You can simply use a hammer and a blunt chisel to crimp the terminal end into place onto the copper wire after using a utility knife to remove a section of the protective casing, after you cut your wire to the length you need for your vehicle. **Q: What fuse can I use for this wire??** A: I would use at least a 250 or 300 amp fuse. This wire is massive! **Q: What size is the ring opening 5/16 or 3/8?** A: Know this is late. But last time I checked 1/16+3/8=7/16. (28/64). ***3/8+1/64=25/64**** With small fluctuations in thickness of the insulation, I would disregard that 1/64 as it pretty minuscule, and go with 3/8. We’re not building a motor here to need one hundredth or thousandth of an inch measurement increments. ## Frequently Bought Together - GP Car Audio Big 3 UPGRADE wiring Kit OFC TRUE 1/0 AWG GAUGE GREEN and BLACK - mankk 166 Pcs Wire Ferrules Kits Silver Plated Copper Crimp Terminal Connector 8 Sizes AWG (1/0 2/0 2 4 6 8 10 12) Sleeves Insulated Cord Pin End Terminal M-020 - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing --- ## 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.tn/products/103720635-gp-car-audio-big-3-upgrade-wiring-kit-ofc-true](https://www.desertcart.tn/products/103720635-gp-car-audio-big-3-upgrade-wiring-kit-ofc-true) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
