Crystal clear 2.1 sound

I'm glad I chose this amp, I use it with refurbished speakers from my previous 5.1 sound system (although it's 2.1 but I managed to get 4 out of 5 speakers plus a subwoofer to connect) sounds amazingly crystal clear. The Bluetooth connection is excellent. It took me a while to figure out what the best subwoofer frequency setting is, but I found the perfect one for me.

Pros
  • New
Cons
  • Some bugs

Great little amp! good for amplifier

this thing can give some juice! I powered an inexpensive 12" subwoofer I bought at Walmart with this little amp and it did the job perfectly. become loud! I tested it with some tweeters and 5" midrange drivers and it worked great. The clarity is unreal, no static or annoying hum coming out of the amp when I paused the music, even with the volume cranked all the way up. This is one of those purchases where you can't believe the value compared to the actual price of the product. TO BUY! You can't

Pros
  • receiver and amplifier
Cons
  • some problems
