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 Tony Weber

Expensive for such a price. It's perfect for any DIY speaker projects. Taking full advantage of the 24V input cable will greatly increase the power output of the amplifier. Without sacrificing loyalty. Once you understand how to properly apply a crossover, amplify the stage, and choose quality speakers for your build, this amp will be even more effective. To test the amplifier, I connected two 12V 7Ah batteries in series as a power source. Total 24V 7Ah. I connected each channel in a 4 ohm series-parallel circuit. Featuring Dayton Audio ND91-4 3 1/2 drivers and some tweeters with built in 5kHz high pass crossovers. At around 70 watts RMS per channel, with the amp delivering a full 100 watts per channel, I could easily blast these speakers. Once I add another Dayton Audio on each side and finish building the case, this project will have the perfect power output. This is definitely my new amp for DIY projects. My only 2 complaints are that there are no indicator markings on the knobs and the left and right channel outputs have to be in opposite positions.
