Review on Pyle PT506BT.5 Professional Powered Amplifier & Bluetooth Receiver: 600 Watt Stereo Audio System with FM Radio, Mic Inputs, MP3/USB/SD/AUX Playback & LCD Display by Tim Reimann

I am using it outside in a large gazebo. I have it covered but leave it year round. I know the weather will ruin it, the last one lasted 3 years and worked great too. This is a slightly modified model. The bluetooth connects better than the old one and there is now a bluetooth antenna that extends the distance to your device. For the money, this is a great little device that packs some serious volume. Connected 4 speakers, the sound is excellent. I recommend buying this device.
