Installed my FAE last week. It about three hours. This is the best bolt on I have done yet. It was easy to install with little frustration and zero regrettable moments. We surfed and wakeboarded this weekend and what a difference. We can hear the surfer and have conversation and the stereo does not need to be as loud. It did not effect my wake at all nor did I experience any power loss. My favorite part though is cruising at about 30 mph and listen to how quiet it is. All you hear is the wind and water. NICE!
