How many items are plugged into the back of a McIntosh stereo - is it three: antenna, amp cable, and normal Subaru connector?
Swapped in 3 different McIntosh stereos and none have any sound.
Swapped in another amp and rear speakers (I already know the fronts work).
I guess I need to test for power to the amp - It's supposed to get 12 volts I assume?
Can I test for an output signal from the headunit to the amp....what kind of voltages are those unamplified signals? Is there any access to the metal pins, those are some tiny round DIN connectors or whatever they're called, not sure I can get a multimeter pin on the pinouts?
Or any other way to test a McIntosh stereo besides plugging it into a car (which I'm not sure is properly functioning to begin with).
With a WRX 6 disc changer installed the front speakers work fine, just like any other Subaru, that's what I've been using for awhile.
