Hi there-

I have tried to connect the line that runs to the Nokia speaker of my
CK-1W handsfree unit to the input of my stereo amplifier, instead. (with
a speaker signal to line converter) But without success. The Nokia
speaker seems to be something other than a standard speaker; it seems
too heavy.  Does it have a small amp built in perhaps? Is there any way
of using something other than this Nokia speaker, I wonder?

Many thanks!
