    • Good and cheap
Style: 4.1 Channel
I heard two sets of 6 1/2 component set sitting around the house for a car that was total so I had a wild hair of building this around town out of those component set and they worked out not perfectly but OK but this little amp pushes them very well. The remote is very small so it is easy to lose, but it is very user-friendly. Volume only goes up to 30 or so, but it is loud enough. ... show more

    • Great product for the money
Style: 4.1 Channel
This is a really good little amplifier that I used for four powerful outdoor speakers at my pool. It’s installed in my outdoor kitchen inside the cabinet. The Bluetooth still works great has a more than reasonable range in the output is surprisingly good. This is it great product for the money.

    • Amazing sound at the price point if you can take the "connected" indicator beep
Style: 4.1 Channel
Needed something cheap to power the TV surround since we are selling our house. Wow, I did not expect this to sound as good as it does. And the mixed reviews on the subwoofer might be because they are using passive subs. The bass is clean and deep with lots of room to turn up the volume. True its not stereo, but thats okay at this price point. The ability to control the volume of the a/b and the c/d seperately is what led me to keep it over another common receiver in this price rage where my surround speakers were louder than my mains due to sensitivity, and the bass sounded much better on this too, bonus. The lost star is for the annoying connection note that you cannot mute and can be loud if you have the units volume up (very loud), BT with the LG TV was very easy to setup and convenient. The build quality was better than expected and there are a wide range of input options making this a versatile little amp at its price point ... show more

    • Unbelievable Capabilities. Amazing!
Style: 4.1 Channel
Exceeded every expectation. MP3, Bluetooth, a remote, 2 speaker sets and subwoofer? I tried every one. Slipped a SD disc in FYI, it goes in bottom side up. Awesome. Pair phone and did bluetooth. Awesome. Cable connected to computer monitor for sound out. Awesome. I am getting ready to try the subwoofer. It even has preset equalizer settings via the remote. Skipped around the SD card using the remote. Way beyond in value from a product priced in the $40's. Wow. ... show more

    • This is perfect!
Style: 4.1 Channel
I had this as a replacement idea because another one (pyle marine BT one) ended up not working at all. This one is great! Good bass and the Bluetooth is really cool! Ultimately I realized I wanted to add a mixer for a few karaoke microphones and added a separate Bluetooth transmitter in the mix too. So now I have 3 microphones and a tablet input through the mixer to the transmitter, received to this unit which pushes 2 channel stereo to a pair of great 5way 6x9s and a 12 inch sub. It fills the party bus perfectly. No window shaking, no cracking or hissing. ... show more
