    • Good for the price
Style: MGR350B + 2 Black Speakers
I ordered the smaller Boss unit with the included speakers. When they arrived, I hooked it up on the workbench to test the unit and the sound. With the speakers connected directly to the unit, it sounded ok. With the speakers hooked up to a small 2x20W kinter tripath amp, it sounds better. Speakers generally sound better when they're properly installed, but this unit is not going to blow your socks off. For listening to talk radio, the ball game, or quiet music while fishing or hanging out, it's just about perfect especially considering the price. If you want good sound and strong bass for partying, you'll need an amp and a subwoofer (there is a line out for both), and probably nicer speakers. The display is bright, and the controls are intuitive. One feature that is really nice is that the power button doubles as a mute/bluetooth pause. This is an excellent design, as I often find myself needing to mute music to hear someone talk, and holding a digital power down button or pressing pause on a phone is cumbersome. One reviewer noted that the bluetooth is easy to join, but I don't think you'd be able to hijack this from another boat due to the fact that Bluetooth is severely limited by distance. The unit does come with an antenna and a cover. I wish the cover allowed the connection of a tether. Time will tell how durable this is, but it seems well sealed and using dielectric grease on all connections is a given on boats. ... show more

    • Great head unit and speakers
Style: MGR350B + 2 Black Speakers
We installed this head unit and speakers in our 1987 Samurai. We removed the existing clock, trimmed out the dash hole a bit and pushed in the head unit. Couldn't use the backing plate because it is too tight with the air ducts under the dash. Had to trim out the old speaker holes a bit but not problem installing the new speakers. Sound quality is good for this unit and the size of the speakers. My only complaint are that it can be difficult to pair the BT for the first time and the volume on the unit has to be turned up to 25 or so to hear the sound loud enough while driving when using the BT, even when volume on phone is turn all the way up. ... show more

    • Great unit, but get an amplifier
Style: MGR350B + 2 Black Speakers
I am very happy with the quality of the audio system! I bought mine to install in my side by side so that I could have some music while I'm out plowing snow and it works great for that. The sound isn't super awesome, it's kind of "tinny" without much base, but part of that may be because I just have the speakers zip tied to the roll cage when really they should be mounted in a box. I intend to get some different speakers eventually. Also, I'm sure that an amplifier would help quite a bit. Overall, I'm happy with the quality of the unit and how quickly it connects to bluetooth. I would recommend you get an amp to go with it. ... show more

Review Image by Michael
There are a lot of mixed reviews of this stereo so i was a little nervous about purchasing it but it's gone well so far. I found it to be easy to install, just need a 3" hole saw for the head unit, a jig saw for the speakers and some electrical connectors. The sound is decent for an inexpensive stereo. Actually, I didn't expect it to sound as nice as it does. But I still ordered a pair of baffles just to make it a little better. Those will come in soon so will be interesting to see if there is much difference. I had no problem playing music from multiple sources. My favorite radio station comes in loud and clear. I've played music from my USB drive and the Bluetooth connection from my phone. All worked great. As far as longevity goes....time will tell. I'll post an update if things go south but no complaints right now. ... show more

    • Sounds Good
Style: MGR350B + 2 Black Speakers
I have only had this for a few weeks. I can't honestly say how it would withstand any rain, but I have washed my boat, and didn't spray the radio as it is not "Water Proof". I am pleased with the sound for the price. As for installation, wow, it took some contorting and a few words, but that's not the fault of the radio/speakers. It took around 6 hours or so to complete the entire install because I wasn't able to see up under the dash to install the bracket and nuts. I would recommend this product. For the price and sound, I don't see how you can go wrong. ... show more

    • Great value and awesome sound quality.
Style: MGR350B + 2 Black Speakers
I installed this system on a 2005 TXT golf cart. The head unit fit perfectly in one of the dash mounted cup holders. The speakers fit nicely into a set of dash mounted speaker forms that were also purchased from Amazon. Bluetooth connectivity was a breeze and the speakers sound awesome. Highly recommend this modern marine grade system. ... show more

Man these are a deal, so far they have worked flawlessly. They have been in the boat now for 4 months currently going through a winter. I live in Southeast Alaska so cold, wet, humid. On hot days there was condensation in the unit. My guess is that it’s moisture locked in from the factory when the unit was sealed hasn’t caused issues yet. My unit is in a covered cabin with an open back. The unit won’t be receiving direct rain but will be living in moisture. Will update review if something happens to them. The sound is awesome in our small cabin. I think the aluminum amplifies the sound. On step with a two-stroke you can for sure hear it in the cabin without it being cranked. ... show more
