So I can send a differential signal to the rca inputs. Thanks!** A: https://www.amazon.com/SPRODIO-Converter-Adapter-summing-SC21/dp/B0BRZCGY29/ref=sr_1_1?keywords=stereo+to+mono+converter&qid=1684854327&sr=8-1 **Q: Total new to this. i have a pair of sony sscs5 bookshelf speakers. i don't see a way to add a subwoofer. am i correct?** A: You either need a 3 channel output device (most basic devices without a sub out are just 2 channels) that can run straight to the sub, or a subwoofer that can accept RCA, and split the RCA signal that would feed this amp before it goes to the amp with two RCA splitters or a stereo RCA splitter cable. **Q: Does the V3 come with a power supply? If so, which one?** A: It comes with a 5A, 32VDC power supply. It can put out 160 Watts of power (5A x 32V), not 32 Watts as another answer incorrectly states. ## Frequently Bought Together - Fosi Audio V3 Stereo Amplifier Home Audio 300 Watts x2 Power TPA3255 Class D Mini Amp 2 Channel Audio Component for Passive Bookshelf Tower Speakers Desktop Home Theater with 32V Power Supply - Fosi Audio Replaceable Control Knob Orange Controller for V3 Amplifier Stereo Amplifier Home Audio - Fosi Audio 48V 5A Power Adapter Supply for Home Audio Bluetooth Stereo Receiver Amplifier Mini Hi-Fi Class D Integrated Amp --- ## 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://belize.desertcart.com/products/535540557-fosi-audio-v3-stereo-amplifier-home-audio-300-watts-x2](https://belize.desertcart.com/products/535540557-fosi-audio-v3-stereo-amplifier-home-audio-300-watts-x2) --- *Product available on Desertcart Belize* *Store origin: BZ* *Last updated: 2026-08-23*
