ZK-1002T RPO 2.0 Channel Bluetooth 5.0 Amplifier Board 200W HiFi Subwoofer Audio AMP with Treble and Bass, BT USB and AUX Inputs, DC 12-24V 2.0 Channel Stereo AMP Module for DIY Speakers

Love this small mini amp, bluetooth capable and running 100watts x2 peak running at 24v max recommended volts. Love the circuitry because its advance has built in high voltage cut off so it protects the board from high voltage. Easy setup in my custom build speaker box I have in my garage. Using apache 2800, Kicker 6x9, with voltage display, charging port for battery, push button led power button. Very well built amp and for the price and sound quality it provides its a no brainer for people building custom bluetooth boxes.

Very nice amp, works very well and sounds amazing

Works great for a custom speaker system that I built for work. Provides plenty of power to my two 4" pioneer speakers using a Milwaukee 18v battery. Connecting to Bluetooth was easy and wiring was very simple and straightforward. Can't wait to build more custom speaker boxes with these.

I bought this to make my daughter a turtle box diy and worked perfectly the quality is great and sounds even better! The sound quality/ clarity To be as small as it is! If you’re planning on building one for yourself you’ll want this component! I put some thread locker in the studs when I put it together just to be save that it don’t loosen the screws. Probably didn’t have to but we did. The Bluetooth is strong and fairly good range on it. The knobs to adjust the volume / bass / treb are smooth and adjusts nicely so I was very satisfied and ran it for about 4 hours and didn’t overheat or shut down at all! Looks professional after you build it!

Used this for a diy waterproof speaker box. Works good. My only complaint is that you can’t enter pairing mode to connect with another device until the first one is disconnected, so I sometimes have to go to three other people to find out who is connected to the speaker before I can use it.

Fits and works great in a US General mini toolbox. I've used it for a few months with no issues. The bluetooth connects quick and it puts out good power. For the price it gets loud and sounds great.

I have a little project going on with this amp and its performance is amazing! The sound quality and volume can be tuned in the board or remotely through an app. I use a 24v power supply (not included) to get the best sounds quality and prevent over heating but I will still add a 40-40-10 fan to its heat sink. I used it on Bluetooth only but it does have an AUX as well. Well built product with labeling and easy to put together.

I've been using it for 5 days so far, and it works great. • The residual assembly was very easy (anyone with adequate fine motor skills should be able to do it). • I'm using my old laptop charger (19V, 130W), and it delivers more than enough power for my 4 Ohm speakers. • The sound is crystal clear, and I didn't notice any distortion coming from the amplifier itself. • Bluetooth (the main reason why I bought it). works without any issues. NOTE: the unit does not have an ON/OFF switch, so it always stays on. I will be installing a simple inline switch later to be able to turn it off when I don't need it. Overall, it's an awesome find for the price 👍

Very good product exceeded all expectations

Very nice product 👍👍

Works great some distortion when maxed out but that could be speakers or the fact I'm running it at 18v

Good sound quality
