Tower Speaker In Boat Sound

Does anyone use their tower speakers to improve the interior sound? I like to be able to hear the music but I don't like to be run over by the volume or my wife and small son yelling its too loud.

I'm not so worried about the guy at the end of the rope and I personally like the exhaust note and sound of water. It seems that while underway speakers on the tower could be used to provide a more full interior sound without having it blasting.
