AK45 Stereo Audio Amplifier 300W Bluetooth 5.1

Great functionality for the price. Easy setup and Bluetooth connectivity works very well. Sounds just fine through a stereo setup, easy to adjust bass / treble with knobs on amp. Comes with a remote although I will likely never need that feature.

This is one of few items I sought out to post review. I’m old school, graduated high school in 80’s and been missing the sound quality in music that could get from cranking the old 200 A speakers that take up a space in the room! This device helped me get that back. And for a price that I feel more than fair. I brought out speakers that had not been used in 20 yrs and hooked this up, very old school, simple, and again enjoyed music the way is meant to be heard! Bluetooth is stable for my use (larger workshop and small yard area). And also love fact that is small enough that can easily disconnect from speakers in workshop area carry it out and connect to speakers in outside work area. Quite possibly one of my very favorite purchases for myself in very many years!!

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!

This is something that I found in a shop garage, and I liked it, so I got one for myself.Pros: It is small but packs a punch with the right speakers.The remote is nice for putting it someplace high and keeping it out of the way.It looks like it is durable. I use it in my wood shop, and it sounds great even over the saws and shop vac running.Bluetooth connection is good. I have my phone in my pocket most of the time while walking around the garage, and it stays connected. I have walked out of the garage to the other side, which normally would kick off other things, and it still works.FM radio works great. Ran the wire outside, and I am getting all my local stations I want to listen to.Cons: Nothing so far. I am happy with it.

If I could give less than one star I would. Spend the right money and buy a quality product from a reputable seller, not this. I bought this after being influenced by TT. It seemed like a great option and the seller made it sound like it was backed by good customer service.Well, the unit lasted a couple weeks before having BT connection problems, audio volume control problems, and now the radio won't even work, it just buzzes.I figured oh at least this comes with a warranty and customer service 24/7....WRONG!The email address they provide for customer service takes you to a dead email address so that's cool. And then if you try to reach out to them on here for help, they will respond to you maybe after a few days until they ultimately ghost you after capturing your address saying they will send a replacement product....but never do. So horrible customer service there as well. A month and a half later and still nothing from them.I cannot stress enough that you buy something else from some other seller!!!! Do not buy from these people.-little to no customer service even though they say 24 hrs on the item page-product has failures reported across the boardSave your time and money and buy somewhere else.

Very nice with tons of possibilities. My immediate use is for the rear speakers in my surround sound system. I’m switching over from the 3 in the front, 2 echo speakers in the back with a subwoofer to live speakers in the rear. I’d always operated the rear speakers in I think they call it 5.1 mode where the rear speakers are simply a delay of the front speakers. When I’d bought them, there was no 7.1 mode but the speakers were a good quality and I’d always thought that I’d wasted a little money buying such a quality speaker for that purpose. A couple of years ago I purchased a new receiver and didn’t pay attention to it’s long list of applications. I later realized it supported 7.1 sound so with a separate amplifier, they could be fully integrated into the surround sound system. This amp did all that and more. I’m not currently using the Bluetooth functionality but plan to set that up as well in the near future. Don’t let the size of the amplifier throw you off. It’s very powerful and puts out some real power for clear and crisp sound. The size makes it possible to put the amplifier close to the reciever without even knowing it’s there. I have been able to connect to it pretty easily from a 2 room away range within my typically sized ranch style home.

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.

Wasn't sure if this little amp could power a set of 60 watt speakers I've been wanting to hook up in the garage for a long time. Well, it does the job and the big sound I'm getting now while working on household projects is awesome. I highly recommend this little beast.
