Jay - Star has everything correct. Although the are intended to be marine tower specific speakers they are not going to be optimal for the rider. People on the sun deck or wakesurfing might find these speakers enough but it would be better to get into some "Pro Audio" for not a ton more. Price is not available on the JL pod yet and they do not have a release date as of this month.
I love the looks of the new JL grills they offer and the pod is built very well. All of the new Jl grills and speakers will be available by the end of April.
What part of Cal are you in? Give me a call and I can fill you in on what is working well on boats for us and answer as many questions as I can. I will be back in on Monday.
