Powered Subwoofer (JBL Venue Sub12) Makes Pop Static Noises When Loud

I have a JBL Venue Sub 12 powered subwoofer that I bought (knowing the amp had some issues). I just want to learn a little about troubleshooting a broken circuit and was wondering if anyone had any tips about what could be wrong with the amp. There is a video of the problem at https://youtu.be/yvfCJoarNj0 if you want to take a look!
