Review: 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..
Review: 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.
