Kinda pointless when you are trying to push a 1500 watt rms sub.** A: I don't remember if it gave you an option or not sometimes on Amazon when you go to click on something there's different options you could choose I don't know why though cuz I got the same kit and I was able to get the 12 gauge that's something that the company is going to have to answer I don't have an answer for it really **Q: Is there enough wire in this for two subs to the amp?** A: Yes, theres enough speaker wire for 2 subs! However if your running 2 amplifiers no, you'd need a distro block or 2 amp wiring kits. **Q: Oxygen free cable?** A: My guess is because of the price no I was just looking for something to get me by that I could afford at the moment and they work great so but I don't know if they're oxygen free or not I doubt it **Q: Not 4 gauge wire** A: No it ain't 4 gauge wire ## Frequently Bought Together - SoundBox ECK4v2, 4 Gauge Amp Kit - Complete Amplifier Install Wiring - 2500W - Kicker 46KISLOC2 K-Series Stereo Line-Output Converter w/Remote Turn-On Output - Skar Audio RP-1200.1D Monoblock Class D MOSFET Amplifier with Remote Subwoofer Level Control, 1200W --- ## 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.co.uk/products/346139809-soundbox-eck4v2-4-gauge-amp-kit-complete-amplifier-install-wiring](https://www.desertcart.co.uk/products/346139809-soundbox-eck4v2-4-gauge-amp-kit-complete-amplifier-install-wiring) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
