Review on WINGONEER TPA3116 2x50W + 100W 2.1 Dual Channel Power Amplifier Board for Subwoofers, Digital Audio Amp, DC 12V-26V by Christopher Tillman

Bought because the driver board in my Logitech z623 started making a little noise. I've now installed it with two Onkyo bookshelf speakers and an old Logitch subwoofer (original satellite speakers were junk) powered by an old laptop power supply. I can turn it all the way down without playing anything and there is only a slight hiss, but nothing compared to my old setup. The hottest it has ever been was 95°F or 35°C. It had issues with another cheaper driver that felt hot, but this one stays very cold. Sounds better than a $100 2.1 system so I'm happy with that. Eventually I will make a wooden box to house it.
