My old head unit bit the dust. I tested all of my speakers (only front ones were factory stock) the old fashioned way: a D-cell and 9v battery. All gave contact static except for right front. I bought a set of Pioneer 4"x6" for the front, installed, and retested. Every speaker now works.
I bought the Alpine CDE-9870 head unit (my first Alpine) and a new wiring harness. I wired the harness and Alpine plug together (except for rear speaker plug, which is no longer in use). I plugged the Alpine in and it turns on. However, there is no sound from any of the speakers (except for small pop when turning the head unit on).
I tried the POWER IC setting (both on and off) with no help. I hooked my Bose into the external RCA connections. Both of those produce sound, but nothing to the car speakers.
I tested the speaker lines with my original speaker, with no results. I also tested with a flashlight bulb. Nothing works.
Bad head unit or bad wiring?
Thanks in advance,
Doc
