Mic PA app
 

Just thought I would mention the app I loaded on my iPhone regarding being able to talk to the rider like a PA system. I have a audio connection on my system in my boat but not a WS EQ with the mic. The free app Megaphone works good. Just plug iPhone head phone jack out into your system and be sure to have your volume not maxed out to eliminate the feed back and it works pretty cool to talk to the rider.
