Sunbuck Bluetooth 5.0 Audio Amplifier, 2 Channel Compact Stereo System, 250Wx2, RCA/USB/FM, Speaker Receiver AS-29BU

My 45 year old tuner that was being used in the garage finally gave out. Did some searching and found this unit at a decent price and from the description it sounded like what I needed, and at a good price.Shipped and received on time. Read the very small instructions and fired it up.The Bluetooth connected quickly and sounds pretty good pushing Sirius/XM through an old iPhone 6 for music in the garage. Also worked well when I used the iPhone 11 as the music source.FM capability appears good although I did click a wire to the small antenna to knock down a small "hiss" in the background. Tuning is odd but works well.The remote was a nice surprise and works great for changing volume and mode.It sits out there in the hot garage and runs all day. Can't complain about that as it drives two speakers AND a subwoofer on the Bluetooth stuff from the phone but not on the FM for some reason. It's not a big deal to me but might be for some who will use the FM radio a lot.Overall, a nice surprise at a good price.

I use this for sound in my garage, which is my 3d printer and music practice room. It works pretty well. Electronics is so much better than it was 40 years ago when I bought my first stereo systems, and this is better than anything one could have bought then. It's not got a lot of fancy options, but the ones it has work well. There is no hiss or 60 cycle hum. The first one that was delivered had a whine on bluetooth. But read below for what happened to this.However, the customer service is really excellent. The seller contacted me separately, just to ask if everything was ok. I mentioned the bluetooth whine, and they almost immediately sent me a second unit, and offered to let me keep the first one. I think this is really high quality customer service, and I want to commend them for this.So, I would and will buy this again if I find myself in this market for another of these small amplifiers.

Works and sounds great. Used on my PC with 50-watt speaker.

Bought this unit to connect through bluetooth to my home theater projector and power my speaker system. Had all the features I needed at a reasonable price. Unfortunately the first unit I received started acting up after about 5 minutes of use and quickly stopped producing sound. I was sent a replacement unit which worked well for several days but then also began acting up, first losing one speaker channel and then a few minutes later losing the other channel. I don't feel I was pushing the units very hard as the home theater is relatively small and I am not into high volume levels. My speaker system had been and continues to work well with a 30 year old all-in-one entertainment system so I'm sure the speakers are not the problem. I'd stay away from this Sunbuck unit unless they can improve their quality.

I bought this amplifier as a temporary replacement for my Skar amp (RIP), but I was shocked to see that this tiny guy could power a WHOLE 15 INCH SUBWOOFER!!! Not just that but it can power 2, 8” woofers (not to be confused with a subwoofer) and a 10” subwoofer! If you think that’s all, WRONG! If you connect it to a splitter, I think it could power 3 Orion hccas! The ONLY problem I have, is the noise it makes when searching for a bt device.For all you IDIOTS out there who don’t know that class D amps are the least efficient: If an amp is not efficient, it will make a subtle humming noise. The more efficient an amp is though, the more sound quality you lose. (Not that much though)That being said, this would qualify for a school essay, and I love this amplifier!My YouTube channel is @blueisnotgreen. DONT FORGET THE @

You know when you get a product that exceeds expectations? Doesn't happen very often but I got to tell you something. My old receiver which was absolutely premium in 1973 finally died. For those of you that don't know me, I am really really into music., and I have a really discerning ear. I hear a lot of things especially in music that other people don't necessarily register. My downstairs unit is a '87 JVC component matched system coupled to 2 '87 Bose 501s. Upstairs I did not have a component stereo system but I had the speakers. So I took a chance and bought a receiver off of Amazon for 40 bucks. I expected very little if anything. But the specs were there. Bluetooth, 180 watts per channel, TV input. So I said what the heck and I had a $25 coupon so I ended up paying about 18 bucks for this tiny receiver. I have a pair of Bose 301s and a 1973 pair of 12-in 4-way criterions. These are serious speakers and need to be fed properly to sound right. Well this tiny $40 receiver is absolutely slamming them. I mean my goodness if you have any speakers around your house, I cannot believe the power and quality of this tiny receiver and it hooks up to Bluetooth so I literally have the world's catalog of music through Spotify at my fingertips. It also hooks up to the TV so the sound of movies is getting pumped through a pair of Bose 301s, and is totally immersive. I cannot believe the quality of this receiver, it's a brand I have never heard of, Sunbuck, but holy mackerel what a great piece of equipment. I think I'm going to buy another one for speakers under the bed to go to sleep by and wake up by. The kids absolutely hate it because it practically busts their doors down lol.

Purchased this for my father for use at the river cabin. It didn't exactly what he wanted. It allows you to take audio and project and amplify it to your speakers. It does a great job at that and even the bluetooth seems to be pretty good. It's got a great amplification sound and for the price is a good product. Now of course it is a little bit on the cheap looking side. Some of the inputs look as though they are either crooked or bent. The audio in for the rca cables went out already but the bluetooth function is still viable. So overall it's a good product not very reliable and perhaps I am hoping I just got a bad unit.
