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!

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.

I took a chance and this device performs very well for a small package. It's about half the size of an average cable box and very light in weight. But the sound and range it has is very satisfying. I use it as my sound system for my big screen TV and I play music per bluetooth. I'm very pleased.

I bought this for a garage stereo, so clarity and sound only have to be acceptable. I'm using Polk TSI100 speakers. The AK45 seems to be two different components that are semi-integrated. Amp and tuner/BT/line-in really seem to be discreet units with some integration.Summary (so you don't have to scroll): It is fine for the price. Not very powerful in its ability to put out a full spectrum of sound at a medium to high volume. I think 300w max and maybe even 50w RMS is 'optimistic'. The controls have their nuances.Pros:= Size is small enough to fit on top of the speaker.= Inexpensive.= FM reception is above average.= Bluetooth sound frequency range is pretty good.Cons:= I have a Fosi 2.1 channel bluetooth amp of the same wattage and it blows this unit away in the power and sound department. The AK45 has some bass, but not much. The highs end up being way too high if you turn it up enough to have even modest bass response.= It seems like there are two control units operating in the same box. It has two volumes. One controlled by the knob and one controlled by the remote that is a sub volume of the knob. The knob is not powered by a motor and does not rotate with the remote input. Careful, because if you switch between modes, the volume kinda 'resets'. The change in volume can be significant. With secondary volume turned up all the way, the volume can get very loud at only 1/3rd.= The FM sound frequency range is limited. Every station sounds like you are listening on some small transistor radio from the 1970s.Other:= Light weight. I suspect this is due to the design and omission of heat sinks.= The power switch on the front is the master power. Using the remote is almost like a standby 'off', but the lighted power knob stays on.= The amp part seems to be controlled in many ways separate from the music processing part.
