type 44 speaker impedance?

[cody at 5000tq.com]

The rear speaker amp is optional on t44's from and including '86.  
There were two radio options, a 4 speaker version and the 10 speaker  
(Bose?) version. If your car has speakers in the doors then it has (or  
at least had from the factory) the amp. From what I can tell with my  
ownership exeperiance (I think I'm up to having owned 10 '86-'87  
5000's, currently 3 including a Canadian model) the TQ's seem to all  
have the 10 speaker system and the non-turbo's tend to have the 4  
speaker system. With a 4 speaker system an aftermarker radio will work  
all of the speakers without issue. With the 10 speaker system the best  
way to get working rear speakers is to change them to aftermarket  
speakers and bypass the amp wiring.

All versions have the headphone adaptor on the rear deck which turns  
off the speakers and diverts the signal to the headphone jacks. The  
headphone switch is a very very very common failure point. The  
contacts get dirty and fail to pass the audio signal _anywhere_.
