Its compact, round gauge profile mounts into a standard gauge cutout using the included metal bracket, hexagon mounting studs, and M4 secure nuts, making it a practical option where panel space is limited. The receiver streams audio wirelessly via Bluetooth from a smartphone or MP3 player, giving direct control over apps like Spotify and Pandora, and also accepts a 3.5mm auxiliary input for wired devices. A USB port supports both playback from connected audio files and device charging, so a phone can stay powered while streaming music.\u003c\/p\u003e\u003cp\u003eWeatherproofing is built into the unit rather than added on, with front panel UV coating and a conformal-coated PC board that carry an IPX6 rating against splashing water, making the MGR350B suitable for open boats and other exposed helm locations. It includes a built-in 4-channel amplifier rated at 240 watts total output (60 watts x 4 channels), along with front, rear, and subwoofer pre-amp RCA outputs for connecting external speakers or a subwoofer. This is a receiver only, with no CD or DVD player, keeping the unit compact and further reducing points of water or dust intrusion. The finish is black to match typical marine dash and gauge cluster styling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e BOSS Audio Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e MGR350B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnectivity:\u003c\/strong\u003e Bluetooth, USB, 3.5mm Auxiliary Input\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Devices:\u003c\/strong\u003e Amplifier, Smartphone, Speaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Channels:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Power:\u003c\/strong\u003e 240 Watts total (60 Watts x 4 channels)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Features:\u003c\/strong\u003e Built-In Bluetooth, USB Charging, Weatherproof, No CD\/DVD Player\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance Rating:\u003c\/strong\u003e IPX6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e RCA (front, rear, and subwoofer pre-amp outputs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 3.86 inches D x 3.54 inches W x 3.54 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e Metal bracket, hexagon mounting studs, M4 secure nuts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 791489122979\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes the BOSS Audio MGR350B play music from a phone wirelessly?\u003c\/strong\u003e Yes, the MGR350B streams audio over Bluetooth from a smartphone or MP3 player, giving direct control over apps such as Spotify and Pandora.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the MGR350B waterproof enough for an open boat?\u003c\/strong\u003e The MGR350B carries an IPX6 rating from its front panel UV coating and conformal-coated PC board, which protects it against splashing water on an open helm.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the MGR350B receiver?\u003c\/strong\u003e The MGR350B measures 3.86 inches deep by 3.54 inches wide by 3.54 inches high, sized to fit a standard round gauge cutout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the MGR350B weigh?\u003c\/strong\u003e The MGR350B weighs 2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the MGR350B have a CD or DVD player?\u003c\/strong\u003e No, the MGR350B is a gauge-style receiver only and does not include a CD or DVD player.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many channels and how much power does the MGR350B put out?\u003c\/strong\u003e The MGR350B has a built-in 4-channel amplifier rated at 240 watts total output, or 60 watts per channel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the MGR350B charge a phone through USB?\u003c\/strong\u003e Yes, the USB port on the MGR350B supports both audio playback and charging a connected device.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat mounting hardware comes with the MGR350B?\u003c\/strong\u003e The MGR350B ships with a metal mounting bracket, hexagon mounting studs, and M4 secure nuts for installation into a gauge cutout.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I connect external speakers or a subwoofer to the MGR350B?\u003c\/strong\u003e Yes, the MGR350B provides front, rear, and subwoofer RCA pre-amp outputs for connecting external speakers or a powered subwoofer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the BOSS Audio MGR350B?\u003c\/strong\u003e The MGR350B has a black finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a wired audio input option on the MGR350B besides Bluetooth?\u003c\/strong\u003e Yes, the MGR350B includes a 3.5mm auxiliary input for connecting smartphones or MP3 players by cable in addition to Bluetooth streaming.\u003c\/p\u003e","brand":"Boss Audio","offers":[{"title":"Default Title","offer_id":49026450522331,"sku":"BOS-MGR350B","price":148.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/hck7gpbjnm02lc8huics.png?v=1785026570","url":"https:\/\/www.goodvibesmarina.com\/products\/boss-audio-systems-mgr350b-marine-gauge-style-bluetooth-stereo-receiver-with-built-in-4-channel-amplifier","provider":"Good Vibes Marina","version":"1.0","type":"link"}
