Bluetooth Amplifier AK55-2 Channel Speaker Amplifier Car Amp HiFi for Speakers FM Radio, Karaoke, w/USB/2 MIC/SD/MMC/FM Inputs & Remote Control, for Home Theater & Bookshelf Speakers

The Amplifier is perfect for the garage.

The media could not be loaded. When powered on it seems to be stuck in a no station FM mode nothing else works except the microphone section even when this works it has a crackling soundBluetooth don't work either

For what I wanted - a cheap amplifier with blue tooth connectivity - it seems fine. No idea what the true power output is, but it's fine for my use. It is perfectly adequate for use to drive a couple of OK speakers. Why only 3 stars? The radio performance is dire. It might be something wrong with my particular set. I have a few other similar amps and they have radios that can receive radio. This one seems incapable of picking up any channels either with the supplied wire aerial or with a better rod aerial. Not a problem for me but it might be for others.

very good for the price

The one interesting thing about this amplifier is that there is zero information about how much power it has. The build quality is ok, if a little on the cheap side, and the unit has little weight to it. It feels as though most of the inside is empty.Speakers connectivity is limited to just wired only, which is somewhat limiting in this day and age, but there's plenty of inputs.If I'm honest, I would say this is best suited for testing devices to see if they're outputting a signal through the amp to whatever speakers you have connected. You could have it sitting there with a pair of speakers connected up, together with various input cables, and the test devices as and when required. I have it setup in my office, connected to a pair of Edifier desktop speakers, exactly for this.It does come supplied with a cheapish remote control and an aerial. Sadly the aerial doesn't do anything for me, but this is down to the area I live in.As well as for testing, this would also be handy for kids as well.I hope you found this review & photos interesting, informative, and useful. Thanks for reading.

I needed an amplifier at short notice to use while repairing some speakers. I was able to hook up the amp easily using some old wire (no plugs needed) and I was able to play test tones and music right from my phone via bluetooth. There's a load of functionality in this little box - it seems like it would be a great way to get more use out of a set of old speakers.

I got this amplifier for use in my workshop, my previous radio has been outdated by DAB+ being the favoured choice for radio stations. I simply plug a DAB+ radio into the AUX input of this amplifier.This little amplifier comes complete with remote control, FM aerial, power lead and very poor instructions, the particular item I received has had a good whack on the back of it, denting the metal case where the power input is and also breaking the clips that hold the front panel, this doesn't bother me at all but for some people, this item would have been a return back to Amazon.I connected up my old speakers and started setting this amp up.Firstly the supplied instructions are very poor and trying to follow them is pretty awful, I managed to set up a Bluetooth connection pretty quickly and easily, but the instructions don't state what name to look for in the Bluetooth list on your phone, simply printing the name in the instruction swould have made connecting to Bluetooth so much easier.The FM radio is next door to useless, it's hard to tune and the tiny buttons on the display seem to work intermittently, I managed to get the tuner to scan for stations but they all sounded very hissy, even local stations, maybe using a better aerial instead of the supplied wire would help. Again instructions are less than helpful here.Next up I tried the USB input, I plugged in a music-loaded USB drive, and the music played quickly but navigation is a nightmare, you can use the remote to enter the track you want to play but if you have a stick with 100s of tracks on this is virtually impossible, one saving grace is there is a random button on the remote. You can, again use the little button below the display for track forward/back and MP3 volume.There is plenty of inputs on the little amp, these are RCA AUX 1 and 2 plus Coax and Toslink optical on the rear panel and on the front panel there are 3.5mm AUX, USB socket and two microphone inputs, the microphone ins feature volume level, echo and delay adjustments, so this amp can be used as a PA too or maybe Karaoke. There is also a 12v DC input on the back for use in a vehicle a 240v AC input and a coax FM aerial connection. There is no lead supplied for the 12v dc connection. Speaker connections are simple spring-loaded connections commonly found in cheaper audio units.Sound quality is OK for basic needs, there are bass/treble controls and pre-set EQ settings, I note with interest there is no mention of the RMS output of this amp in any of the specs, the weight gives of this amp gives it away that it is a single chip amp commonly found in cheaper car radios and maybe 5 watts RMS per channel tops, fine for my workshop, it is loud enough using an old pair of Goodmans 2 way speakers that have 4ohm impedance, it is by no means HiFi.The remote is basic but functional, the buttons feel tactile and positive.I can't help but feel this amplifier could be improved, the display is very poor and lacks information especially when connecting Bluetooth devices, this could be made so much easier with a simple flashing connection LED. The build quality also needs to be improved, the buttons under the display feel very cheap and sometimes just don't respond to being pressed at all. The power switch also appears to be upside down.It's OK for a workshop or cheapo PA.

Hosted a karaoke night with friends, and this amp stole the show! The mic inputs worked perfectly, and the sound was crystal clear. Everyone had a blast—definitely buying another for my cousin!
