AK45 Stereo Audio Amplifier,300W Home 2 Channel Wireless Bluetooth 5.0 Power Amplifier System, Home Amplifiers FM Radio, USB, SD Card, with Remote Control Home Theater Audio Stereo System

Although this amplifier is basic, it sounds great, and meets all my requirements. It powers my media center JLB bookshelf speakers as loud as I want, with clarity and full fidelity. The price was right. The radio works great too. The remote handles the volume and frequencies, Bluetooth, mode, and mute. I found coordinating the volume knob with the remote gives a fuller range of volumes. The amp is small, so I must wear my reading glasses to read the labels for the many buttons and knobs to operate, but setting up is easy. It may not be good enough for those who want the best, but it is an excellent buy for my money. I do not regret my trade off.

I must say, I was skeptical about the quality of this item after viewing the listed price and it did not bear any markings of a brand that I was familiar with. Nonetheless I ignored my reservations and decided to follow through with the gamble. What a payoff! The benefit greatly outweighed the risk in this instance.Firstly, I received my order on time, properly packaged, in flawless condition and accurately matching its online description. After unpacking, this amplifier was test driven with a pair of AudioSource LS300 speakers and it did not disappoint. Sound quality was clean and crisp, with all its capable frequencies pleasantly audible. Don’t get me wrong, this unit does not rock the house with low frequencies and deafening SPLs but does well filling a small space with amazing quality sound.Despite its small footprint, it hosts the following features: FM receiver, Bluetooth, AUX input, USB and SD card. Not only is it easy to cycle through these features but they all work as intended without any hiccups. This is especially applicable to the FM receiver which delivers clear reception from all frequencies tested.It has been more than four months since acquiring and using this amplifier and I haven’t had any problems or regrets. I would definitely recommend this to anyone interested in acquiring a well built, inexpensive, easily operable and great sounding amplifier.“Well done!” to the manufacturer and to the online retailer for making this product available to us…

Very impressed so far with this little one. I needed a new receiver/amplifier for my outdoor speakers as my much older (much bigger full size) pioneer receiver finally saw its last days. I only needed a 2 channel setup as im running those speakers in stereo mode and so far this thing is great! Plenty of power, and in fact i have 4 speakers in total outside, 2 left and 2 right, with probably 75 ft. of speaker wire to the furthest one out. It has plenty of power to push the signal and then some. I have it set to maybe 2 on the volume knob and its definitely loud enough. Love being able to stream blu tooth to it, and while it does have connection issues the further away you are (i experienced fluctuations at 20 feet) I have a microsoft surface tablet sitting near it, and no issues of course at that distance. So probably the only reason i dont give it 5 stars is that somewhat short connectivity distance for blutooth. Otherwise definitely worth the cheap price, and far out exceeds my expectations for such a cheap unit. If it breaks early on ill update my review, but so far so good!

The price point is exceptional for the quality received. I've had receivers since the 70s, and this is an impressive little unit. I appreciate the compact size, and it's great having the little remote. I have a fairly cheap phone, and the connectivity of the Bluetooth is solid; zero issues. I am using 14 gage speaker wire with good performance even at higher volume. The power cord is a bit shorter than I would prefer.

I bought it to replace an existing stereo amp. The sound quality is great. The price is awesome. But 2 things made me take a star. However, these issues may cause a much lower rating if it was in use in different settings. The 3-star rating is only for my current situation.First, the Bluetooth range is quite short. The unit wouldn't connect well at first. So I moved the Bluetooth adapter to the computer that was closer to the unit. This time, it connected fine. But the sound would stutter. So I moved the card to the computer that was closest to the unit. The Bluetooth connected easily and the sound quality was great without any stutter. In fact, it was better than when I used the previous amp. However, the old unit used to be able to connect to the computer that was farthest away without any issues. Perhaps the Bluetooth antenna makes the difference. The old unit had a Bluetooth antenna whereas this unit didn't. The closest unit is about 15 ft away. 2nd closest unit is about 25 ft away. The farthest one is about 35 ft away. There isn't any obstruction between the computers and the unit. Perhaps this unit's Bluetooth isn't 5.0. The old unit (Bluetooth version 2.0) was able to connect to the same adapter when it was plugged into the farthest unit. I'm keeping it in spite of the problem because it's functioning fine and for $35, it's good enough.The second problem is remote control. No, battery isn't the problem. The power button works fine. But the volume control doesn't work at all and the mode button works intermittently.Again, this isn't a problem for me because I'm using this unit to play music all day in a retail business setting. So I don't need to manipulate volume or change modes. I just turn it on in the morning and turn it off at night. So I'm keeping it as is. However, this would pose a big problem in a lot of different settings. So beware. I'd have returned the unit if I were to use it for personal use. The 3-star rating was given for my current situation.Update: As of March of 2025, the unit is caput. Initially, I got plenty of distortion and thought it might be the wire or the speakers themselves. Did the trouble shooting and turns out it was this amp. While waiting for the new amp to arrive, it gave out completely one channel at a time. At this time, it is completely dead. That was 15 month lifespan for 30 some dollars. I guess that's not terrible considering the price.

So far Excellent! Amazing sound and function in such a small package. I replaced a Pioneer tuner/amp that was 4 times bigger and this tuner/amp has just as good sound. Hoping it holds up.
