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

Tone Tubby 10" Baltic birch speaker 12" x 12" x 12" (rough) subwoofer with 3/4" connection. My O Audio subwoofer exploded This thing makes the room shake. I realized that the higher the voltage and W/A, the louder the sound. I use 12V, 1500mA. for the version with the case, but for $14 and for what I got thought would be less than expected (they were low) The Audio O had phasing and a fuller range (I've also used it for the bass amp in concerts. It was $300 too) but this thing is alive now and HAPPY! Sermon! The manufacturer uses clearly captured alien technology.
