I have a 2012 Sundance with the standard Genesis system,the sound quality is very tinny and very treble. We have tried everything asfar as adjustments in the system sound settings. My first thought was toreplace the speakers in the living area and maybe still need to update them.While looking at the wiring diagram I see there are provisions for Subwooferwiring. Can I add a Subwoofer and if so does it need to be powered or is thereenough power from the Genesis. I saw somewhere that Concertone had one thatcould be added. Would it be that simple?<o
