I have 2 12" Rockford p2s and a hifnotics amp. Recently while I'm driving they will turn off, the amp will stay on but the bass booster light will turn off, and the subs will turn off also. I'm not sure if this affects it or not, but my alternator squeaks and my headlights make a clicking sound and rapidly flicker but it's hard to notice, also once In a while one of my headlights or tail lights will randomly go out and then after I start the car up again they will come back on. Any helps great thanks!
