Style: MGR450B + 2 Black Speakers
Ordered this to put in my early 90’s Club Car DS. Sounds good and was easy to install. Seems to be well built and the instructions are easy to use. Bluetooth works flawlessly and displays song name on the screen.

    • Great unit one small issue.
Style: MGR450B + 2 Black Speakers
Just installed it yesterday. Easy follow instructions. Sound is way better then I had anticipated. For our fishing boat it is way more then we will ever need. Easy use and looks nice. We did have on issue with the order. The nuts for the screws were not the correct ones. The screws were to small for the nuts. This slowed down installation cause I had to find some to make it work. This was a surprise to me. The screw and nuts were pre packaged in thier own bags. This was a first for me ever that screws and nuts were not the right size.. Otherwise great unit. ... show more

These speakers are definitely load enough.. and the head unit was very simple to install. I don’t know anything about radios and even I was able to install in a hours time. Ran the wires And all.. for the price it’s well worth it.

It's compact enough to fit in tight places versatile full function did not need to install an amp was able to install in 20 minutes in a homemade project. Was blown away at how awesome it sounds. By the way this is the second one I made. My main reason was because of the built-in weather radio feature. We use it on our four-wheelers when we're out deep into the mountains when you can't tell when mother nature's going to come and sneek up on you. ... show more

    • Loud enough for Polaris Ranger at full speed and more!
Style: MGR450B + 2 Black Speakers
Review Image by Garrett Rezler Garrett Rezler
This was a DIY project for my sxs. This radio is sweet everything works as it should. The antenna works well in my area we will see when I go out in the trails. The speakers are super loud! They get very distorted at stupid high decibels but I don’t need it that loud. I turn this thing up to about 33 with Bluetooth and it is perfect even when you go 50 mph. This is exactly what I was looking for! To have good bass you will need a subwoofer which I didn’t install. ... show more
