifier, Car Speakers | | Compatible Phone Models | Potentially compatible with smartphones via car audio systems, specific models unknown | | Connector Gender | Male-to-Female | | Connector Type | Male-to-female | | Customer Reviews | 4.8 out of 5 stars 202 Reviews | | Indoor Outdoor Usage | Indoor, Outdoor | | Manufacturer | GP Audio | | Maximum Voltage | 12 volts_of_direct_current | | Number of Pins | 3 | | Part Number | GP Big 3 1/0-O | | Recommended Uses For Product | Automotive | | Unit Count | 1 Count | ## Product Details - **Brand:** GP Audio - **Cable Type:** car audio power and ground cables - **Compatible Devices:** Car Audio Amplifier, Car Speakers - **Compatible Phone Models:** Potentially compatible with smartphones via car audio systems, specific models unknown - **Connector Type:** Male-to-female ## Images ![GP Car Audio Big 3 UPGRADE wiring Kit OFC TRUE 1/0 AWG GAUGE ORANGE and BLACK - Image 1](https://m.media-amazon.com/images/I/81yMWt9JuqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ True 0 gauge *by E***W on January 13, 2026* Great product ### ⭐⭐⭐⭐⭐ Best wire for big 3 *by S***. on February 13, 2021* This wire is worth every penny.

It is put together nicely and I like the double jacket on the wire. It appears to be quality wire and have a quality jacket. I received plenty of wire to complete the install. Engine to battery negative, frame to battery negative, and alternator positive to the distribution center main connection. I had a 0 gauge amp kit with 20 foot of wire to install, so ran the positive to the distribution center and then another positive from the distribution center to the battery. This was most convenient for me. I had purchased battery clamps that included two 0 gauge connections and two 4-8 gauge connections each. I really needed 3 0 gauge connections in the positive to make this work correctly. Not a fault of the kit, just an oversite of my own. I would buy this kit again and may purchase another when I get ready to install my winch kit on my F-450. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/103720866-gp-car-audio-big-3-upgrade-wiring-kit-ofc-true](https://www.desertcart.gr/products/103720866-gp-car-audio-big-3-upgrade-wiring-kit-ofc-true) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-28*
