(you want to get this set up and figured out without introducing other variables from the head unit and such first) make sure teh polarity of the sub is wired correctly (pos/neg) try re-positioning the sub make sure none of the wiring for the amp is loose. (power, ground, remote, speakers) make sure the amp is grounded to bare, sanded metal. securely. |
