EL Ghia with Premium Sound issue.
After some help please.
Have a EL ghia and has the premium sound and had a JVC head unit installed and all the speakers work 100%.
I went to install facory headunit as the stacker in boot is more benificial to me and when I plugged it all in only the front speakers work.
There is a plug behind the dash that runs the rears but there is no where to plug it into.
The jvc head unit plugged into it with an adapter plug.
Any help at all to know how to I get the rear speakers running with the factory headunit??
Has the stacker din controller as well as the cassette headunit.
