Review on Nobsound 100W TPA3116D2 Amplifier Subwoofer Digital Power Amp Board NE5532 OPAMP 8-25V: Unleash the Subsonic Experience by Kim Palmer

The original amp in my HKTS 14 subwoofer seems to have given off magic smoke. After trying to fix the problem by replacing the caps to no avail, I decided to replace the amp and found this handkerchief It's about 25% the size of the original equipment but has enough power to drive a 12" Sub Ts-14 driver (3.5 ohm inductor) The original amp was 200 watts in but that doesn't bother me at all store It lacks some features of the original but for $12 it works very well I even just use a 32w power supply from an old airport Express (so the output power is far from 100W).
