I bought my '89 32 foot Montego last summer and it had no functioning music. I'm focusing on the cockpit area right now and would like to put in a nice system with good speakers and some power. One of my decisions is about moving forward with a subwoofer (and the required amp). I would like good sound, great bass response, but am an old guy and don't really need a system that produces huge "thumping" and shattering volume. Most of my listening is at the dock (50' from the bar)and usually just cruise on the river. I have heard, however, that an amp and subwoofer will increase even that kind of listening. Any thoughts?
