Interesting timing. I have that exact same head unit. NO issues since I got the truck in January (PO installed Eonon)...then 3 weeks ago, NO audio. NONE. I had already picked up a JL MX280/4 to replace factory amp eventually because I heard that the factory DSP amp would be problematic, at best, but was definitely considered a weak point of the system. Anyways, my installer said that the factory amp was toast when tested last week for the swap. He bypassed the amp, installed the MX280 and I got my jams back right away. My guess is your amp went bad. Only $1300 to replace with OEM. Yeah right. Good luck.
