It may be a generational gap/music choice. I had a truck with a bigger sub 20 yrs ago that was more body shaking. This one doesn’t do that, but it greatly enhanced the sound for me. Sorry if I mischaracterized my experience.I also just finished the Fusion/Kicker combo. I'm curious to know what kind of settings or music you're playing to get that "thump in your chest". Mine sounds fine, but I'm definitely missing the thump. It sounds like a "good" factory stereo to me, that's about it. Thanks brother
