Get power from USB supply, 3 AA batteries, or cell phone battery bank (power supply not included) -Output power: 3w + 3w (3 watts to each speaker) -Efficiency: up to 90% -Knob: smooth turning knob to adjust volume and turn unit on / off -Mounting: drill a hole and mount using the volume knob with the included nut and washer -Includes breakaway headers for connection, soldering required Connections:Refer to diagram picture for wiringNote: do not connect (-) or (+) speaker connections together, this will damage the amplifierNote: do not apply power without speakers connected, this will damage the amplifier

Review: Updated to 5 stars from 1 - Edit: I got the speaker working after troubleshooting. Turns out it was user error. Sound quality is good provided you don't crank it up to max where it will distort. At any reasonable volume this sounds great and is easy to integrate to any project. Obviously it's not audiophile quality but useful for odd little projects. I Will likely order more units for different projects in the future.
Review: Excellent value for money. Comes with everything for Raspberry Pi. - Bought this kit for an RetroPie arcade console I’m building. Sound is good and there is a slight buzzing sound possibly because I have this hooked to the same power source as the Raspberry Pi itself, but no other kit can beat the price. Very happy but one word of caution to potential buyers is that you shouldn’t expect very high quality sound out of this kit.

## Questions & Answers

**Q: Will this work if I only hook up one of the speakers? It mentions not to power it on if speakers aren't connected so not sure if this will damage it**
A: Great question!  Yes, it will work fine with only one speaker hooked up (I just tested the kit I have set up to make sure).  I will edit the description, thank you for your feedback.

**Q: Can the input be from a "Condenser Microphone Cartridge" or does it need to be powered source?**
A: We have never tried to connect a condenser microphone cartridge directly to the amp.  Most condenser microphones require some small amount of external power.  This amplifier works well when connected to a device with enough output power to play sound through headphones.

**Q: What is the speaker wire guage?**
A: Don't buy these, works VERY poorly, get the small square round ones with the metal (silver) speaker cones, much better sounding and you can get better/smaller amp. 24g wire, with connector on end with pins too close together...

**Q: Two speakers implies stereo, but is it?**
A: Yes, this is stereo.

### ⭐⭐⭐⭐ Can’t beat the price.
*by C***R on October 23, 2019*

I’m using this for an iot dog treat dispenser to call my dog over. It was easy to solder up. As others stated the speakers come with a four pin (I believe jst) connector and the header pins are for the DuPont style. In other words they don’t plug in. No big deal, I just put some DuPont terminals on. I was planning on shortening the wires anyways. My only complaint is there was a ton of static. I mean it was unbearable. I just wired it up to test it out and maybe it will be better once I get the finished project assembled. However I did have an aux cable filter laying around so I just threw that on for now. It completely got rid of the static, so if you have this issue I recommend picking one up. On a side note, and possibly the source of the static, I am powering the pi through the GPIO with a 5v 8amp PSU. This particular PSU is probably the source of the static, though it could be the cheap aux included. The included aux does seem to be on the lighter side as far as insulation goes. All in all, you can’t beat the price for a project like this. It definitely puts out some volume. Obviously it’s not HIFI, but that to be expected.
