I don't use CD's or MPS. If its not on the radio I don't listen to it. I mostly want it to listen to the ball games while fishing. Mostly for background noise and weather forecasts. Just don't ask me the score, or who's playing, I won't have a clue. I turn the stereo on in the garage while I work for the same reason. I couldn't tell you the last song played, who the teams are playing, score, inning, quarter, anything. The 5 seconds I do pay attention is lost to the minutes of concentration....
Actually I'm on-line at the moment to verify how to wire the radio up. Turns out its a '96 Clarion DRB4275 head unit with 30wX4. More than enough power for my needs.
