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

DO NOT buy this item! I decided to ignore the negative reviews and order this product. After installation, the power indicator lights up, but there is no sound from the speakers. I tested the speakers with a different amp and they worked fine. I removed the rubber cap and adjusted the volume screw but still no luck. Unfortunately, the sellers of this item know this is junk and are giving you a limited return window. Take my advice and spend a little more to get an item from a trusted seller that really works.
