Daakro 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

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…

Awesome stereo. Bluetooth hooks up w out any issue. Decent sound and best part is that it is so compact!

I didn't buy this as stand alone amplifier. I have a Pheanoo 15 soundbar for my 75" Samsung TV. The sound bar came along with a 4" ported subwoofer (box shown in photo). After 2 years of use the subwoofer foam surround started to detach from the cone and sounded horrible. So I am innovative so this is what I did. I cut the cloth covering the speaker then pulled the blown 4" subwoofer. I was surprised it was rated for 4 ohms instead of the usual 8 ohms for home use. The blown speaker was rated for 40 watts and I assumed it was 40 watts RMS. Now I could have bought a 4" sub rated for 4 ohms and just hooked it up and been done with it. But I had a pair of 6.5 inch component speakers from an old car installation that was rated for 30 watts RMS 300 watt Max and obviously 4 ohms. So what I did was cut the ported box for the 6.5 inch to fit into. Problem solved I had the bass back and worked just a tiny bit better than the 4" factory subwoofer. But gears started turning in my brain and said if one speaker is just a little better and I have a second speaker from the pair two speakers would be better. So I started searching for little amps on amazon and to my surprised I came across this little Daakro AK45 and it was rated for the almost the exact rating as my 6.5" JVC component speakers, 40 watts RMS and 300 watt max. Perfect match and for the price i couldn't beat it so I bought it! To make it work for my application I cut the 2 wires running to the subwoofer box and spliced in 2 male RCA connectors from my old junk wire drawer. The wires I cut were clearly labelled + and - so I stripped the cut RCA connections and wired the positive wire to both positive wires for the RCAs and the same for the negative. Put it on Aux and turned on the TV and soundbar and the soundbar fed the input through the RCA connections to the amp and the amp fed that signal to the replacement speakers. It worked but this is where it got tricky with trial and error. I was getting signal after matching the input level by ear ( I couldn't find my Oscilloscope) when I shut off the TV and the soundbar shut off I would get a buzzing sound though the 2 speakers the amp fed. Now when the TV and sound bar is on and muted there is zero distortion or buzzing noise. It wasn't super loud but bothersome none the less. So I started turning the power switch off on the amp at night when not in use. But when I turned it back on and the TV and soundbar kicked on it would distort out bad and the input level didn't match up like I had it set, it was way to high. Now i fought this for day until I realized there is actually 2 different input levels for this amp. There is the analog dial which I was adjusting and there is a remote that came with it. When u turn it up and down with the remote it ranges from 0-30 digitally, the analog dial doesn't change, there is a digital level. Regardless of what you set the digital level to when you power the amp off with the power switch then turn it back on the digital input gets reset to the maximum of 30! This explains why I could never maintain proper input level matching! Now I understand that using spliced RCA connectors from a high level input source without a high to low input adapter isn't ideal, that could very well be why I'm getting the buzzing sound when the TV gets turned off. But when I turn the digital input to the middle which is 15 and then set the analog input dial I get way better sound with more bass and no distortion. I have a high to low input adapter sitting in my wife's old vehicle from an old car audio installation so I'm gonna rob that to see if it resolves the distortion I get when TV is turned off. And if it is resolved I will update this review but doubt it will be. It could be just the type of sound bar I have who knows but i wish this amp didn't have 2 separate input levels of digital and analog and since it does I wish they had some kind of constant wire to retain memory of where the digital input level was set when powered off manually with the switch. But my review is for the money your not gonna find much better for the money and for the abilities such as radio and bluetooth and Aux. But if your planning on buying this and powering any kind of real 3 way home entertainment speaker ya know a tweeter a mid level component and a subwoofer this product isn't what your looking for. 40 watts RMS isn't even as powerful as most car radio head units that are rated for 50 watts per channel. Yes it will give you sound but it will not move and real home 8 ohm subwoofer in a 3 way or 4 way speaker configuration. I'm very surprised its handles 4 ohm speakers, most home audio is 8 ohm or higher. For those who don't understand what ohms are they are basically the resistance for the amplifier encounters when converting the input signal to usable power. The lower the ohm of the speaker the lower resistance the amp encounters to produce the power to the speakers. A typical 8 ohm home speaker will encounter double the resistance to get power from this amplifier compared to a 4 ohm speaker. If you have 8 ohm speakers of any real power handling capacity I would strongly discourage this product. Don't focus on the 300 watt Max Rating, focus on 40 watts RMS rating but I assume that would be the RMS for a 4 ohm speaker and not an 8 ohm speaker or higher. Now there is a way to change the ohm resistance that the amp encounters when wiring speakers that is typically for a dual voice coil subwoofer or when wiring speakers in series which this product wouldn't be for an application such as that. P.S. If using this for the application I did, my soundbar had built in low pass crossover to block out the high frequencies from reaching the speaker but still turn the treble all the way down. Now if I wanted to listen to the radio or use the bluetooth or SD cards I can get high frequencies from my speakers since they are component speakers but my primary use is for my TV soundbar. If I listen to music its thru apps like Spotify or Pandora

Very good amplifier. I use it for Karaoke and it works out great. Also great for Bluetooth my pandora song list.

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.

Update: at first blush I told myself I was going to be happy powering large bookshelf speakers. Today I felt adventurous and connected this little box to two big cabinets from 1986 featuring 15" woofers. After driving these suckers for two hours, the little box didn't even get warm. Way impressed I am. Previously: Enough power for my large bookshelf speakers. This is my first mini-receiver. Surprised by the good, clean quality audio, and I like having the Bluetooth function. Make sure to get + - wires correct between this box and your speakers. Incorrect, thus out-of-phase speakers will sound noticeably inferior to in-phase. Using the big knob on the amp and a volume level on the remote, you get the joys of gain staging. A little experimenting quickly gets you to a sweet spot for both potentiometers.

Set it up on 4/29/26. Tied it into my speakers. Bluetooth and fm radio work. Stereo operates as designed. Best $30 bucks I’ve ever spend.

If you're buying this, you're probably just looking for an affordable compact replacement. The unit is smaller than I was expecting which works out well. The sound quality is a little less than my prior receiver especially in the bass range (I'm using the same speakers and wires). Rock music sounds great. The instructions that come with it are a joke and don't make sense half the time. Bluetooth does work well and the range is as advertised. The USB port does not charge my phone even enough for slow charging so it's purely for flash drives. Overall it gets the job done but it's nothing special.

Excelente producto
