Help 02 suburban reduce engine power when i jumped it in the morning.

I also got the code p1518. I tried to drive it but wouldnt go past 20 mph. So than i waited 2 hours jumped it again and sounds good as it should. What could cause this? Bad battery low voltage? I added a subwoofer to it 2 days ago and it ran fine for awhile could the amp be the cause thanks.
