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

Excellent price for a basic unit that performs very well. Very good power to produce high quality sound via Bluetooth thru 2 quality speakers. FM tuner also responds well and unit includes additional input options.

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.

My audio Setup: I have an echo dot on the back patio and 2 bare outdoor speaker (non powered) with wires run back into the house.This device is on a shelf inside, about 15 feet from my patio echo dot, it automatically connects to the dot if the receiver is on, so now if im outside I can tell Alexa what music to play or skip song, change the volume etc and all the commands work great.Pros:Works great with my Alexa. Volume is more than I can handle honestly so 5 stars for that.It's a small device so fits on the shelf easy, has a nice look.I like the bass and treble options.FM radioIve not tried the SD card or the USB optionsCons:The bluetooth range is pretty limited. I'd say 15 feet if there's a wall is the MAX.The FM antenna is not very long... I feel like I get some static on the weaker channels.NO FM Radio TUNER, and you can't set FM presets as far as I can tell... pretty much it does a full scan the first time you run it, saves EVERY channel as a preset and if you want to change channels you just press the >> button until you get to the channel... a little tedious but whatever, I mostly use Alexa.But overall for the price this thing does exactly what I want it to do with really minimal set up and so im pretty happy happy with it.

Great little amp for our basement speaker set up with lots of options. Kids love it, because it;s easy to find and they BT with phones.

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.

Love this stereo!Easy to setup! Its bright sound and power is just amazing. It’s small size makes it easy to setup and it’s Bluetooth is a great bonus.

Purchased this for my garage and speakers seperately. Everything works and sounds well. I play CDs through a DVD player hooked to it.Bluetooth range could be a little better compared to other things I've used but this gets the job done.
