Question SPICE modelling for crossover design

I am using SPICE to try and get some baseline figures for a 3 way crossover I am working on. Does anyone know what the AC input on the simulation should be set to (ball park figures) for an amplifier output into the crossover?

Chris.

The standard value is 2,83 V rms, which translates to 1 W into 8 Ohm. Although the frequency response should not depend on the voltage, so any value will do up to the amplifier's maximum output.
