Default 12V 100W power supply- 120mV p-p ripple

From the spec sheet: "120mV p-p ripple measured at full load by using a 12in. twisted pair terminated with a 10mfd capacitor and a 0.1mfd ceramic in parallel."

Is it too much for a car amplifier? Will it result in audible hum, or would it be dependent on the amps regulators?
I'm considering using a 4/3 channel car amp with a 100W switcher PS per side to power my active speakers. I'm doing the crossover in my PC.
