Review on Nobsound NS 03G Subwoofer Amplifier Version by Latoya Harper

I bought one of these and used it to power a bass shaker under my office/gaming chair. In this capacity it worked fine for a year, but then stopped working even though the lightbulb was still on. EDIT: This turned out to be a bug coming from the amp, not a bug in the amp. The amp does a good job as long as all the wiring is in order. However, the unit will generate sparks if the power supply is plugged into the wall before it is plugged into the amplifier! watch the video This also happens when the device is switched off. This behavior appears to be intentional (there is an advertisement for it in the printed manual), but not what I expected. I don't expect this to be a major safety concern, but I believe a different circuit or power connection can fix the problem, so worth a star for me.
