## Description

BOSS Audio Systems MGR350B Marine Boat Stereo Gauge Receiver – Bluetooth Head Unit, No CD DVD Player, AM/FM Receiver, Weatherproof, USB, USB Charging

Review: Woke up my audio system - I got this for my Polaris RZR to run my system that includes four 6 1/2” and one 8” subwoofer along with 2 kicker amps, I replaced using the ride command (stock radio) and it woke up my audio system. The quality is good, brightness display screen. Easy to operate being that the buttons are a good size. Has features like builtin EQ, Bluetooth. It’s a good value for your money. I recommend this 10/10
Review: Good unit, why no power button? - Revised, the mute button is the power button - user error :-) - Unit was installed in a 2015 Can-Am Commander. I had to swap out the dash board, but that was easy. Slight modification to the hole in the dash that was done with a dremmel and sanding bit to just open the hole up a little. Worked great, fits snug and performs well. Sounds pretty good too, even with cheap marine speakers. I cannot see where you can turn the unit off, though. Weird that there isn't a power button. I guess you just mute it when you don't want to hear it. Wires are all clearly labeled so installation and wiring is straight forward. A lot of options on the unit. I added a usb and auxiliary input that I mounted in the glove box. Both just plug into the inputs on the back of the radio. Update - holding the mute button down turns the unit off. My fault. I've bumped up the rating to 5 because of my incompetence!

## Questions & Answers

**Q: What is the RMS rating per channel?**
A: Hello,
The MGR350B outputs a total of 30 Watts RMS per channel.
Thank you,
Boss Audio Support Team

**Q: I see it's a 3 year warranty on the stereo?? I got one almost a year ago and the screen blacked out after 6 mounts what and who do I get a hold of to**
A: You should check your order and either the seller or BOSS would be my guess.

**Q: How long are the USB and aux input cords?**
A: 12 inches

**Q: Why is the one without speakers more expensive? We have speakers.**
A: No idea.  I ordered the one with speakers (only a few dollars difference), but only used the head unit.  Saving the speakers in case things change later and I want to install them.

### ⭐⭐⭐⭐⭐ Good radio for the price.
*by S***A on November 23, 2024*

This is my second BOSS. The first one was still playing strong after 2 years of use and abuse in our boat. (We normally use every weekend 9 months out of the year. Got to love Florida. The old radio was still going strong until user error caused it to pop an internal amp or driver. (I was installing a new battery in a tight space and hooked the negative and positive backwards. (Yes there was some choice words said for not paying attention on my part.) The radio pushes the 2 6.5" speakers well. It does distort at full volume but for the money it does great. It's plenty loud at full throttle (still running a 2 stroke motor.) For out of the box easy install I would definitely recommend.
