Review on Pyle PLMRMBT5B: Weatherproof Bluetooth Marine Amplifier - 600W Power, 2 Channel Wireless Amp for Stereo Speaker, Waterproof Design, RCA/AUX/MP3 Input by Dustin Ramsey

Making a portable Bluetooth speaker system for car dealerships and the like. This block worked several times. In the end, Bluetooth had connection problems. Nothing works anymore. power supplies changed. Nothing yet. Since I already have a solid control panel drilled into the case I am ordering another one of the same type. If this doesn't last long, I'll have to give up the whole project.
