100W+100W Amplifier Board with Treble and Bass Control, DC 9-24V, BT and AUX Inputs, 2.0 Channel Stereo AMP Board for DIY Wireless Speakers, Password Free (ZK-1002T Black)

I’m impressed. Great little stereo chip amp. Unlike some of the bare boards I’ve been testing, this is enclosed, well protected, nice isolated screw terminals, a standard socket for power adapters. Bluetooth is icing on the cake, and works fine. (An antenna is provided, haven’t connected it yet.) I haven’t yet compared the built in BT with my separate receiver through the provided aux port, but sounds fine at first try. Plenty of power into my 8ohm speakers. Definitely recommended.

We’re good for my project

I bought this amp board to add Bluetooth audio to my tractor cab instead of installing a full head unit, and it worked out better than I expected. I paired it with a small 24V to 12V converter and a set of basic speakers, and Bluetooth connection has been reliable so far. It reconnects quickly when I start the tractor back up, which was one of the things I was hoping for. Volume is more than enough inside the cab, even with engine noise and mowing. The board itself is compact enough to tuck behind a panel without taking up much space, and the screw terminals made wiring fairly straightforward. Sound quality is surprisingly decent for the size and price. It’s not some high-end audio setup obviously, but for streaming music and podcasts while working, it does the job well. A couple minor downsides: the instructions are pretty minimal, and you’ll want to mount it somewhere protected from dust and vibration long term. The Bluetooth voice prompts are also a little louder than necessary. Overall though, this ended up being a simple and inexpensive way to add Bluetooth audio to equipment that didn’t originally have it.

Worked great for both my builds on the Apache cases!

Great amp if you dont care about a speaker being loud. The amp running at 24 volts starts distorting at about half volume. Sounds terrible after. Up to half sounds great.

I used this one in my boombox build and it puts out plenty of power for a pair of 6x9 speakers. Unbelievable sound quality for this price. Easy to use volume controls and seems like it's built plenty sturdy.

For the money this thing is amazing. Not the greatest range but it just works. If you have some old speakers that are outdoors or somewhere that just need a nice input for the money. You can't go wrong with this. For anyone looking to do a homebrew version of Sonos or some kind of smart home streaming solutions, this is a pretty valuable item

Worked great
