I was adjusting my amp trying to get the setting tuned in a lil better when on one of my subs I heard a mild thump/pop on the lower notes. One sub made the noise each time and the other sub never did.. I backed the gain off a tad and it stopped.. Sub still sounds good and hits hard.. Never smelt anything or seen any smoke coming out the port.. Ideas? If it was clipping wouldn't both subs have done it?
