Had a kenwood excelion x500-1 has been working good for years. Transfered over to this truck no issues for weeks. Today I had to pilot a wide load. I have power for the pilot sign, amp, and my vhf radio direct from top posts on battery. After a few blocks I could smell something burning was not a strong smell just faint. The raid on was turned down so I could use the vhf so I did not notice the sub quit working. When I got back I poked around to see what happened. No fuses blown for anything including the ones in the amp itself and the amp would power on but no output. See atached pic for inside amp. Plugged in my old mtx amp and drove to sterio shop where I purchased. They said it was the incoming power possibly a dead short or over powered. Tested all my connections and ohms on the sub and everything was good. Plugged in pilot sign and ran truck for 10 min or so testing and all was good. All wiring is brand new and if it shorted I should have burns elsewhere or blown fuse. Probably would have blown the fuse in the vhf for sure... so was it just luck the amp died or should I keep investigating?
