Awesome radio for your adventures

The Boss MGR350B digital media receiver packs a lot of features into a compact design. Crank up some AM/FM radio, or plug a compatible device into the rear USB or AUX inputs.

The package also includes a panel-mount USB port so you can plug in a thumb drive or music player.

And when you purchase the package, you can save $50 on a VIP dash that's custom-designed to fit select Club Car or E-Z-Go golf carts and hold your gauge-style radio.

Note: This digital media receiver will not play CDs.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

Marine Gauge-Style Receiver
Marine Two-Way Speakers

Marine Gauge-Style Receiver

IPX6 Certified: The Boss Marine gauge-style receiver has been engineered and tested for use in the harsh marine environment. The marine digital media receiver features UV coating and PC board with conformal coating to prevent fading and protect against corrosion. It also features IPX6 waterproof certification, so it can hold up in the marine environment and withstand powerful splashes of water out on the ocean or lake. During testing, water is projected at all angles through a 12.5mm nozzle at a flow rate of 100 liters/min at a pressure of 100 kN/m2 for 3 minutes from a distance of 3 meters.

Note: This unit should not be submerged in water.

Gauge-Style Mount: The Boss Marine digital media receiver can fit in a boat's 3" gauge-style opening. If your boat does not already have a gauge-style opening, the marine digital media receiver requires a round 3" cutout in the bulkhead for inserting the chassis. The integrated protective gasket, supplied U-bracket, and included hardware secure the unit in place against the mounting surface. Receiver dimensions are as follows -

  • Chassis & Cutout: 3" (diameter) x 4.3125" (depth)
  • Front-Panel: 3.625" (diameter) x 0.8125" (depth)
Note: The receiver is round and does not include a mounting sleeve or ISO-mount screw holes to accommodate standard automotive installation.

Crutchfield Wiring Kit: The included Crutchfield CK12 wiring kit comes with a 12AWG power (17') and ground (6') wire; along with fuses, terminals, grommets, loom, and ties. RCA cables and remote turn-on lead not included and not needed unless you are also installing an aftermarket amplifier.

Bluetooth Audio Streaming: Thanks to built-in Bluetooth 3.0, you can wirelessly stream stored music and music apps from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, or other Bluetooth source device to the Boss Marine gauge-style receiver. The unit offers Play/Pause & Previous/Next Track control (there is no song/artist info display).

Note: This unit does not offer support for Bluetooth hands-free phone communication.

USB-A Port: The Boss Marine gauge-style receiver is fitted with a rear-panel USB-A port attached to the rear-chassis via a 7" cable. The USB-A port allows you to plug in your USB mass storage class device, like a USB thumbdrive or portable digital audio player (up to 32GB) for playback of MP3/WMA music files (up to 65,000 songs). Your USB MSC device must be formatted in FAT 32. The unit offers Play/Pause & Previous/Next Track control (there is no song/artist info display). If your USB MSC device can be charged via USB, the unit's USB (5V/1A) port will charge your device while connected.

Note: The unit's USB port does not support Apple iPod/iPod/iPad, Android smartphones/tablets, HDDs, or USB hubs.

Flush-Mount USB Extension Port: Aquatic AV's AQ-USB-1 flush-mount USB extension cable connects to the rear-panel USB port on the back of the receiver, and provides a convenient connection for your USB source device. The female USB (type-A) port of the USB extension cable features a flush mountable design. Simply drill a 3/4" hole at the desired mounting location, feed the USB extension cable through the hole and insert the female USB connector into the hole, and then use the included threaded locking collar to secure the flush-mount USB connector in the cutout.

  • Overall Dimension: 1.1875" (diameter) x 1.75" (depth)
  • Cutout Dimension: 0.75" (diameter) x 1.3125" (depth)
  • Cable Length: 5'

Aux Input: The Boss Marine gauge-style receiver is equipped with a rear-panel stereo RCA Aux input attached to rear-chassis via a 7" cable. The stereo RCA aux input allows you to connect an external audio device with a stereo RCA output. If you have a source device that has a 3.5mm output, then you will need a stereo RCA-to-minijack adapter (sold separately).

AM/FM + Weather Band Tuner: The Boss Marine gauge-style receiver features a built-in AM/FM tuner with RDS, plus a 7-channel NOAA weather band tuner. You can store up to 12 FM and 6 AM preset stations. You can also select between US or European tuning. The Radio Data System (RDS) feature displays radio broadcast information, such as artist & track information when listening to compatible AM/FM stations.

Note: A 41" marine dipole antenna is included.

MOSFET Amplifier: The Boss Marine gauge-style receiver is equipped with a MOSFET amplifier rated at 20W (RMS) x 4 channel / 60W (Peak) x 4 channel.

2V/4Ch Pre-Outs + Sub Control: The marine digital media receiver is fitted with a 2-volt front pre-out and a 2-volt rear/sub pre-out. When set to sub pre-out, you can adjust the sub's low-pass crossover (80/120/160Hz) and sub level control (0-12).

EQ: The marine digital media receiver offers 8 EQ Presets - Flat, Jazz, Pop, Classical, Rock, Techno, Vocal, and User. The User mode allows you to manually adjust the unit's Bass, Mid, and Treble. There is also an XBass (Bass Boost) feature that can be turned on or off.

LCD Screen: The Boss Marine gauge-style receiver features a front-panel LCD screen with bluish white illumination. The LCD screen indicates source input, AM/FM station number, and menu settings. This unit does not provide song/artist information.

Key Beep: The in-dash head unit provides an audible beep to confirm button operation. This function can be turned On or Off.

Marine Two-Way Speakers

Marine Dual Cone Speakers: The Boss MR6B speakers are designed and treated for use in the harsh marine environment. The marine dual cone speakers feature a cone woofer and cone tweeter. The speaker has a frequency response of 80Hz-20kHz and can handle up to 180-watts (max).

UV Resistant Basket & Grille: The integrated basket and grille are made of durable UV resistant plastic.

Mounting Dimensions:

  • Mounting Height: 0.875"
  • Mounting Depth: 2.25"
  • Cutout Diameter: 5.75"
  • Magnet Diameter: 3.695"
  • Frame/Grille Diameter: 7.5"
  • Number of Mounting Holes: 4 (spaced 4.75" apart)

Included Hardware: The speakers include stainless steel mounting screws and self-adhesive foam gaskets for a watertight fit.

Posi-Twist Connectors: The included Posi-Twist connectors replace old-fashioned wire nuts and crimp caps with stronger, more reliable connections. Just strip the stranded wires, insert them into the cap, and then hand tighten the two pieces together - the wire ends are locked between opposing cone shapes to create a dirt-, vibration-, and heat-proof housing. The connectors are also reusable.
