28-30hz is as low as you should ever realistically need to tune for SQ (SQL) in an automobile playing music. Dont forget about transfer function guys, it already exagerrates sub 40hz material (in most situations).
You aren't gonna get 'sickening low end' or even very good low end with a 40hz tuning, I dont care what brand name is on the dust cap.
