AK45 Amplifier Stereo Receiver Bluetooth 5.0 Power Amp 2 Channel 300W Home Audio Amplifier w/USB/SD Card/BT/Mic Input for Home/Garage/Ceiling/Passive Speaker Theater System

BIG value and performance

Used this for almost a year now, great little amp. The pot has gotten crackly and only pushes power to one speaker but I shuffle the knob back and forth and it works fine again. Overall for the money you can’t beat it.

This little amplifier was really surprising. I have a cheap Pyle HiFi 300w bookshelf speaker system that went bad within 10 uses, the internal amplifier wasn't repairable. I removed the old amp, ran wires directly to the speakers, and then connected them to this amplifier. What a difference, they sound so much better than factory. Don't expect bone rattling bass, but the bass is very decent for what it is, it might sound even better on higher quality speakers. I've been using it for a few months now with no regrets.

FM tuner scans for a station but won't stop to add to a preset as described in the online user manual. Couldn't use the FM which is what I wanted. Returned unit as defective. Bluetooth works great.

I use this for my home theater system and it has plenty of power and great clarity - it has more headroom than I need. I do not use the Bluetooth connectivity often but it is nice to have. It’s also small so it fits anywhere. It does look and feel kinda cheap, and the LEDs are a little bright, but for the price point the functionality can’t be beat.

This AMP is great...It is a step up from the LP-2020A which is a great little box too. But I had a couple of BIGGER dual speakers and the AK45 is perfect for that and includes Microphone jacks and a few other goodies. You can't go wrong with this AK45 AMP for the price. Metal case, all around quality... Even has a remote controller...whew...All I can say is if you want a small quality AMP, BUY THIS ONE!

This little receiver is very good if you need something low power. FM reception is good in the SF bay area with the supplied antenna. The sound quality is pretty good with FM. It's much better than the 1970's Radio Shack receiver it replaced. Sound quality with a USB stick is terrible. Bluetooth sound is very good from my phone and Windows 11 computer. It connects right away. It has plenty of power to drive my old Radio Shack Optimus 1 speakers with no detectible hum or distortion. For a small room or to add music to a garage, this is a good choice for very little money. I definitely like the small footprint. The worst thing is the display which is dark blue. Be sure you remove the protective plastic on it or you will barely be able to see it.

This thing is smaller and lighter than what the pictures lead you to believe. No issues powering a passive woofer box and bookshelf speakers. The Bluetooth works great. One tip, if using the remote to adjust volume, you can make it louder by physically turning the knob on the amp even higher.
