Hey Gilly, thanks for the prompt reply. I have swapped all speakers at their locations (dash and rear deck) except the door subs, symptoms remain consistent. Have not tried plugging directly into the head unit, but my wiring continuity is fine, and have even changed out the fader pot. But I can do this, good idea. Antenna makes no sense either. This is driving me nuts. Time-wise, I'm nearing the time it took me to change out the motor and tranny. AAAAAAAAAARGH.......
