Any SXS with a radio should install one of these. The one I order had the connectors already installed. It literally took me just a couple minutes to unplug the existing power and plug it right into this unit. It takes ALL of the whining out of the system, makes it crystal clear... IMO they should be installed with every system.
Fixed my problem. Worked great. You only need one though not one for the radio and intercom. The description is misleading. It has two power connections if you order it that way that delivers power to both the intercom and radio.
Works exactly as stated. Removed whine heard through the radio system.
