AK-380 USB SD BT.C FM AUX Audio Power Amplifier 400W+400W 2.0 CH HiFi Stereo AMP Speaker Bluetooth 5.0 Amp Receiver with 12V 5A Power Supply,FM Antenna for Car Home Bar Party

Great value for the quality, I use it to power outdoor speakers. Sometimes it’s left powered on outside in the elements for weeks at a time and still works great. Installing and connecting wires is very straight forward. Noise level isn’t bad but not nightclub loud, Bluetooth range is about 30-40 feet

Simple design, great value easy Bluetooth connectivity compact yet powerful, sound can easily be dialed in to your preference

When I first reviewed this, I gave it a one-star. Why the change? I thought the amp was DOA. I tried two brand new speakers: Nothing. Changed the speaker wire: Nothing. Ordered a Pyle amp because I thought this was DOA. I never suspected that I could receive two DOA speakers! (DUAL item #B000A5S926) I apologize to the manufacturer for the initial bad review. They offered a refund, which we could not accept because we had installed this amp offshore and could not get it back to the US. Good on them! I would not say that this is as good as my Pyle amplifier that I have had for 7 or 8 years. But it is decent. It has lots of options that we will probably never use. But bottom line is: it works. It would be nice if these little amps had a Left/Right balance control. Even the new Pyle does not have that. Wish list.

For the price , you get what you pay for . Works great and can turn up and down by left and right which is nice but also annoying. Sound quality is good until you go too loud but again, you get what you pay for .

Update: Arrarown took care of the missing remote, good customer service. the S-299 Bluetooth 5.0 Power Amplifier and was excited to get it set up with my home speaker system. Installation was straightforward, and the sound quality so far has been solid for the price—clear output, good Bluetooth range, and it powers my speakers well. However, I was disappointed to find that the remote control was missing from the box. It’s a small thing, but it makes a big difference in daily use, especially since the unit is now installed and not easily accessible. I’m hoping the seller can send a replacement remote so I don’t have to go through the hassle of uninstalling and returning the entire unit. Otherwise, it's a good product and does what it promises. Will update my review if the remote situation is resolved.

Needed something small that could drive my speakers at my office so I gave this system a shot as it was so inexpensive. Got it in, unboxed it, plugged it in, and hooked up my Micca Bookshelf Speakers. I was floored at the power of this little amp, the clean sound (no hums or ground loops), and the ease of use. It’s quite impressive. With the capability of screwing this in under my desk and running cables over the back, it keeps my desk clean and gives me solid sound. The functionality of the Line In is clear, the Bluetooth is easy to access and pair, and the radio has a decent pickup capability when the included antenna is plugged in. It’s a really great system for the price and the size is absolutely perfect!!! Can’t wait to try it with a couple of deep full range speakers later this week!!

My requirements: Small, Light weight, sounds decent, cheap. Be prepared with a powerful magnifying glass if you want to read the manual, which is written in transliterated Chinese. Power cord is 3' long. There's no cord supplied for the 12V power input, so this was not tested. Knobs are black with a black notch to indicate the position - very difficult to read. The unit forgets the FM station when turned off. The unit shipped with the volume knob turned to max. Be careful with that initial test!!! Line input is RCA, and outputs are the old wire clamp method. Remote control uses a 3V CR-2025 watch battery (supplied). The volume buttons on the remote were confusing - they allow you to change the volume up or down UP TO THE SETTING OF THE VOLUME KNOB on the device. Bluetooth worked, but seemed to require a higher volume setting than radio or AUX input. The manual is silent on what type of microphone can be connected. I used an ancient Realistic Highball-7 (impedance 600 ohm) mic that was at the bottom of a box of unused gear. It worked OK. Couldn't get music to play from a USB memory stick at all. It just didn't recognize it. Using an old SD card did work. Is it possible that the player doesn't recognize newer types of USB sticks? USB sticks are typically compatible with older devices that try to read them. Luckily, playing from USB sticks was not something I need to do with this device.

This is a 5 star item for value sound quality and loudness however after having ordered a four channel unit and it came with Four sets of speaker terminals on the back only two of them worked. I tried speakers that were proven to work on two good channels on the two bad channels and they did not work. It is hard to find an affordable 4 channel stereo amplifier so I'm disappointed also Bluetooth was not just problematic I couldn't get it to connect but I know that's just ABT issue and it could be the player not this device If you want good sound and are happy with two channels save a buck and buy the 2 channel model As for me I went with a different brand and am using wire adapters to connect my 4 speakers to these two channels that will come on the new unit. This housing is plastic not aluminum also.
