Thank you so much for this guide. Because I had only one terminal fail, I was able to do a different fix. I cut away the plastic covering of the bad terminal to expose the metal plate where the wire normally connected, drill a 1/16" hole through the plate, and solder a short length of wire to it. I soldered a male spade connector to the other end. Soldered on a female spade connector to the speaker wire. This worked well for me, although if any more connectors had gone bad I would have followed your excellent guide to replace the entire block of connectors. Again, thanks for posting such a thorough guide!
