    • Decent marine radio for the money
Style: MGR450B + 2 White Speakers
I am somewhat of an audio file in my home and car. So, I wasn't expecting much out of this product I didn't want to put a lot of money into the system. I was presently surprised. The sound quality is pretty good; descent amount of base and clarity isn't bad. Now I haven't had it on the water yet, I've only listened to it in my driveway, but I don't think my opinion will change. ... show more

    • Sounds great
Style: MGR450B + 2 White Speakers
Sounds great. I didnt need anything to blast across the lake from my boat, but just to listen as I fish. It installed easily and I just used the existing speakers. Now I have spares if needed. Bluetooth works great. I get a good signal out on the lake for a few local radio stations.

    • New sound system in trailer

We have a 3 year old 23ft. travel trailer,and I wasn't wild about the sound system that came with it. Replaced the outside speakers first, the factory installed speakers were tiny and needed to be cranked up more than the inside speakers. The BOSS speakers were much better, good for the price. Then decided to replace the radio. The Furion unit was a 4 inch cube so my choices were limited as there was not enough room to widen the opening and use a 2 DIN unit. Also, the Bluetooth would cut out if I moved my phone more than a couple feet from the trailer, and I knew it wasn't the phone. I first tried a Jensen radio which worked ok but not much power. I decided to go with this package and keep the Jensen as a spare. The speakers are almost a match to the outside ones, and installing the radio required adding small blocks for the lower corners. Added a short USB extension because I can't access the back of the unit when it is screwed into the cabinet. The inside speakers installed into the existing holes in the ceiling. The inside speakers are the "front" and the outside is the "rear." With the fader set even inside and out the volume is just about even. And the Bluetooth works great. Happy so far. ... show more

I was surprised how good this little system sounded AFTER I put the speakers in boxes. I bought Bbox Pro Audio Tuned 6.5" Speaker Enclosures from Amazon and they fit and sounded really good. Lots of bass and clear highs. I am not looking for a screaming loud system and these do get very loud. Not Sure how waterproof it is. It hasn't gotten wet yet. I did paint my speaker boxes white. They only come in Black ... show more
