Ya, the way I ended up doing this was to wire the "new" head unit and
amp memory + and switched + wire to B+ This way, it's even more
incentive to finally install a battery cut out switch on the ground
side of each battery. Something I should've done a long time ago.

It's interesting, and ironic to me that the "memory" wire is a larger
gauge than the wire that would normally connect to the ignition
switch. Seems to me that the basic purpose of the latter smaller gauge
wire is to switch on the head unit/ The "memory" wire obviously
carries more current to the "guts" of the head unit. I'd always
assumed that wire only served to maintain user settings.
