Other Sp[eaker Concerns
Consider not cutting holes in the boat to install the speakers. If you ever experience a knockdown the speaker cones will not be able to hold back the flood of water. Also, should you ever want to sell the boat the potential buyer may not like the speaker holes. A small hole for speaker wires is much easier to fill in than speaker holes.Besides the autopilot, the speaker magnets can throw the compass at the helm off too. This depends on the size of the magnets, the quality of the compass, and the distance between the two.
