ZK-502T 50W 2.0 Channel Bluetooth Amp Board with Treble and Bass Control, 12-24V DC, Bluetooth and AUX Inputs, Audio Amp Board for Home DIY Wireless Speakers

Just set this up about an hour ago. Just putting it together was worth the price. Super simple and straightforward.I'm powering it with 15v 6.33a which is enough to make get the zk-tb21 to sound really nice once I got the equalizer on it dialed in.The Bluetooth seems good to me, I've had it playing for about 90 minutes and no drops.That's like 1980s prices for an Amp. I'm in. Sounds nice

Works great! Using a 20V Black and decker electric trill battery for thesupply voltage. Using Dual LU43PB speakers, nice sounding system

This was amazing the sound was great used this to replace a bust amplifier on a Klipsch ProMedia 2.1 it sounded better than before .

Amazing little 12v (low voltage) amplifier. We use these for a bunch of various animatronics that we custom build, I've also used these in my shop and in my home. The bluetooth connection is great and you can walk away a pretty good distance before it starts to crackle and disconnect. Well worth the purchase.

One of the amps worked good and the other one had a weird static sound to it. Spend some more and get a better one.

This thing has been wonderful! I have it looked up to some bookshelf speakers for my PC and just do Bluetooth, have not had any latency issues exc. Very solid!

This is a cheap amp but it works well driving a set of monitors. I use it for an AV setup at a cabin. It is paired with a firestick and an LED projector. It is as loud as you need it to be but doesn't distort at higher volume. The bass knob definitely affects the sound. The treble is much less noticeable.I use the 1/8" jack for the audio input from the projector and When not watching TV it leaves Bluetooth open if I want to put on the radio or music. Fidelity is fine for what it is don't expect it to outperform a high-end receiver, bust its damn good.I leave it powered 24/7 and it lasts about two years before it just stops powering up. It's a good option for a bit of sound to power some old speakers. I'm sure this is branded under several different names but the images and parts layout is all the same.

I recently purchased this Bluetooth amplifier receiver, and overall, I'm quite impressed! The sound quality is excellent, providing clean and clear audio for my speaker build. Pairing it with my devices was a breeze, and the Bluetooth connectivity is stable from 100 feet or so away!!!
