Last sunday I heard what sounded to be like a loud fuel pump whine over the engine. Turned out to be the speakers were inducting noise from the blower. When I flipped the swicth the noise went away. Any idea what would cause this, maybe a bad ground somewhere.

typically when you have feedback in a sepaker its due to a bad ground and or a speaker / coax cable running too close to a power wire...

Coax is typically shielded but if you run them on top of a power wire it doesnt matter. It will still whine...
