As for the radio, the Metric Ton had an abortion of an old Pioneer in it when I bought it. Wind, bumps, or anything like that, and it would cut out, loose all the presets, and start back at 87.9. After about a week, I pulled the radio, and noticed that without the antenna in, it wouldn't work at all. Turns out, the only ground the radio was getting was through the antenna mast, which was caulked in. After running a separate ground to the radio case, I was good as new.
