The speaker has a magnet in in it. Is there as standard as to how close it can be installed to the compass or autopilot. Appreciate any info I can get.
Thanks

Minimum 3'. Check the effect by turning the speaker on and off and observing any change in the compass/flux gate.

I was involved in some experiments about 10 years ago where we showed that passing an offshore oil platform or large ship within 50' caused large deviations in flux gate compasses and could cause unintended course changes while on autopilot.
I have done it many dozens of times and nary a degree change...all kinds of bridges.
Wonder why bridges do it to some pilots and not others.

I couldn't see installing a speaker anywhere near my helm.
how are you going to hear the engine. If someone wants to listen to music on my boat they have to go out on deck.
I know every rattle whistle,clatter, clunk or tink my boat makes, but I'm a single engine and where I boat there's nobody to tow me home. If the compass or auto pilot are in use that means the boats running.
no time for tunes I'm running my boat.
I found out the hard way that you don't pass underneath a large bridge while on autopilot. Very sudden course change.
