Amp Cause Battery Drain?

Had a neighbor who is a electrial tech diagnose my 98 mustang. I had the sit for a few days and battery would drain problem. We tested various issues and found the rear passenger side amp would draw power. My question is, is that something others have had issues with? I unplugged the amp and have had no issues, but want to see if that is something other people had issues with. I am wondering if anything else would be in that line I unplugged going back to the amp that could be the culprit instead of the amp.

Thanks for any insight.

Seems like it should be wired into a source that’s only active with the key on, no?

It's common for amps to wired to an "always on" source. There's a control wire between the head unit and the amp (normally blue) that allows the head unit to "turn on" the amps.

From the post on another forum, I feel the problem HAS to be in the amps. Otherwise it would affect BOTH amps.

Yes I posted in multiple forums due to not getting any feedback on other forums. I feel more confident now about the Amp being the issue.
