1. Car audio "stiffening" capacitors are designed with low leakage current in mind, usually based on carbon aerogel technology. They are not electrolytics.
2. You'll find that "big" amps that have huge capacitor banks implement some form of soft-start. Either timer-relay based switching-out of series resistor, or simply an NTC (negative temp coefficient) in-rush limiter for class-A amps, or tube rectifiers (the heating up of the filament provides the slow ramp-up) for tube amps.
