[about quick-disconnect for an auto radio?]

Most auto manufacturers wire power and speakers to a proprietary connector.
Different for Ford, Chrysler, etc... but auto sound shops can get a
harness for any make or model.

I'm burned out on harnessing: direct wire to batt n ground. the connectors are for removing the unit for parking in high crime areas eg trailheads, boat ramps, suburban Chicago, California, Oregon .....

That's why I suggested using the built-in harness and factory connector, for which mating
connectors are a standard item at auto-stereo-install outlets.
