BOSS Audio Systems MGR450B Marine Gauge Receiver - Bluetooth, Digital Media MP3 Player, No CD Player, USB Port, AM/FM Radio, NOAA Weather Band Tuner, Weatherproof

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.

Works great lots a power feels solid nice face feels expensive really lol conects easy to my google phone radio eorks grest with cheap Canadiantire antenna i am going to bye another unit to replace the old one on are boat but round not square you will be happy with this unit .

Excellent. Well worth the money. Sound is clear, Bluetooth connection was instance.Highly recommend.

Beat quality sound

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!!!!
