Tapped into the wrong audio junction point. Tapped into the correct point and was rewarded with audio. Good gain, but I have a buzzy, distorted 4 x 6 cone.
After prodding the voice coil by pushing on the center cap, I believe the coil is not blown or rubbing in the gap. Found that part of the cone is detached from the center cap.
After masking off the spider with a trimmed piece of paper (see photo) I applied glue (Titebond) to the torn area and applied light pressure to the speaker cap with a rolled up ball of paper towel and a piece of masking tape. I'll let it dry in place overnight.
Fingers crossed.
