Review on High-Quality 200W Bluetooth Amplifier Board with LC Filter Technique - TPA3116, DAMGOO 100W+100W Audio Amp Board: Dual Channel DC8-24V, Password-Free Connection to Phone for Peaceful Listening Experience by Stephanie Shatnawi

I bought some cheap circuit boards to test bass transducers and this unit definitely deserves a mention. Firstly it is packaged and built really nicely and looks like no other when everything is put together. Bass reproduction is better than other tested devices. Of course you can't expect massive bass from something that wasn't designed for subwoofers, but in testing this drove the AuraSound AST-2B-4 kit adequately, although it did get quite hot in the process, but if you're using smaller Dayton packs or exciters that don't have such a good bass range, this is the best stereo I've ever tried. Working Dayton 25 8 ohm pedalboard washers are really good. Note: I'm talking about using telemetry software to generate the tone. This is not suitable if you are only passing game audio for haptic feedback. For this you need a subwoofer amplifier so that you can limit the frequencies to < 200 Hz max.
