For me it's because I want to turn the bass down, not up. Car booms quite well without boosting it more. I want to install the bass knob b.c
1. I'm using the stock head unit and it is very limited in eq control - cutting the bass cuts the bass everywhere including the front midbass
2. I have a toddler in the backseat quite often
3. I have a septuagenarian grandmother in the backseat sometimes

can you share a pic? Did you drill a hole and pull the knob through the bottom?
