Operate car power amplifier with laptop charger?

I have a 320 watt car power amplifier and an old laptop charger with 19 volts and 3.42 A and I wanted to ask if it is possible to operate a car power amplifier with the laptop power pack?

The power of the charger is nowhere near enough! The laptop charger brings around 65W. The power amplifier laughs itself out loud… ☻☻☻

But would that break the power amplifier or would it work with 19 volts

But it does not provide any power or breaks the charger…
