I think I want to replace the 6 Alpine STM-6666's (30 watt RMS / 100 watt max) in the cockpit of my boat with some Polks. What are the best Polks for the money? Sorry but search just hasn't worked properly since they re-did the servers (or whatever they did) a few months ago.
I think they fit in the same hole just have a bigger bolt pattern. If you are mounting directly to fiberglass I would double check, if mounting to a vinyl panel it should be easy. They fit in Chevy truck doors, in addition to lots of other vehicles (including european).
