Reviewed in the United States on February 24, 2024
I have went back and forth on which stereo to get for my side by side and i finally settled on this one. I read lots of reviews and have held back until i actually had time to use it to give honest review. Installation was very easy although one of the screws was missing to mount the tightening bracket on the back of the unit to hold it to the dash. Everything nicely labeled. I did not buy and amp as this has a small amp in it to power the speakers running to it. I ended up with 4 skar audio marine 6.5” speakers. WOW they sound fantastic without adding an external amp to them. This thing has some power on its own. Very easy to use and did i tell you its LOUD! I was just afraid it wouldnt be loud enough while riding the side by side but it exceeded what some of these other reviews said. The only con i currently have is that i also bought a boss audio aux/usb plug so i wouldnt have to use bluetooth and i could just plug my phone cord in and play music from my phone….. well it doesnt work or i just cant find the right setting but i go to usb mode and nothing plays and it doesnt charge my phone like it should. Everything is plugged in correctly. Anyway thats the only problem im having but this is a definate buy for a side by side!!!!

I got this for mine sxs And it's pretty amazing. It has way more power than I could have imagined and I don't even need to run an amp to my speakers which is mind-blowing to me. It has the fastest reconnecting Bluetooth I've ever seen. If you're connected to it and turn it off within one second of being turned on your phone's reconnected automatically. And the range of the Bluetooth is very impressive. It also has every hookup you could ever want coming out of the back. It has four channel speaker hookups it has auxiliary in it has low level RCA hookup and I don't think that's even all of them.

The media could not be loaded.
Pros:
Super easy install. More features than I need or will use. Easy to use. Pairs right up with the blue tooth. Sounds amazing with the Boss speakers.

Cons:
This may be user issues, but you need to turn the volume way up for the bluetooth setting. Don't forget to turn it down when you switch back to radio or the whole river will hear you.
Even thou it comes with a cover, the cover doesn't stay on when trailering the boat. I have had it fall off every time and have been very luck that the cover gets caught in the same place when doing mph down the highway. It would be better with a plastic snap type cover that has a positive grab when installed.

Solid unit for the money!!

Bought this to mount in an aftermarket fairing for my Harley Fatboy.
Works very nice. Sounds really good thru the Polk speakers I hooked them to.
Not sure how water proof it is yet, as I’ve not washed the bike since installing it or been in the rain since installation.
Time will tell, but for now, very happy with the radio !

Installed on my boat. I love that it has a rubber cover for the unit when not in use. My last one got wrecked from uv exposure.

I replaced a popular brand in a sound bar for my sxs. Although this unit needs a deeper area for installation it has performed great so far. Quality has been great and shipping was on time.
