The wire that goes to the speaker has the (male plastic female pins). On the factory speaker is the (female plastic male pin) bracket that has terminals extended on each side, where the wires coming from the speaker are soldered onto. It looks like the bracket was fastened with a combination of glue and soldered square in the middle of the speaker.

I used a dremel to take off the metal overfill(just a tab) and the bracket came right off. I then used the dremel to remove all old solder so now im looking at a bracket that is close to new.

On the infiniti speaker, I see a plate with the same square that it lookls like it would fit. Should I just heat up the solder and then stick it on? Any suggestions would be appreciated.
