Found source of a lot of noise on boat audio
Ive had this nagging noise over all my speakers whenever I installed a second battery with switch. Ive ready countless posts about ground, installing all at the same point, etc etc.
I thought Id share where I found the source of most if not all the noise hoping it might help others herding the same cats. The negative battery cable connecting the two batteries. Whenever I get any wire, even the ground for the head unit, I get a constant white noise. Ive since rerouted that cable along with the others since they dont play nice with each other.

I'm not sure I'm following. Which cables did you reroute to get rid of the noise? You still have the batteries connected together?

There is a single cable that connects one battery ground directly to the other battery ground (dual battery system). That cable is broadcasting a lot of noise.

I replaced all the cables with longer, heavier, versions so I could route that cable along the floor, away from any of the other wiring. I currently am having a ground issue with the Fusion head unit. Fusion customer service has been pretty good. Im only one year in to a three year warranty. The only way I can silence the noise from my head unit is to ground the outer ring of an RCA preout to the same ground as the amps. Something internal has failed and the head unit doesnt ground like it should.

I think you are focused too much on the ground circuit with a dual battery system.

Ground loop potentials can be very tricky. In CNC machines they cause all kinds of nightmares like false limit switch triggering.
