I was in the same boat as you last year (no pun intended

) - but didn't need speakers. Not sure if you're struggling with marine versus car but I went back and forth on this decision. I finally decided to buy a decent Panasonic car cd player (can't remember the model now) that can play mp3's (cd's). The car cd player actually sounds decent (with the original speakers which aren't anything to write home about) and if it does get wet or ruined, I didn't dump a whole lot of $$ into it.
I was a bit worried about marine versus car but there was already a cover for the entire player (it already had an older tape player). We like to play in the water but don't go crazy and get everything soaked. Will you have to install a new one or is this just a replacement?
Do you really need to use USB or SD? Would you consider using an MP3 player? How about an aux input in the faceplate? I would have done that, but last year there just weren't any out there in my price range. We could use our MP3 player ... maybe I do have one in the rear (can't remember). Just things to think about.... I'm a total geek so I love to look for this (and use) this type of stuff!
Other things to consider:
- Power rating (per whatever speakers you buy)
- Subwoofer outputs?
- Preamp outputs?
- Aux inputs (faceplate or rear)
While I was out there shopping (Best Buy), I saw many car cd players that used the SD and/or USB connections. If you look for marine, you'll pay 2-3x more for those features. Not sure what your budget is, but here's a cheaper one with USB support:
