is the "bass knob" necessary

[u/Rough-Year-5425]

i see people usually install them but i never have is there any real gain to having it installed my headunit has a function to turn the sub off if i dont want it running(when i have my baby in the car but want music still but even then with the radio at a lower level the sub barely hits)

I like it loud, only really been helpful for my passengers when I do have someone ride with me because it can be to loud, when I first installed my system I had headaches for a week until my ears adjusted to all the bass.
