I also heard on the 8000D that you need a upgraded alternator and at least 3 batteries total because it is very power hungry. I am going to sell my 8000D and purchase the SIA 2500. If you want to run dual power and ground inputs on the sfb-5000D then go for it. You may need an extra battery and alternator upgrade also **Q: How many channels ?** A: It’s a monoblock so 1 channel **Q: Are the power and ground inputs 0 gauge?** A: Yes, they are ## Frequently Bought Together - Sundown Audio SIA-2500D Monoblock 2500W RMS Amplifier - AudioControl EPICENTER Digital Bass Restoration Control Processor, Car Audio Bass Booster Enhancer with Wired Remote Control (Black) - Skar Audio 1/0 Gauge OFC Complete Amplifier Installation Wiring Kit, SKAR0ANL-OFC --- ## 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.ph/products/549353149-sundown-audio-sia-2500d-monoblock-2500w-rms-amplifier](https://www.desertcart.ph/products/549353149-sundown-audio-sia-2500d-monoblock-2500w-rms-amplifier) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-06*
