Im sorry i dont know which year the amp is to help you guys understand. The problem i am having is the amp will power on and when it does it gives a burp to my sub but it will not play any music untill its been on for about 10 minutes then it will play like nothing is wrong at the exact same volume as it would before the problem. What started this is when i went on a long road trip i kept the amp on the entire time. Ive taken a quick look on the inside and the board looks clean from the top. Ive also used an ipod directly to the the audio inputs with no help. Id appreciate it if someone could throw out some ideas of what it could be.
