Some marine speakers include shielding so that they can be placed closer to
a compass (I am NOT suggesting right next to a compass). Unshielded speakers
are a frequent cause of "my autopilot doesn't work on some headings"
problem.

Are marine stereo speakers just high quality car speakers. As those
with rubber surrounds and plastic cones and dust caps. If not what
would be the differences. Thanks
