I have a quick question concerning the Alpine 9886 headunit. I know it`s not the best to use dynamic bass features such as bass boost, but what about the bass feature that lets your widen your bass (Q0,Q1,Q2,Q3,Q4)? I notice the bass gets noticeably louder when I bring it up the scale towards Q4 but also less accurate, is toying with this feature when playing really loud bad for my woofer or am I good to go?

I wouldn't use it.
