As you can see the MTX RZRSYSTEM3 stacks up favorably with the RF RZR-STAGE4 kit. Our head unit has more sources, a bigger screen, and displays album cover art when available. Our front speaker pods mount to your dashboard where they are aimed at your ears rather than in the foot well by your legs, allowing for better sound staging and more leg room. Each product in our kit is IP rated to ensure that no matter if you ride in the desert, through the mountains, or across the plains you can always take your music with you no matter what you might encounter. Additionally, if you plan on installing the system yourself, either MTX kit will save you time during installation as the speakers and enclosure are all pre-assembled and the subwoofer amplifier is integrated into the enclosure which means no second amplifier to install and you can start enjoying your system faster.
