I remeber reading about JBL doing signal processing in car with a product call magic 8 I think. Has any heard more of it. I believe it uses HK's logic 7.
It's called the MS-8 and JBL has delayed it's release twice. Last I heard it was supposed to be out about now. It won an innovations award at the '07 CES. It is an eight-channel unit and yes it uses logic7.
