anyone know of a marine audio company that sells just a tweeter/crossover package, i need to replace/add some tweeters. would also prefer that there marine so they will standup to the salt water.

Lots of companies. Jl, Polk, Infinity, Pioneer, Jensen,

Ahh I just notice you only want the crossover and the tweeter? All of them will be a package with the mid, tweeter, and crossover.

Going to be hard just to get the tweeters and x/o's. You'll probably end up having to buy new speakers.

should actually be easy, any high end car audio shop should be abble tohook you up with the tweeters, the crossover is bsically just a capacitor, though you would be better with a good crossover unit if your running seperate amps.. the amps wil be happier being feed limited freqs, and they give you really good adjustment on the crossover points and slopes
