When I was dealing with boat wiring the stuff that seemed to work best is this: Boeshield T-9. It puts a pretty substanial film over the connection and penetrates very well. If the termination is completely exposed the silicone should work very well but if you need to make sure every little crevice is protected the Boeshield is good stuff. Click on the image of the big container to get a detailed sales pitch.
Go to Radio Shack and pick up some stuff called "Coax Seal". It is used to protect outdoor electrical connections and is a GREAT product. You can cut it, shape it and make a perfect seal. If and when you want to remove it, you can simply peel it back, do what needs to be done, and then re-apply it if needed. Any other approach stands to lessen the connection between the wire and jack and / or make a mess and / or give you problems should you have to remove the cable from the speaker at a later date.
GO BUY SOME OF THIS STUFF NOW!!! I'M NOT JOKING !!! : ) Sean
PS... This stuff works great for sealing / weatherproofing outdoor antenna connections, the point where your AC wiring connects to the ground rod ( once it is cleaned and re-connected), etc... Like i said, you can't beat it, it is EASY to remove and do maintenance on the treated connections AND you can even re-use it once done!!!
