Switches playing sounds through my speakers??

[loudelectronics]

Anyone have a problem when they turn on switches and you get a humm through the speakers? If I turn on the bilge or blower I get a humm. When I use my taps I get a hum for up and down. Sometimes the taps will not go down until I turn off the boat and reset it.

Anyone have an idea?

Most likely a grounding issue.

Not sure where else to check. Looked at them all that I could find.

Did this just start recently or did this issue always exist? It is usually a grounding issue like zad0030 has stated.

I run 2 batteries that are isolated from each other. My stereo (amps,head unit,switch,ect)is on it's own dedicated bank, with everything else on the starting battery.

IMO....If you do it this way you should never get switch/accessory noise through your speakers.
