Great speakers. I mounted them in my helm overhead to hear the tunes when running.
I am going to replace my other speakers this winter with larger fusion speakers. Had them on my last boat also and very pleased. Why change a good thing.

great sound, easy to install. I had to custom trim a cover, and could have done a better job. I contacted Fusion to see if I could buy a new cover and they sent me two at no charge!!

I would probably give a 5 rating but I really haven't used the system enough yet to give a truly positive 5 feedback, although if it continues to give me the satisfaction that I'm having I would come back and upgrade to a 5.
