Review: Hard Punching Lightweight - Well worth it. Very clean sound. No noise. Plenty of power. HINT: those 20v batteries on your power drill are perfect for creating a portable boom box project. Years before Bluetooth speakers became a thing (but after iPods) I cannibalized Klipsh, Cerwin Vega, Altec, JBL, home speakers to build boom boxes and have recently replaced the old amplifiers with these. They ALWAYS work fine. And your battery will play for hours if you are reasonable with the volume. Most folks don’t realize how much volume you can get with 1 watt/channel, 15 is overkill. Still, watch out for distortion and high end sizzle because it’s possible to overpower some high efficiency speakers.
Review: Another great wuzhi - I really like it, it's tiny, maybe 3 x 3. I have several wuzhi mini amps, and they're all great. No EQ on this one, which is what I wanted, I use it to power passive studio monitors and wanted a flat response. Lots of connectivity options.

## Questions & Answers

**Q: can you use active and passive output simutaniously?**
A: Hello, the base and the speaker terminal cannot output music at the same time. Plug in the earphones and the speaker terminal will no longer have music.

**Q: Will blue tooth quit when either usb or aux are plugged in but not being used?**
A: Bluetooth will exit. This audio power amplifier module follows the hardware priority principle. If the USB connection is successful, it is in USB mode, and when AUX is inserted, it is in AUX mode. If the USB isn't connected and the AUX isn't plugged in, it's Bluetooth mode.

**Q: What is the name of the Bluetooth signal?**
A: "Wuzhi audio".  Amp has been cranking away for 5 months with no issues.

**Q: What is the USB in jack for?**
A: USB input is to plug the USB drive to play, aux is the audio line input sound source, can not be used only with Bluetooth, the same.

### ⭐⭐⭐⭐⭐ Another great wuzhi
*by H***L on December 30, 2025*

I really like it, it's tiny, maybe 3 x 3. I have several wuzhi mini amps, and they're all great. No EQ on this one, which is what I wanted, I use it to power passive studio monitors and wanted a flat response. Lots of connectivity options.

### ⭐⭐⭐⭐⭐ Great sound in a tiny package at a tiny price
*by V***T on April 6, 2024*

Pretty easy to put together with the provided screwdriver, even though there are no instructions. I had to look at the pictures in the Amazon listing to see how and where to put the heat sink. There a little insulating sheet that goes under the pc board, with holes where there are wires on the bottom of the pc board. The underside of the power and speaker connectors extend into and thought these openings. The screws that hold the amp together raise it just enough so that they don't touch a flat surface, but if it were set on a coin or key, for example, you might get some sparks. The sound is great. I'm running it with the 12 v supply from the 20 watt x2 amp I had, that became scratchy or noisy after 10 years or so, and volume is plenty for me, with a pair of little Yamaha NS10 speakers. It also looks nice. I'm using stranded 16 AWG wire to connect the speakers, and it's a little hard to get into the screw connectors. You have to get all the strands straight. Also they are really close together, so watch out for stray strands that could cause a short. The amp is so tiny and light I had to be careful how the speaker and power wires are arranged so they don't pull it around.
