Review on Nobsound NS 03G Subwoofer Amplifier Version by Paula Stewart

Works great. I got some 5.1 speakers from an old Sony 5 all in one DVD player and hooked the speakers up to a Sony 7.2 receiver and it was all plug n play except for the subwoofer which was passive (i.e. he has a built-in amplifier). To fix this, I simply placed "Nobsound NS-03G Subwoofer Amplifier 100W Mini Sub Power Amp (Black)" between the subwoofer and the receiver and adjusted the Nobsound volume to my liking. Yes, that's right. No power adapter was included, but I had an old Dell 19v 90w laptop power adapter and I just cut the connector end off and plugged in the plug (which I removed from another old AC/DC adapter) and it worked. This is supposed to be a 100w power supply, but 90w works fine in my case. For those about to rock, salute you!
