Is there any?** A: Download link for Wuzhi Audio APP for Android mobile phones: http://www.qingdaowuzhi.cn/appdownload/Wuzhi_Audio.apk For Apple iOS mobile phones, please search "wuzhi audio" in Apple App Store to download and install. **Q: There are two versions of these. does it use tpa3251 or tpa3255? what is the minium supply voltage?** A: Using tpa3251, the minimum supply voltage is 12V DC, and the current should be greater than or equal to 10A. **Q: will this amp work without the app. Or do you have to have the app for it to work?** A: I did download the app and ran it once. Never clicked on it again. Seems to be a bluetooth amp so you pair with it and it doesn't need an app. It does sound pretty great. You can easily talk with someone while extremely loud music is playing. I have low-end Klipsh bookshelf speakers and a Polk 10 subwoofer. **Q: Could I run two 5.25" woofers at 2 Ohm well/safely (paired in parallel), or do a series at 8 Ohm? Woofers have a rating of RMS 50W/MAX 100W at 4Ohm.** A: The subwoofer one way can support 2 ohms, but the stereo there is a minimum of 3 ohms, otherwise the amplifier is easily protected. Speaker resistances greater than required are fine, mainly the lower limit. You can connect speakers in series and in parallel. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by D***M on 17 December 2025* Very good ### ⭐⭐⭐⭐⭐ Good *by S***R on 23 August 2025* Good ### ⭐⭐⭐⭐ 👍👍 *by S***Y on 11 March 2026* Good product One problem no power supply inside ## Frequently Bought Together - Bluetooth Power Amplifier Board Stereo - HiFi 2.1 Channel 2X220W+350W Bluetooth 5.1 16-32V Digital Power Audio Amplifier Module Subwoofer Control with AUX/Bluetooth/USB Flash Drive (ZK-AS21) - ALITOVE 36V Power Supply 4A 144W AC/DC Adapter 100~240V AC to DC 36 Volt 4 Amp Converter 36 vdc 4A 3.5A 3A 2A Transformer with 5.5mmx 2.5mm Plug for LED Lights Inkjet Printer Laser Engraver - Facmogu 36V 5A Power Supply Adapter, 180W AC 100V~240V to DC 36 Volt 5A Converter Transformer with Barrel Connector 5.5x2.5mm & 5.5x2.1mm, AC/DC Power Converter Desktop Adpater for Home Audio 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://www.desertcart.co.uk/products/454372981-makerhawk-bluetooth-power-amplifier-board-stereo-hifi-2-1-channel](https://www.desertcart.co.uk/products/454372981-makerhawk-bluetooth-power-amplifier-board-stereo-hifi-2-1-channel) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
