Stereo installation

[nipper]

I would like to install a marine am/fm/cd stereo in my 1991 V20 Cuddy over the winter. There has never been a stereo in the boat. I am curious as to where people think it would be best to install it. Would you install it "in-dash" style? Gimbal mount? Install it in the cuddy for protection from the elements?

Also, how about speakers? Where do y'all have your speakers installed? Your thoughts would be appreciated.
