I remember having a Sony head unit with BBE processing, a pair of Polk MM (mobile monitor) components in the front door, Rockford Fosgate components in the rear deck and 2 10" subs in a ported box run off a 5 channel amp mounted to the rear of the seat. I think I cried real man tears when they broke in and stole it (and to this day I bet I know who was behind it, but can't move on them)
