Way better than expected!!
Easy install! Very please with the quality. I wanted something simple for my boat but decent sound. This system is way better than I expected. With only the 2 speakers this sounds way better than you’d think. I may add 2 more speakers just for kicks but this is enough for me..

On an 09' Rzr
Installed on a 2009 rzr. Easy to install and works flawlessly with my phone via bluetooth. I haven't checked to see how the USB works on it nor the radio as I don't have an antennae yet however it is hooked up to an amplifier with an 8" sub and two clarion speakers and it sounds amazing when riding with the loudness of my sxs. There's not much to say other than it's a very good option for probably a boat and certainly a sxs. While I had to modify (cut out a spot) and it's not flush but that's because the rzr is from 09 and wasn't built to have a stereo option. But it works great. I think it's an inexpensive option that will certainly perform to most people's standards provided they have decent speakers. It's loud, louder than most sound bars for 3x the cost.

works great
this receiver works great, it fit perfectly onto the existing round hole on my console where an old gauge used to sit.

Faceplate condensation repair DIY
So my radio fogged up after I turned it on and bench tested it for about an hour and a half. I was really disappointed. But being a professional mechanic I took the thing apart all the way down to the faceplate. It's only about 18 screws. Then I dried all the water and condensation, then I took my heat gun and got the whole faceplate and circuitry up to about 140 degrees. Then I closed it most of the way but put a straw for an air duster in there and purged out all the air and humidity. The air inside of an air duster is very dry. Combined with the heat I shouldn't have any more condensation. I closed it all back up and bench tested it for another four hours. No more condensation. Then because I'm going to use it on a jet ski I put extra E6000 sealant on the back where the wires come through. It's already sealed pretty well but a little extra never hurt nobody. The only complaint that I have is the factory should be doing this Purge. The other thing to note is this radio Maxed out at 170 degrees Fahrenheit. With no cooling fans and not much fins for cooling I don't know if the longevity on this radio is going to really last. But it held up to four hours of very loud play in my garage and didn't overheat or breakdown. So I'm installing it. I will update if it breaks down. If this hasn't been updated it still working well. Today's date is June 18 2020. As far as the sound it's pretty good once I put the speakers in the jetski. On the bench it doesn't have much base, but that's to be expected. Overall I think it's going to be plenty loud enough for my needs with the entry lamp and the sound quality is pretty reasonable. By the way it doesn't tell you that it comes with an antenna. And it also has 10 ft of speaker wires. Would have been nice to know that before buying that extra stuff. Oh yeah and it also has the hardware to mount the radio and the speakers. They're all Aluminum and Stainless Steel. It also has a gasket to go behind the radio and the speakers. Well I hope my review helps. If you found it helpful please click helpful so we can put it the top. Thanks

Woke up my audio system
I got this for my Polaris RZR to run my system that includes four 6 1/2” and one 8” subwoofer along with 2 kicker amps, I replaced using the ride command (stock radio) and it woke up my audio system. The quality is good, brightness display screen. Easy to operate being that the buttons are a good size. Has features like builtin EQ, Bluetooth. It’s a good value for your money. I recommend this 10/10

Awsome
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!!!!

after slightly shortening the U-mounting bracket to prevent interference with a dashboard cable harness the mechanical installation is quite simple and easy. However a bullet proof electrical installation is time consuming and complex if done properly, (common to all radios in this class) I used automotive type , (offroad vehicle!!!!) waterproof connectors for all wiring so dashboard can be removed, added master on off switch to prevent any battery drainage on my UTV and also installed a marine type high gain wip antenna with excellent results. The Radio is powerfull and delivers surprisingly good sound. The push buttons are somewhat small, forget operating radio when wearing gloves. I pipe my music in via my Samsung S7 or my I pad, works flawlessly. The little USB plug is a bonus. If you are in the market for a small 3" diameter radio give it a look, I like it and would buy again
