BOSS Audio Systems MGR350B Marine Boat Stereo Gauge Receiver – Bluetooth Head Unit, No CD DVD Player, Built-in 4 Channel Amplifier, Weatherproof, USB, USB Charging

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

Installed on a 2009 rzr. Easy to install and works flawlessly with my phone via bluetooth. I haven't checked to see how the USB works on it nor the radio as I don't have an antennae yet however it is hooked up to an amplifier with an 8" sub and two clarion speakers and it sounds amazing when riding with the loudness of my sxs. There's not much to say other than it's a very good option for probably a boat and certainly a sxs. While I had to modify (cut out a spot) and it's not flush but that's because the rzr is from 09 and wasn't built to have a stereo option. But it works great. I think it's an inexpensive option that will certainly perform to most people's standards provided they have decent speakers. It's loud, louder than most sound bars for 3x the cost.

Installed this radio and speakers into my boat in less than 1 hour. Awesome product with awesome results. It came with easy to follow directions the quality to really good. Bluetooth function works perfect, speakers have great sound quality, and offers a solid fit into my center console.

Things to know that are confusing about the product description, reviews, and QA on this page: 1 - The round one does not come with an antenna. An antenna is not mentioned anywhere on the box or in the manual. I do not know why there are so many QA questions stating that it DOES come with an antenna. 2 - The switched-power-on wiring is pointless; the unit has non-volatile memory, so it doesn't lose clock, bluetooth or radio settings when completely disconnected from power. I'd suggest you wire both power leads together. This is really important if you use a battery switch or breaker panel to disconnect everything when you are away from the boat. Other than these things that I wish I could have confirmed before I bought it: It's fine. It sounds okay, the interface and menus are okay, the installation instructions are okay. It feels pretty cheap in operation, but it does function. I installed it immediately and it has had a week of being in very, very hot and humid conditions inside my boat and there have been no issues. When it dies, I would be 50/50 on replacing it with the same model or spending more for a different design. Power draw seems very low in operation.

I have went back and forth on which stereo to get for my side by side and i finally settled on this one. I read lots of reviews and have held back until i actually had time to use it to give honest review. Installation was very easy although one of the screws was missing to mount the tightening bracket on the back of the unit to hold it to the dash. Everything nicely labeled. I did not buy and amp as this has a small amp in it to power the speakers running to it. I ended up with 4 skar audio marine 6.5” speakers. WOW they sound fantastic without adding an external amp to them. This thing has some power on its own. Very easy to use and did i tell you its LOUD! I was just afraid it wouldnt be loud enough while riding the side by side but it exceeded what some of these other reviews said. The only con i currently have is that i also bought a boss audio aux/usb plug so i wouldnt have to use bluetooth and i could just plug my phone cord in and play music from my phone….. well it doesnt work or i just cant find the right setting but i go to usb mode and nothing plays and it doesnt charge my phone like it should. Everything is plugged in correctly. Anyway thats the only problem im having but this is a definate buy for a side by side!!!!

Fits 3 inch hole. Blue tooth, USB connection. Weather. Fm radio. Works great. Easy to install. I used only two speakers but 4 is better.

We have a 3 year old 23ft. travel trailer,and I wasn't wild about the sound system that came with it. Replaced the outside speakers first, the factory installed speakers were tiny and needed to be cranked up more than the inside speakers. The BOSS speakers were much better, good for the price. Then decided to replace the radio. The Furion unit was a 4 inch cube so my choices were limited as there was not enough room to widen the opening and use a 2 DIN unit. Also, the Bluetooth would cut out if I moved my phone more than a couple feet from the trailer, and I knew it wasn't the phone. I first tried a Jensen radio which worked ok but not much power. I decided to go with this package and keep the Jensen as a spare. The speakers are almost a match to the outside ones, and installing the radio required adding small blocks for the lower corners. Added a short USB extension because I can't access the back of the unit when it is screwed into the cabinet. The inside speakers installed into the existing holes in the ceiling. The inside speakers are the "front" and the outside is the "rear." With the fader set even inside and out the volume is just about even. And the Bluetooth works great. Happy so far.

Easy to install and works well. You may need some splitters if you have a 4 channel amp.

after slightly shortening the U-mounting bracket to prevent interference with a dashboard cable harness the mechanical installation is quite simple and easy. However a bullet proof electrical installation is time consuming and complex if done properly, (common to all radios in this class) I used automotive type , (offroad vehicle!!!!) waterproof connectors for all wiring so dashboard can be removed, added master on off switch to prevent any battery drainage on my UTV and also installed a marine type high gain wip antenna with excellent results. The Radio is powerfull and delivers surprisingly good sound. The push buttons are somewhat small, forget operating radio when wearing gloves. I pipe my music in via my Samsung S7 or my I pad, works flawlessly. The little USB plug is a bonus. If you are in the market for a small 3" diameter radio give it a look, I like it and would buy again

Cansado de que los convertidores de Bluetooth para autos no servían al 100% este estéreo lo puedes esconder en cualquier parte de tu automóvil y vuelves a tu auto viejo a uno del siglo XXI súper equipo
