I have a single amp with one 8" sub in my silverado (I'm not that inclined with audio stuff, so I don't know how much power the amp has or anything). The amp was a hand-me-down from my brother, so it's been around quite a while (I would say 10+ years). About a week ago, I was on a 5-hour road trip, and all of the sudden my sub quit. I reached back and felt the amp, and it was pretty hot. I had driven that far in the past without issue though. Now, the sub doesn't come on at all. I checked all connections, and they are fine. Yesterday, I turned the stereo up really quickly, and it seemed to jump start it. The sub came on, but only for about 15 seconds. Does this sound like syptoms of an amp that has bit the dust? Any help is appreciated!
