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

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.

Excellent sound. Easy to install. Hi quality.

Installed easily and after one full season it’s still working well

sounds great

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.

Husband added to the boat and work very well. no static and picks up stations fine.

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!!!!

My boat came with a decent version of this but was a no name brand. This one provided a bit more output and clarity. I like the rca connections and the cover for it. The cover, like others have mentioned, will not stay on but it works while I have my boat parked.
