    2009 speedster 150 upgrade stereo

    I have a 09 150 speedster 255hp. I want to upgrade the stereo and have lots of questions. I am thinking of running a 5 channel amp from MTX to power 4 speakers and 1 10" sub. Also would like to put wakeboard tower speaker on. Questions: 1. Where can I mount the 10" sub and does it...
