Heavy-first thanks so much for your reply and help.
I will make sure antenna is in , although did not remove it. I did clip off RCA jacks on one side of fast harness as they were not needed since I have none on radio and saw no need to run these. The other side by clip going into sub still has RCA wires.
Interesting you mention ground wire. I've been struggling with this. I wound up drilling a hole very close to where the sub mounting floor bracket is in the trunk through metal floor, sanding paint and screwing down eyelet into metal floor below carpet. Do you think I should redo or choose another place ?
Once again thanks for your valuable input.
