Just get speakers with a poly (polypropylene) speaker cones and you'll be good to go. The non-desireable type of cone is made from paper which obviously doesn't do well when it gets wet. (and I am moving this to the audio forum)
Marine stuff is definitely the way to go with Wranglers. I have a Sony marine head unit with a Bazooka 200w 10" marine rated bass tube with remote level control. The standard size dash speakers (Kenwood plate style) work fine for me but I've installed bass blockers so they're only putting out high mids and highs. If you plan on asking them to produce any bass then you should upgrade them to the 5 1/4" drivers. The 5 1/4" soundbar speakers (also Kenwood full range) are setup to put out low mids and highs, the tube generates all of the bass I need and I don't have to worry about any of it getting damaged by water.
Where in Florida are you? I have a spare in the garage?
