## Questions & Answers

**Q: The power amplifier is connected correctly, why is there noise such as electric current?**
A: Please check whether there is current sound when no load. And confirm that the surrounding current signals will not cause interference. Please make sure all the cable completely pushed into the device, incompletely connections will create distorted.

**Q: Why only one channel work ? Is it defective?**
A: Since the amplifier is not used alone, it needs to be used together with other electronic equipment, so it needs to be ruled out one by one! Are the positive and negative wires connected to the speaker connected together?

**Q: If you find that the Bluetooth connection is unstable, you can try the following steps to solve it.**
A: Make sure there are no obstacles (especially metals) blocking the signal. Turn off the power amplifier, disconnect and clear the connection of the Bluetooth transmitting device, and try to reconnect.

**Q: Can you connect two devices with bluetooth?**
A: No, connecting two at the same time will cause the audio stream to be disrupted. It can only be disconnected and then connected to other devices.

**Q: How to connect to a bluetooth speaker?**
A: The Bluetooth speaker is a Bluetooth receiver, which is the same as the Bluetooth function of the power amplifier, and the Bluetooth speaker already has a small power amplifier, which may cause burn-in after being amplified by other power amplifiers.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little unit (and little is a good thing)
*by A***6 on December 27, 2020*

Surprisingly good for the price. The only thing missing is a headphone jack but...it's a little power house and well drives my bookshelf speakers. It has presets and the Bluetooth connects easily and as expected. I'm going to mount this under a top cabinet in the kitchen. Don't expect much from the manual as it is written in very broken English but you can still figure it out. It also comes with a standard AC cord so you don't need to fuss with a DC wall wart. It comes with a small remote as well.You can't go wrong for the price. FYI - In the rating questionnaire it asks about "Sheerness". I have no idea how that applies here.P.S. - I have a few additional comments regarding this item after reading some of the other reviews.1. Quality - some folks have had issues after running the system. Since my review was written days after receiving it, I can't comment except to make sure you put it in a location where airflow to the unit is not blocked. So far, my unit is not getting hot.2. Sound quality - Folks, this unit costs $45 dollars. If you are and audiophile and into studio quality sound, then I think you are expecting a bit much for $45. I'm a music lover and it sounds plenty good enough for me. I've listened to YouTube music videos and some FM music stations and it sounds pretty good to me. It does go louder than I need and I get some decent full bass sounds from my bookshelf speakers. If you expect 130 db rap or pounding rock or the fine nuances and dynamic range of the 1812 Overature, then this unit might be for you.But aside from the long term potential quality issue, I'm quite pleased with the unit. If you are happy with the quality of music over your cell phone, this will do just fine and my wife is happy listening to Bocelli over this unit.So, since I've already belabored this issue, I'll repeat, for $45 you get a very small unit that sounds pretty darn good. Oh, and yeah, the controls seem a bit weird at first but since the unit is small, 20+ buttons simply won't fit on it so they've overload some of the buttons with more than one function which is not big deal after 10 minutes of acclimation. And then there's the remote. The first time I tried it didn't work either but just press the button a tiny bit firmer and it works fine.Lastly, if you plug this into cheapo speakers, it will sound crummy. Buy a $1000 receiver and plug it into a $99 dollar speakers, it'll sound lousy. So make sure your speakers match your sound expectations.The End

### ⭐⭐⭐⭐⭐ Big Value In A Small Format
*by V***N on March 24, 2021*

I purchased the "Sunbuck Wireless Bluetooth Stereo Amplifier System – 180W Dual Channel Sound Power Audio Receiver w/USB, SD Card, FM Radio for Home Speakers (25BU)" after reading reviews and finding the features ideal for my home installation.It has a very small footprint which is ideal where space is at a premium. Controls are simple and intuitive. Knobs for volume, bass, and treble operate smoothly and precisely. The remote works well, but its diminutive size will encourage getting lost. I find the connections and construction to be of surprising quality for such a value added amplifier.I drive two Wharfdale Crystal 10 bookshelf speakers, which it handles with ease. My inputs include a CD player and Bluetooth sourced from my phone. Sound quality and Bluetooth connectivity are excellent. It would be nice if the antenna was a post style rather than the wire style, as FM reception might be improved. Speaker connections are of the spring loaded variety and grasp wires securely. USB and SD inputs are nice although I have yet to utilize them. The unit is very attractive with a screen and volume illuminated by a neon blue hue.All in all, the amplifier is a very nice surprise and exceeds my expectations. I can't speak yet to longevity at this time, but hope it is of equal quality. I should mention that the Sunbuck and Pyle brands appear to be related, as the equipment is identical with the exception of branding. I would definitely purchase these products again in the future and recommend them without reservation.

### ⭐⭐⭐⭐ Nice sound
*by A***M on July 22, 2024*

Easy to set up, bass and treble work nice. Anntena not to good but I live in area with bad reception so not its fault. One thing I don't like is it dose auto scan and no way to remove stations that really can't be tunned in so you have to work your way through all the of them to get to the one you want. And has the power to run my speakers. With a SD card the sound is great. Ok update review at 1st didn't think remote worked but it works just not from across the room need to be closer. So now the remote can take you to radio stations without going through one at a time.
