S299 Max 800W Bluetooth Home Audio Amplifier, RMS 40Wx4 4.1CH Bluetooth Power Amplifier with Active Subwoofer, Sound Audio System w/AUX, Headphone Jack, USB, SD, Remote Control - Suacopzar

For a cheaper product it sure works good. I've got several subs and some loudspeakers hooked up to it and it makes my garage sound awesome.

I tested this with two different sound systems, the first is a Bose 5.1 home theater system (I only used two speakers and the sub) The second is Polk Audio floor standing speakers and sub. I did not test both channels (4 speakers) simultaneously. Also, I only tested the Bluetooth as opposed to AUX/USB.Bluetooth works well and paired with my iPhone without issue. Now for the misleading descriptions, however, keep in mind this amplifier is about $50 dollars at time of review:Sound quality is not what I would call hi-fidelity. Sound reproduction is okay at best. I own a Yamaha receiver which produces more clarity than this amp. The manufacturer claims you will have clear sound without any distortion. This is simply not true. Once past 50% on the volume knob distortion is noticeable and very noticeable at full volume. Which brings me to the next point, there is no way this amp is pushing 800 watts. At full volume it would have destroyed my speakers, but it did not. That’s about it for the misleading descriptions.Other things I discovered, the amp is very lightweight and can be fixed (by using your own screws) to a wall cabinet etc. Both subs used during testing pop when the amp is powered on or off. The equalizer (on the remote) cannot be used in Bluetooth mode. The remote will not turn the amp on if the volume button is all the way down (which completely turns of the unit). Using the remote to turn of the amp results in the dial’s backlight to stay illuminated.Overall, I like this little amp and it’s very affordable as far as amplifiers go. I’m using it in my workout room and this amp is replacing an old audio receiver that does not have Bluetooth capabilities. I’ll update this review if I experience an issues.

Very good

It works but there is no sub control other than for you a/b speakers and the sound quality it emits is borderline garbage 10/10 would not recommend

A decent amount of features/connectivity for it's price range. Sound was as good as other amps I've tried, that's really going to depend a lot on the speaker you hook this to and the quality of your source signal.AC adapter is 12v 5 amp, so 60 watts total power is what this can pull, I don't know where they're getting this 800w from, maybe it's able to pull vacuum energy from empty space, if so I'd think they'd be charging much more. AC adapter cable is 6ft long.

The amp, gets warm. i mean warm just give it breaks and your alright . i have mine in a trunk on a bike .some air ways in the bag is the next project. pretty good power for light jobs , i gave 4 stars. ty

To get what is advertised mean no bass and ear ringing. There are way better products at lower wattage

I had some old speakers that were part of my old surround sound system. I hooked them up to this little amp and was able to bring them back to life! I didn't have a subwoofer to hook to this, but it still sounded great with the 2 large speakers I used.What I like1. Plenty of umph! I turned these up half way and it was very loud. I didn't want to go higher then this or I fear I'd break the speakers2. The bluetooth connection was very simple. I synced this to the TV it just worked. You can hook two bluetooth devices to it.3. Feels very firm and solid. What an amp should feel like4. A REAL power plug5. 4 speaker output + subwoofer.What I didn't like as well.1. No surround sound2. No stereo sound. Yes it's 1-channel. It'll power 4 speakers with the same output.3. No optical-in (probably because of #1)
