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.

Few things. The subwoofer plugged in needs to have its own power or it won’t work. As well as I haven’t figured out the FM portion yet, any help would be appreciated.Other than those two issues I had, on my end, the device is solid. Good sound, loud, powers 4 speakers, 2 left and 2 right. With each set of left and right having their own volume control. Bluetooth super smooth so far and the bass and treble do also work on your speakers! (Using 4x klipsch desktop speakers 2.1 thx certified w/o sub for now)All in all, this is an awesome device that might take a little configuring but well worth the money and time spent figuring it out!

We have a need for a Bluetooth-enabled amp that accepts two pair of bare-wire speakers in two rooms at our German club, with independant volume control between each room. This fits the bill. It was an easy install.The reason it does not get 5 stars is due to some nits:- #1 is that the remote is weak. It does not work from far away, and only works if it is straight-on. This makes it a bit difficult to control volume and MP3 skipping from our bar area.- I can't figure out how it determines what to play from the USB key. It is alphabetical? Is it random? Changing the folders names doesn't seem to change that order. Haven't tried randomizing file names yet.- I note that if you power off with the remote it will play MP3 from where you stopped, but if you power it off with the knobs it starts from its beginning, wherever that is. As expected.- Bluetooth input (say, from an iPad) is significantly lower volume than the USB stick MP3s, even though it's the same MP3s. That's a problem if you're playing from BT then your source dies; it'll switch to *VERY LOUD* from the USB stick and then you're scrambling to get the weak remote to lower the volume.- I'd prefer a single volume control with a fader/balance versus dual-volume controls, but that's a preference.Like I said: nits. This works for us, and it's a helluva value for what it does. We'll figure out its foibles and work around them.

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.

Power supply fries as soon as its plugged in. I saw blue lights for a second and then nothing. I had to find a different power supply to check the amp. I will be returning it due to that and the ridiculous turn on noise.

OK, first, let's get the usual out of the way. Yes, it's a neat little amp that does what it says. No issue there.However....For those looking to buy this amp to use WITH a powered subwoofer.... there is a caveat. It can ONLY be controlled with the remote, NOT the front panel volume dial. This was not clear in the description and may or may not matter to you depending on how you use the device.I currently have an original Lepai amp that has served me well. But I was looking to upgrade my setup and add a powered sub. I needed an amp with a powered sub out. So I ordered this one, bluetooth was a nice bonus. (Works well, btw.) The ONLY thing I hate about a lot of bluetooth devices... why is the "connect" sound at earth shattering volume even if the volume is turned down???Now for the problem "I" had. The front volume knob as you expect, controls the volume of the speakers. All fine. However, it does NOT control the sub out! I plugged in the sub and almost launched across the room!It turns out that you MUST use the remote (which is kind of crap) to control the sub AND overall volume. This is an odd design, making the use of this amp awkward to use if on your desk or in reach. Why not just turn the volume knob??? Nope, you MUST use the crappy remote which will inevitably break, NOT the front volume knobs.This is ONLY a dumb design issue IF you need a powered sub out. I could modify the internals to fix this for my use, which would also make more sense.... but why? I paid for a "working" product. Any other amp will control the sub out with the regular big volume knob as you would expect. Because of this, and I don't wish to use a remote to control something 24" away from me, I returned it.Just be aware of this design issue. Otherwise.... hey, it works great!

This amplifier was exactly what I needed for my pool patio. It is compact and has 4 channels that drives four speakers in the pool and covered patio area of my back yard. I can operate the speakers in the pool area or patio area with two control knobs that gives us the sound we want in the areas we are in. The Bluetooth option allows us to run Pandora with ease and the remote comes in handy. I highly recommend this amplifier.
