DIY Speaker Kit - PAM8403 5V Amplifier + 2Pcs 4 ohm, 3 watt Speakers - Mini Class D Digital Audio Amplifier amp Board Module kit for Arduino - Everything You Need, Includes 3.5mm Plug!

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.

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.

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.

Installed this in a weather proof SS enclosure at the end of my driveway to work with my audio intercom. Surprisingly loud and clear! I was impressed! Bought two sets, in case one croaks down the road.

While I could’ve choosen another product, I still purchased this which would’ve been the same thing, but just with extra speakers. Straight forward if you have done this before, or if you just do some research. My solder work is pretty rough, but if it works, it works! Only thing was that on the photos where it tells what wires to put (the 3.5mm wires), it was not as it was in the photos. Yellow was left, black was ground, and red was right (see in photos).

About what you would expect for the price point. Everything works. Would have got the job done other than the noise levels when using an arduino are too much. My configuration was serial communication to a dfplayer sac to amp amp to speakers. Tried adding 1k resisters on the tx and rx, made sure grounds were good but could not get rid of the pulsing noise when it played an mp3. Remove the amp and put the speakers on the df player and there are no issues.

Amplifier good, speakers not worth the money; volume level and quality is poor. Tried to correct with isolation, ended up using 1" silver speakers with this amplifier, MANY times better, louder and much cleaner. The plug on the speakers DOES not fit on the pins of the amplifier - stupid!. the RCA output has bare wires, should have connectors for amplifier for this to be a sensible package.

Setup unit as intended, I am an electronic tech, this device did not work out of the package, not bothered with returns as it would have cost more than what it was worth.
