If your Nakamichi is a "high power" unit (the 43w x 4 spec seems to indicate
so), then you cannot wire the (-) lead of the two speaker outputs together.
Those (-) leads are not ground.  Rather, they are the negative active outputs.
To adapt your Nakamichi to the input of the factory outboard amp you either
have to use the "line out" connections (if your Nakamichi is so equipped),
or use an aftermarket adapter.
