  • Good radio for the price.
Style: MGR350B Receiver
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. ... show more

  • Very powerfull radio in a small footprint.
Style: MGR350B Receiver
Well I am not much of a reviewer but this time I wanted to write something about this radio. I got it very fast and since I couldn't install it immediately I decided I was going to test it at home with a speaker box I had and an external power supply. The speakers used in this test where 2 pioneer 6x9 4 way 350W speakers, and the power supply provides 13.8V at 22 amps (it doesn't draw that much current for sure). Well let me tell you that this little radio can move the speakers very well, and it is loud. I measured the sound pressure originated at 3ft with a white noise file and it measured 88db, if I put a sound track on the peak was at 90db at 3ft. Now for me that is more than enough power. Now the units gets hot in very little time when you push it near the max volume, and since the back is all sealed up, and the cover is plastic, I hope that overheating doesn't start to be a problem. Operation is very easy and BT pairing is as easy as it gets. I hope to install it on the boat soon enough and if it works as good as it did home I am sure that this is a winner. ... show more

  • Like the compact size of it.
Style: MGR350B Receiver
The media could not be loaded. Just wanted a simple radio for my fishing boat. Like the compact size of it. Did have to send original one back and get a replacement. I checked to see if it came on before ,installing, which it did. But after getting everything installed no sound. I did get the second one the next day and installed pretty easily since already had all the wires ran and speakers installed already. Connected the speakers and then to the battery. Turned on and Wal lah. Music. Works like I would expect it to. Hopefully lasts a while. ... show more

  • Very nice

Great upgrade to my old stock head unit that didn’t have Bluetooth. Fit in same hole in pontoon dash and hookup was easy. Sound is better than stock with same speakers

  • 2ND UPDATE- ALL AUDIO QUIT Update- It was a bad radio
Style: MGR350B Receiver
NEW UPDATE - GOT JUST ABOUT TWO WEEKS OF GOOD SOUND, WAS HAPPY WITH THE RADIO, UNTIL TODAY - PLAYING FINE , HAD SOME STATIC THEN RADIO QUIT ALL SOUND. STILL LIGHTS UP , SHOWS WHICH STATION, BUT NO SOUND AT ALL - TRIED BLUETOOTH SHOWS SONG PLAYING ON DISPLAY BUT NO SOUND AT ALSO. TRIED RESETTING ALL SETTING BUT NO SOUND OTHER THAN MINOR CRACKLE WHEN TURNED ON . SO NOW I HAVE A THREE INCH HOLE IN MY DASH, WITH A DEFECTIVE RADIO. AGAIN Wanted to post an update- ordered a replacement MGR350B and hooked it up to the same speakers but on "the bench " and the new radio plays GREAT. Can even you ent on the "Xbass" setting and it plays. So it turn out I got a bad radio, lesson learned to bench test before soldering and installing the right way and make sure it works. I have literally installed DOZENS of radios over the past 40+ years and have never had a problem. Now I get to do this the HARD way, either under the hood of a utv with wires cut to lenght or start completely over again and cut it all back out. This sucks, but at least I found the problem. But with a broken back and psoriatic arthritis this is really going to be painful to do under the hood. After spending all afternoon soldering and heat shrinking and making sure all connections are secure, I place it in the dash turn it on and it does play. Try to set the eq sound and any bass over 3 and half volume causes major sound distortion. Changed settings around and have found that this head unit just does not have enough output power to drive four speakers with any decent sound. Even disconnecting one pair or the other it does the same thing just with a little more volume than with four speakers connected. Any bass combined with any volume causes the sound to completely fail. I have the same speaker set up on my EZGO with a Sony head unit and it rocks no problem. The dash on Trail Wagon utv has no space to use a din radio so I had to go with a gauge style like this which fits and looks great but sounds terrible. Now after doing a professional soldered, double heat shrinked install ,all wrapped in taped secured so no branches can undo anything on a trail I'll have to go back in and cut it all back out under the dash and rewire for an amp under the dash. I had a good laugh turning on the XBass setting, this unit just said- no, with any volume over 10 it just cuts out. No power to drive speakers. At LOW volume this is a nice unit, you can get good sound. Going to put an amp in and see what happens, now that I have a three inch hole in the dash I kind of have to try to get the sound I want out of this unit. It does look good but it needs to sound good as well. I'll update after I get the amp in. Out of curiosity maybe Amazon and sent me a bad new speaker, I hooked them up on my EZGO with the Sony head unit and they played fine. I was really hoping this unit would work fine without an amp because I don't wanna add another device in the electrical system to add more draw. Maybe I got a bad radio? I see a bunch of the reviews bragging on how loud it is. ... show more

  • Excelente elección!
Style: MGR350B Receiver
Me encanta como se adaptó a mi scooter de gasolina. No tuve que añadir nada excepto los terminales para la cablería. No tuve que colocar una batería de mayor capacidad. Se adaptó a la cablería de fabrica. Suena muy alto sin necesidad de amplificador, emite un sonido de bajo potente y fiel.
