Russound Audio Distribution, Static/Hiss/Noise (Boat)

Hello, i was hoping someone here could help me in diagnosing a Noise issue on this boat. They use Russound A-BK1 keypads to control the volume, and when turning up the volume there is a very loud Hissing noise. I found some high voltage wires running along with the speaker wires. Below is a picture of the main equipment location. I'm hoping that adding a couple ground loop isolators will fix this. What do you all think?

Hard to tell from the pics but do you have the power cables in the same tidy bundles as signal? that's a No No.

Never put signal lines parallel to power. Cross at right angles.

Separate bundles for Power, network, low voltage audio, high current speaker.

Ensure your grounds are all good and signal grounds are good. Connectors tight.

Sounds like you are getting induced RF noise.

Does the noise change when any motors are on? Go away when motors are off?

When on shore power or on inverter / battery? Or both.
