I had about 70 miles on my 07 electraglide and the amp gave out. I surmised - maybe fuse - but no. Then after my 2000 mile trip, I figured I'd come home to find a wire loose or something - no. Amp powers up, light blue, no sound. Checked every connection, checked input, but no output. It is a lot of work to wire this into the fairing, then to troubleshoot, only to find out it's garbage --- ## 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.sg/products/128532773-gravity-gbr500-2d-true-300-watt-rms-micro-ultra-compact](https://www.desertcart.sg/products/128532773-gravity-gbr500-2d-true-300-watt-rms-micro-ultra-compact) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-08*
