Review on High-powered Bluetooth Amplifier Board with Treble and Bass Control - 100W+100W, DC 9-24V, BT and AUX Inputs, DIY Stereo AMP Board for Wireless Speakers by Steve Guillen

I used this amp along with a Flex Echo and a pair of inexpensive speakers to provide a flexible sound system for my garage. The amp worked well, it was easy to assemble and integrate. I love the fact that I can use a wide range of voltages to power it, but be aware that you need to be close to 24 volts to get full performance. The sound is quite good up to about two-thirds of full volume, as you would expect from a budget amp. Bluetooth was very easy to use. The package was affordable. Overall it works very well for what I needed and the price was right. I have no regrets buying this amp.
