On my 1993 Suburban I have 6 speakers and when I installed a new Head Unit the center/rear door speakers would not work. I used Crutchfield for the my supplies so I called tech support.

Tech pulled up the wiring diagram and found the problem. 6 speaker units had the amp under the drivers seat. Their wiring info they supplied did not include this and it was a simple fix.

Talking to him what we determined was that the amp was only used on the 6 speaker system to power the middle/door speakers. I don't know that hold true for any other year but I suspect it does. In mine it is small black box and very obvious if you look under the seat.
