4.1CH Bluetooth 5.0 Stereo Amplifier, Max 800W RMS 40Wx4 Subwoofer Amplifier with Active Subwoofer Output, Hi-Fi Integrated Mini Speaker Amp for Home Theater & Karaoke, Includes Power Adapter

Works and sounds great for very inexpensive cost Subwoofer output is the best part

It works good. Connects easily to my Bluetooth devices. Great price only thing I missed out on is radio. Using it to power some exciters and volume wise, it's loud enough for my purposes.

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!

This is the best thing I’ve ever bought. My son hooked stero speakers to it. He plays his drums to the music. This is well worth the money.

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.

So, here’s my take on this device: Great sound overall, if it’s a Non-Stereo device you want (don’t recommend for car setups) ALSO another issue was the fact I couldn’t use the subwoofer upon starting up the unit unless I unplugged the input and plugged it back in. That rendered the unit obsolete for me since I’m looking for the sub bass in my speaker set up. The sub output was only one rca plug, seems as if they don’t want this device to power this unit. However if you connect the negative sub rca plug to the (-) speaker outlet, it’ll work. Conveniently sized , certainly something you can put in any sized music setup up, that’s a pro. I haven’t exactly seen the peak of the power due to the mini Pyle speakers I’m using, but knowing I didn’t have to turn the knobs to the max mean there’s more power in store for more powerful speakers. Bluetooth: So the issue here is that it seems to default start at Aux. With the position where I had the device, and the remote not exactly the most responsible, it was more of an inconvenience to keep connecting to the Bluetooth of the device. A similar yet cheaper amp had Bluetooth as a default, something a Bluetooth labeled amp should have. Also to mention the FM there’s no actual way to switch to Radio, so that’s also a bummer for someone that was installing this into a car. Quality: Pretty good on the quality side, with the exception of the wire clamps. If you apply too much pressure, the springs will come out and render the clamp useless. Once again, buy if you don’t need a Stereo set up, especially in a vehicle.

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.

I bought this for our RV that has 2 existing speakers in the bedroom with wires at the TV, but no speakers in the living room (where the TV is located). I wanted to hook up the bedroom and add 2 new bookshelf speakers. This works perfect with my TV, DVD player (using RCA cable), and my phone through BT. Great sound quality. Love the separate volume controls for each pair of speakers. I didn't need balance (left and right) with true stereo because each speaker within each pair are so close to together I wouldn't be able to hear left versus right anyway. Love that it can be powered with straight 12v for boondocking. If anything changes I'll update.

excelente por el precio y calidad, un aceptable sonido repito es un mini amplificador y también lo que nadie te dice que el subwoofers que le conectes tiene que ser activo

Amplifica muy bien mis bocinas pasivas de 8omhs

UN APARATO PEQUEÑO QUE CUMPLIO CON LAS EXPECTATIVAS

Excelente producto, tal como se muestra en la descripción, lo recomiendo.

No estoy muy seguro de recomendarlo.
