Phil,
I retraced all of the wiring and everything looks good. It still make the noise, only when the engine is running or when I first turn the key on. Any other suggestions?
Thanks,

I had the same problem with my supra. Ran the power and ground from the head unit to the battery and problem solved. I heard the hiss when my ballast pumps were on.
I had a similar problem on my Supra. My problem was due to the video cable that was running from head unit to VISION system. As soon as I unplugged this (had no intentions of playing videos on the screen) the issue was resolved. Not sure if you have the same issue but thought I would mention it.
Rather than retracing the wiring to the head unit did you re-wire the head unit?
You need to move the head unit power wire from the helm power wiring as I shared in my previous post. The power and ground wireat the helm are dirty and full of noise and almost always at a different voltage potential than the amplifiers... If your head unit is still connected to the helm power wiring instead of being moved to the big amp or the distribution block, you will have noise.
What you hear when you first turn the key on is likely noise from the computer(s) and the fuel pump, indicating you have a ground-plane issue.

Mike,
I have been in contact with Bell Marine about your boat. I have given them a few items to check. Let me know if there is anything I can help with.

Phil,
Thank you very much! I ran a direct power and ground to the head unit per your last post and it solved all of the noise issues!
