Factory audio details

I'm looking to approach audio upgrades from a different angle - does anyone know where I can find details on the factory amplifier specifications for the non-ml with nav? Better yet, has anyone used a multimeter at the speakers to measure the real output of the amp? I'm planning to replace one set at a time and will document my method...
Also, not sure if components changed - I'm in a 2009 is350
