I like the clean look of the stock head unit in my CL-S. However, I can't say the same thing about its sound quality. Many people in this forum have memtioned a "line driver" , but I have no clue what it is or what is it suppose to do. I already invested in aftermarket amp and speakers. Can someone recommend a good line driver??

Many thanks

 

I have heard good things about Audio Control, however I have never used their products myself.

It is called Overdrive...towards the bottom of the page.
