Review on 🔊 Pyle PLMRLEWB47BB: High-Powered 4 inch Waterproof Marine Grade Tower Speaker System with 300 Watts, Bluetooth Wireless Streaming, and Pair Option by John Pineda

The wiring diagram is not included and is not easy. Each speaker requires two positive and two negative wires, and just for fun, their wires are different gauges, and one of the positive wires is blue. So you need to run four positive and four negative wires. I had to install a separate line and ground bus. I had to install a breaker because I didn't have a breaker. Connected directly to the Bluetooth and then even the speakers didn't work. Called support and was told I could pay to have it sent to them and told them I was done with that.
