Review on Powerful 200W Mini Mono Subwoofer Amplifier - Fosi Audio M03: Full-Frequency and Sub Bass Switchable, Perfect for Home Theater & Single Power Subwoofer by Amy Silakos

Just received I will update this review in the coming days. It was pretty easy to set up, no instructions required. First thing I noticed was that it would randomly shut down after a few minutes and had to press the power and on button to get it working again. I'm hoping it's because I only connected the left RCA channel since the subwoofer only has one output from the receiver. I've since connected the right side, but it's just an empty wire going nowhere. It seems to stay enabled but doesn't make any sense as to why. Let's see how reliable it is. I hook it up to a 12" Kicker Pro subwoofer I had in my car a while ago and now use it as a powered subwoofer for my entertainment system. At home In terms of performance, this little thing seems to pack quite a punch have that's great I don't understand why it's not very hot when it's running I remember my car amp getting pretty hot when I pushed this subwoofer if anything it pushes the Kicker Pro subwoofer the I quite have. I wish it had more modern features like Bluetooth connectivity as well as the ability to connect more speakers to it. It would also be great if the crossover had an indicator of which level is more accurate. setI've emailed the Sent to fosi support and haven't gotten a reply yet.Amp update still randomly doesn't work until you turn it off and on again.When it's in it works great.I've emailed fosi support t sent and they asked for a video of the problem which I sent. Downgraded to 2 stars due to unreliable amplifier. I may update the rating based on progress. February 21 update. Definitely something bad as these amps happen to stop working and the only way to fix this is to cycle power. I recently connected one of the apps, a simple bass converter. It suddenly stopped working. I wish I could buy another brand that still works
