This amp is amazing. The other amp I had made my headlights flash when the speakers hit hard and they didn’t sound all that great. With this amp, my headlights don’t flash (that I’ve noticed) and the subs hit hard and sound good. I still need to fine tune it but with a quick tune it’s a night and day difference. Long story short, buy this amp. Later, I plan to get better quality subwoofers to give me what I’m looking for but for now I’m happy. Nicest quality amp I’ve ever had and it’s small enough to fit under the back seat in my truck. I can’t rave enough about it, I’m so happy right now! Upon further listening I’m pretty sure one of my subs is blown.

Udgrading soon #sendit ### ⭐ HORRIBLE electrical noise and feedback *by T***R on 17 June 2026* I purchased an SFB-1000 v2 as a replacement for my previous amplifier and immediately began experiencing severe electrical noise and feedback through the audio system. I spent countless hours troubleshooting the issue. I checked grounds, power wiring, RCA cables, gain settings, signal sources, and other components throughout the system. The most frustrating part was that my mids and highs amplifier worked perfectly using the exact same wiring and RCA connections. After extensive testing, I replaced the SFB-1000 v2 with a different amplifier. The electrical noise disappeared immediately and the subwoofer output returned to normal. No other changes were made to the system. Based on my experience, the amplifier was introducing noise into an otherwise properly functioning system. What should have been a straightforward installation turned into a lengthy troubleshooting process and significant wasted time. I cannot recommend this product based on my experience. ## Frequently Bought Together - SFB-1000D - Sundown Audio Monoblock 1410w RMS Amplifier - Skar Audio 4 Gauge OFC Complete Amplifier Installation Wiring Kit, SKAR4ANL-OFC - Sundown Audio SML-12-D4 12" 500W 4-Ohm Shallow Subwoofer --- ## 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/444618679-sfb-1000d-monoblock-1410w-rms-amplifier](https://www.desertcart.co.uk/products/444618679-sfb-1000d-monoblock-1410w-rms-amplifier) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-07-01*
