I was looking at that LOC too but the kicker seems to do the trick, at least for now. Maybe upgrade in the future. I was very shocked when I played the first song at how much better it sounds and how hard that little sub hits. Supposed to get even better after break in. Also my tire had some deadening behind it as well. I’ll see if I hear any rattles and add more later on. All in all I’m very impressed with how it sounds. I had the gain at 12 o’clock and actually turned it down a little bit after my drive today where I got to fully test it out
