Not that dumb of a question, important though.
My Sister-in-law was over visiting my wife while I wasnt home, I come back and my wife says, "Kalee was using your boombox, but it didn't sound right, it was really quiet."
Thinking great, what happened, I start playing with it, checking everything out, plug in my ipod, sure thing really quiet on max volume. Unplug and look at he connections....
She plugged it into the line out! Somehow forced a signal backwards into the radio. I'm glad she didn't blow something. It was my M70...
