I am running 6 wetsound 650's and two jl audio 10 subs for my interior speakers. I need more highs especially when under way. I have been thinking abount adding some tweets probablt 2 pair. I have two channels on an alpine amp that are free. Here are my questions, What tweets do you like and do tweeters have to be marine. I like MB Quarts because they are so bright. The two in the front will get wet. With the two seperate free channels I should be able to set gains so they all blend. Any thoughts or ideas? Thanks gene
