I just finished wiring in a new head unit, amp and sub. My sub hits but when i play a song the sub fluctuates back and forth before the bass even kicks. When it does kick, its not a clean hit like im used to from fosgate, its super sloppy and fluctuates hard when the bass hits. I grounded both my amp and aux. battery and have good grounds. Not really sure what to check next. Any help?
