All the wires were the perfect length to run from the handle bars, under the tank and back to my left rear saddle bag. The sound is actually better than I thought it was going to be, not a lot of base but I wasn’t expecting there to be. I haven’t gone on the highway yet but as loud as it gets, I suspect I will be able to hear it just fine, even with my Vance & Hines exhaust!I haven’t ran the 2 antennas yet, 1 for FM and one for Bluetooth, and I think I might jam a small sub in the saddle bag at some point, but for now….very happy with this product! ### ⭐⭐⭐⭐⭐ Very Loud *by D***N on Reviewed in the United States on 19 September 2018* You and half the world can hear these speakers. --- ## 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.es/products/111819493-gohawk-tj4-2-1-channel-amplifier-4-full-range-waterproof](https://www.desertcart.es/products/111819493-gohawk-tj4-2-1-channel-amplifier-4-full-range-waterproof) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-05-23*
