Review on 🔌 Xtenzi 12V RCA AUX Adapter: Wireless Dongle for Optimized Car, Boat, and RV Stereo Device Connectivity by Brandon Rogers

It was very easy to install on my boat by connecting 12V power and RCA cables to my amp. Turned on well, but after pairing with any Bluetooth device (I've tried LOTS) there's a loud buzzing coming out of the speakers. Even if you play music, you can still hear it. I thought maybe I just got a bad one so I asked for a replacement and still got the same result. I sent both back and bought another one and it works great.
