Good solution if you have the space to mount a second battery.

Would this work better:  A 2nd battery connected to the alternator
after the engine is running via a solenoid, with an APO3 between the
2nd battery and the radios?

The solenoid would have a delayed kick-in for the period when
starting the engine.  Have it kick in after stable charge voltage is
achieved.   Both batteries would get the full charge voltage that
way, no diode drop.
