Facmogu S-299 4.1CH Bluetooth Power Amplifier with Active Subwoofer Output (NOT Passive Subwoofer), Max 800W RMS 40Wx4 Subwoofer Amplifier Hi-Fi Integrated Mini Speaker Amp Audio Sub Bass Amp

I bought this to use as the amp on my little Burning Man art car. I kept it in a 1 gallon zip lock bag to help it survive the dust. It worked flawlessly. I didn't use the remote. It handled two weeks of rattling around in a hot, dusty, even a little rainy, desert. I ran it at the highest volume I could (about 80%) before distortion. I put about 100 hours of run time on it. The sound was as loud and clear as I had hoped for out of this little unit. I'd say it's loud enough to blast a large living room, or nice backyard system.

I bought this to use in my non-heated/cooled workshop and it has been going strong for a few months now. I do agree with other reviewers that the connection noise it makes when turning on can be a bit annoying but is the only issue I have had. I just make sure its turned down when I power it up and connect any Bluetooth item to it. The item has worked great when I'm working my my shop or doing yard work with the rollup door to my shop open and does not take up much room at all. So far I would recommend it to anyone looking for a good-priced amplifier.

Just hooked it up to my TV audio out, powering two speakers and the sub woofer and it works fine, good clear sound, nice and quiet, no hiss or noise. It doesn't have a mute setting on the remote, but just power it off and it will do the trick.Speaking about powering off, when you do, the display turns off, however, the bright blue LED light at the knobs stays on! It takes a good power outage to realize how much light there is in your home from all the LED's in your stuff. I might open the case and disconnect the lights at the knobs, or I might just bask in the warm glow of the parade of LED's in the room!

Running a 15.4.4 DFX system from my Sound blaster AE-9 audio card in PC with 384kbps processing. And Dolby Digital and DTS enabled.I needed this breakout box to separate my rear speakers. I'm running 2 Rockville Towers and a 12" Rockville subwoofer up front. And an SVS Sledge sub with 325W amp, Klipsch reference speakers and a great pair of Aiwa bookshelf's I've been using since the 90's. Atmos speakers are Klipsch reference as well.My system sounds amazing!!! This fit exactly what I needed. And the independent control and sub out jack were a nice bonus for the price.

NOT STEREO! it is 4 channel mono, no balance control, and no stereo separation. i tried using audio test gear to make sure i wasnt losing my mind, it is MONO ONLY! going back. the description is bs.

For the price, this is a neat little amp for use in like a den for bookshelf speakers or a garage. The main drawback I found was that when you power it off, each time it restarts it starts as Line-In and if you want Bluetooth, you have to manually change it each time. You cannot just set it an forget it. And the sound it makes when connecting to Bluetooth is extremely loud, you have to turn it down when getting to Bluetooth, then set the volume back up. Another drawback is that it comes with an IR remote and not RF. So, you cannot hide the unit out of the way because you have to point the remote at it to use it.

I have this hooked up to 4 speakers and a subwoofer in my garage. Use bluetooth to attach my computer and Line-in for my TV. Works great.

I have an old car with a single speaker in the dashboard. It has a working Becker Europa radio that I want to remain in the car. I bought this amp after searching for one that would output mono sound (not stereo) and used 12V power. (Many amps now can use 12-36 volt input and only produce top wattage if the power is 24 or 36volts) The power is way beyond what I would ever use in a car, but consider I'm not the person driving around with thundering bass and the windows vibrating. Perfect to use in an old vehicle with single speaker.
