Review on ⚓️ BOSS Audio MCKGB350W.6 Marine Gauge Receiver and Speaker Package - Weatherproof, IPX6, Bluetooth, USB/MP3, AM/FM, NOAA Weather Band Tuner, 6.5 Inch Speakers, CD-Free by Lance Jenkins

My only complaint is that it's not loud enough when my boat is moving (17ft open bow with a 3 liter Mercruiser) but it is loud when paused but volume is muted. before maximum volume. Also, condensation sometimes appears on the screen, but this does not affect the functionality. Bluetooth works great and is responsive, has subwoofer connections and great EQ settings. Edit: After adding a subwoofer to take the bass out of the 6.5 speakers, it got significantly louder and the volume reaches a much higher level. Haven't tried to maximize it yet but I'm still very happy with this product.
