My Nobsound has two separate input jacks (rca) therefore if you are intending to use this to power two speakers. then you would be advised to get a 3.5mm phono jack to two RCA plugs. I used my Nobsound to power a small 8" subwoofer through a filter (to get rid of everything above 250 hze. **Q: Could you plug a Bluetooth adapter into the aux with it being a stereo signal going into the amp from my phone and a single speaker from the amp ?** A: Yes **Q: My amplifier only has a 3.5 lineout for an active subwoofer. Can this unit be used with my passive subwoofer? Any recommendations?** A: The low frequency version should work for you by amplifying your passive subwoofer from your stereo amplifier pass-through. I have two of the full-frequency versions which I use in different rooms for powering mono centre channel speakers as tv 'sound bars'. One set up works very well but the other suffers from hum that I have not yet eradicated,. My experience chimes with reviews that suggest that these small amps can work well but are sensitive to ground-loop and interference issues in their set-up. **Q: Can I use this to power a 70 watt with 8 ohms speaker?** A: I think not. It should be like 50W @8 ohms ## Frequently Bought Together - Nobsound 100W Subwoofer Amplifier, Mono Channel Digital Power Amplifier Audio Mini Amp - electrosmart 10m Red/Black 2x 1mm 2x 89 Strand Speaker Cable Wire for Home HiFi/Car Audio etc - 4PCS Banana Cable Plugs, Audio Jack Connector, Dual Screw Lock, Speaker Cable Connector for Amplifier, HiFi, Receiver --- ## 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/61793344-nobsound-100w-subwoofer-amplifier-mono-channel-digital-power-amplifier-audio](https://www.desertcart.sg/products/61793344-nobsound-100w-subwoofer-amplifier-mono-channel-digital-power-amplifier-audio) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-16*
