U0101 code due to amp draw?

Put a 1000w Rockford Fosgate amp in my 2014 equinox a few weeks ago and until now everything has worked fine. This morning after an hour drive with the radio cranked, I get back in the car and it won’t go in to gear. The check engine code is U0101. After a little googling it looks like it could be anything from a faulty ground wire to a bad alternator.

I pulled the fuse out of the amp and cruised back home without any issues. I put the fuse back in and so far it is working. I’m just wondering if my amp draw is too big for the alternator and I need to upgrade it to something bigger?
