Third generation Bose systems were more like the Monsoon - an ordinary head unit with an external amp and different speakers. Fourth generation Bose (93-96) used special head units with low-level, high-impedance output that are not plug-and-play interchangeable. There are adapters that will allow replacement of the special bose HUs with a standard one.
