I installed a stereo/cd/sat.radio an amp and 4 speakers in my boat and I use it when haulin ass down the river{the motor is loud too so thats the reason for the amplifyer}, trolling fishin, cat fishing, stripper fishin off bottom, and pullin towables. I love having tunes on the water except when I'm largemouth fishin when a more stealthy approach seems to prevail.
