Let's be honest, most head-units have controls to adjust the bass but having a small control located underneath and to the right of my steering wheel is a MAJOR convenience.

Their is no need to take your eyes off the road to QUICKLY and SAFELY adjust the bass. Not every song has the same lows and highs so it's really nice to be able to make adjustment easily. After all, if you have a really nice system and have spent hundreds if not thousands of dollars, this is a very small investment.

Highly recommended!
