hey guys, im running 2 12 inch fusions with an audiopipe 1500.1 amp. Recently I've been having a problem where when i play a CD, and on certain songs that are loud and bassy the CD stops playing and my head unit switches back randomly to the radio. What could the issue be? I figured it was a poor ground and so today i regrounded it to a bolt that holds the seat to the frame, issue still persists. I plan on doing the Big 3 upgrade this upcoming week, but im not sure if that will be a fix for it.

Any suggestions?

Thanks!
