hey there. Saw you at Berryessa before the 4th at the end of the day Saturday....we talked for a second about your motor & speeds when you were drying it off. Like that boat & welcome to the boards. As for your stereo question, shoot a call to the guys at Boatmaster's II in Dublin. If you don't know them, you'll want to get your servicing done there too. Anyhow, they likely know someone that does good work. Ask for Drew. (925) 828-5775
Good luck...jump on one of the Delta lunch runs next time around, they're a ton fo fun with kick-ass boats & good people.
