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 cannot believe how good this cheap thing is. I put this in my parent boat and honestly, it sounds as good as the $800 radio I have in my boat. So happy with it. Holding up to the south Florida sun, pretty easy to use for my parents and again, it has power you wouldn't expect to get out of something this small with virtually no heat sink.

Easy to replace old unit with this one. Standard connect color codes used. Bluetooth connects easily and easy to navigate on screen menu. Powerful unit without need for external amp.

Installed on my boat no issues works well

Boss marine BT radio sound is ok. Sound quality is not at level of JBL gauge radios but it's much cheaper and after having 3 JBL radios (2 models) fail, I was motivated to try something new. This Boss radio diameter was way smaller & fit through my existing gauge radio hole. I made a circular adapter from a cup holder ss trim (with a flange to keep it centered). Seller was excellent, and the radio is good. Radio has an RCA pair for "front line out" and a "rear line out or sub-woofer". I have a sub-woofer and an amp (for which I wanted both RCA pairs for a front and rear lines out). My amp had an extra output line, so I used that for the sub-woofer, but I wished I had another sub-woofer RCA pair on the radio.

it works great now. when i first hooked it up i was getting no power so i called customer support and told them my problem. he said splice the red ground wire to the negative ground to the battery and it should work. i tried this and the power came on and it worked perfectly. he told me that they forget to mention this in the setup directions. i am very happy with the unit.

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.

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.AGAINWanted 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.

Works as described
