Review on 🔊 MakerHawk 2Pcs TPA3116D2 Two-Channel Stereo Amplifier Board: 2x50W High Power Digital Subwoofer Amplifier for Store Solicitation, Home Theater, Square Speakers DIY by Ricky Pee

Update: RMS tests were run on two of these amplifiers and both showed well under 50 watts per channel. The best I've been able to get is 8W RMS with a fanless heatsink and 16W RMS per channel with a high airflow fan. The amp works, but due to the small size and location of the heatsink, you can't replace it with something bigger. Tested with this amplifier at 24 VDC. more watts per channel and the amp will go into thermal shutdown mode. With a good fan, we managed to get 16 watts per channel. The small size of the heatsink is too small in my opinion and due to the position of the heatsink there is no way to fit in the larger size unless you can find a heatsink with higher fins.
