I went to the dealer and replaced the amp. It cost me $110 to diagnose it. Cost me $600 to get a new one installed and programmed. It fixed all my issues with static or no sound at all. However, the sound is still not as loud as I would like it. In addition it fixed my door chime issues...chimes not playing through the stereo but coming from the dash. As an FYI if you replace your amp, you better fix the water leak that causes the amp to short out. If you look just above the amp is a white nipple that helps hold the black plastic trim, outside the truck, in place. Really dumb design. Ford has literally violated the watertight integrity of the metal deck lid for the sake of some ugly black plastic. Anyway, that nipple fills with water and overflows and drips right on top of the amp and results in a short.
to fix the water leak, I used roofing tar around the nipple and sealed it off. So far, amp works great and no water leaks.
