Shark 100 Watt System by Cal from Beloit, WI written on May 16, 2011 I installed this system on a 2009 Kawasaki Nomad. I bought this particular system because of the price and the reviews. I'm not real handy when it comes to installing things, but I had very little problem with this system. I would estimate my total install time at about two hours - only because I had to remove the windshield and had a couple other hurdles to get over. I'm extremely pleased with the sound! It rivals systems costing a whole lot more. WOW!!
