    • On an 09' Rzr
Style: MGR450B Receiver
Review Image by 2171 Devil Dog 2171 Devil Dog
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. ... show more

    • Good buy
Style: MGR450B Receiver
Great head unit for a great price. I wanted a budget friendly head unit that still sounded good. Hooked this up to 4 6.5” speakers with no amp in my sxs and has plenty of power.

    • Awsome
Style: MGR450B Receiver
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!!!! ... show more

The media could not be loaded. Pros: Super easy install. More features than I need or will use. Easy to use. Pairs right up with the blue tooth. Sounds amazing with the Boss speakers. Cons: This may be user issues, but you need to turn the volume way up for the bluetooth setting. Don't forget to turn it down when you switch back to radio or the whole river will hear you. Even thou it comes with a cover, the cover doesn't stay on when trailering the boat. I have had it fall off every time and have been very luck that the cover gets caught in the same place when doing mph down the highway. It would be better with a plastic snap type cover that has a positive grab when installed. Solid unit for the money!! ... show more

    • Stop looking this is the one you want.
Style: MGR450B Receiver
I got this for mine sxs And it's pretty amazing. It has way more power than I could have imagined and I don't even need to run an amp to my speakers which is mind-blowing to me. It has the fastest reconnecting Bluetooth I've ever seen. If you're connected to it and turn it off within one second of being turned on your phone's reconnected automatically. And the range of the Bluetooth is very impressive. It also has every hookup you could ever want coming out of the back. It has four channel speaker hookups it has auxiliary in it has low level RCA hookup and I don't think that's even all of them. ... show more
